[SOLVED] Re: [YBA] libroffice Hebrew input stopped working
Dear ILUG colleagues,
The issue that I reported on this list regarding broken Hebrew input using
Debian Wheezy LibreOffice with the Hebrew keyboard layout from the
Keyboard Layouts plugin is resolved by installing LibreOffice from Wheezy
backports as follows:
Add
deb http://ftp.debian.org/debian/ wheezy-backports main
to /etc/apt/sources.list.
Do
apt-get update
apt-get -t wheezy-backports install libreoffice
Thanks to Lior Kaplan for suggesting this solution.

an update about this issue - I installed the libreoffice packages from
libreoffice.org and the /opt/libreoffice/... writer can handle Hebrew input
fine in my Debian VM. Furthermore,
briefly after starting it /usr/bin/libreoffice was able to handle Hebrew
keyboard input as well, but it permanently reverted to its previous, erroneous,
behaviour after moving away
~/.config/libreoffice (And the libreoffice under /opt - the one from
libreoffice.org is still fine).

Jonathan,
1. Have you updated the libreoffice packages recently? Which
version of the packages you have ?
LibreOffice 3.5.4.2
Build ID: 350m1(Build:2)
I have made no changes recently other than to use the Update Manager on
a regular basis. I suspect that some update caused this problem.
As there 3 updates to the package since release of wheezy, please use dpkg -l
libreoffice for the package version... You've given the software version.

I was able to reproduce this offending behaviour on an up-to-date VirtualBox VM
running Debian Wheezy x86-64 with a mostly new UNIX user account. I used the
Debian system's libreoffice packages. I did notice I was able to type Hebrew
inside a terminal and inside Iceweasel/Firefox. Enabling Complex Text Layout
(CTL) in LibreOffice did not help. Finally I should note that the
system's LibreOffice is working fine in this respect, on my Mageia Linux x86-64
host.
I have yet to try the LibreOffice packages from
https://www.libreoffice.org/download/libreoffice-fresh/?version=4.4lang=en-US#change
on the Debian Host (but I will).
So it seems like a bug in the recent Debian Wheezy and I suggest you report it
to the Debian bug tracker.

Subject: Question about how to make a living from open source
Hi All,I am in need of assistance.
I am currently working as a freelancer coding stuff in a company.
However, although I am making good living, this does not scale much (and
promotion is out of the question :) ).
Anyway, I am looking for ways to scale.
Be ready to drink a lot of coffee, and say goodby to your significant
others (family).
One of the ideas that were given to me is to compile couchbase or postgres and
distribute the binaries with a support license. Find 4-5 customers which pay
big bucks
and make a living. Though, not much scale there either, unless i start taking
employees...
Customers that pay big bucks work with suppliers who have big bucks.
That's not you, so forget it. That is, large customers work with large
suppliers. For example, you you have a quality solution, but a larger
supplier has only a partial, poor quality solution, then the company with
big bucks will buy from the larger supplier with the poor quality, partial
solution and not you. That's how the business world works. Big business
works with big business, small business works with small business. The
size equation trumps quality and availability.
Another idea is taking employees but people in the business are telling me i am
better off staying a freelancer than taking employees. Not sure what is true
here.
When you take employees you need to have enough money to pay them for at
least two-months ahead. You will need to incorporate, and hire an office
manager/secretary. Your employees get paid first. If there is any money
left afterwards then you might get paid. Is this what you want to do?
That's how you want to risk your savings? Having employees is like having
children. You have to guide them, instruct them, motivate them and wipe
their noses. Are you built for that?
One other idea I had is hosting complex solutions for sites. Like postgresql
couchbase etc... which is difficult for the average joe and making it scale
like heroku
etc...
Can someone give me a clue?
Yes. Reverse the process. Instead of wanting to scale and then looking
for an idea, work on the idea first. If you have a great idea for a new
technology or service then look for partners. And if you don't have a
really great idea, forget about trying to scale.
That's not my 2 cents speaking. That's my NIS 600K debt speaking.
- yba
Thanks!
Tzahi Fadida.

Subject: How to sort a file by pure ASCII order?
I encountered a counterintuitive behavior of 'sort' in modern Linux
releases.
I checked the sorting behavior of sort, as installed in Debian Jessie
and Ubuntu 14.04 LTS.
Turns out that the default behavior of sort (with locale=en_US.UTF-8) is
not to sort by ASCII order, but as if letters and digits are more
important to sort order than punctuation marks.
Attached please find a sort-test.txt file and the output of
sort sort-test.txt (as the file actual.txt).
To show how would the output look like using pure ASCII sort, I sorted
sort-test.txt using python-sort.py (attached).
and got the result reproduced in correct.txt (attached).
The problem is then what options would get GNU sort to sort like
python-sort.py?
Can anyone shed a light on the matter?

[YBA] new package for simple HTTP file upload
Dear colleagues,
I have posted a new package for simple parsing of multipart/form-data file
uploads with no dependencies on third-party code at
http://tkos.co.il/downloads/misc/libmpfd-1.0.0.tar.xz
The package is derived from code by Grigory Dmitrievich Gorelov posted at
http://grigory.info/MPFDParser.About.html
Sourse code is C++.
The libmpfd-1.0.0.tar.xz adds autoconf capability and a Mongoose example
and some refactoring of the code. Does not handle filenames with spaces or
Hebrew, yet...

Re: [JOB] freelancer for long-term
Hi vordoo,
The projects range in time from one or two days per week for a year,
to 12 hours a day for two months.
The work is
* doing a board bring-up for a bleeding edge Broadcom board
* porting a Windows command and control application to Linux
* porting a video application from an old ARM SoC to a newer one with a newer
kernel
* write a gtk+2 desktop on LXDE
* write a PCIe host-to-host bridge driver for a PLX chip
* writing a high-level packet handling library for DPDK for DPI applications
and similar.
The rationale is that we have more projects than we can currently do, the
expertise we need is in different areas, and the time frame is limited, so
it makes sense to develop a pool of freelancers who can meet specific
needs rather than to try to find a single salaried employee who would try
to do everything. We would like to have the best of both worlds, meaning
that we would like to develop a stable pool of consultants for the
long-term.

If the reboot occurs as a result of a hardware fault, you might never see

Re: partly OT: notification of url when connecting to open wifi
Hi Erez,
For each AP you need to maintain a table of client connections that are
accepted, meaning that the client has presented some type of credential
or payment or whatever.
Packets from clients that are not accepted are routed to some
authentication or payment gateway, with possible port translation.
The accepted client table does not have to be on the AP itself. It is
usually held in a RADIUS server upstream. The authentication gateway also
does not need to be on the AP itself. It can be upstream and does not have
to be the same as the RADIUS server. You can also have more than one
payment gateway but use the same RADIUS server.
That, in a nutshell is how it is done. There's a lot of netfilter/iptables
smoke an mirrors going on on the AP.

Re: partly OT: notification of url when connecting to open wifi
Hi Erez,
In the implementation that I worked on, we used iptables to route
unauthenticated HTTP to a proxy (Hughes libHTTPd) on the AP which then
presented the client with a page from some upstream payment gateway. Once
the client was authenticated, we changed the iptables rules to allow
direct routing of all packets. I am not so proud of this design. It was
a hack that we slapped together quickly. You might
be better served by looking at http://www.chillispot.org/.

Jonathan, if we are talking about walled garden/captive portal
implementation under linux, i'll take the opportunity to ask something
related.
how does the AP redirect every web access to the login page (for non
accepted clients)
i guess using a transparent proxy with a redirection page, am i correct ?
if i am correct, i would like to know:
1. does the AP allow real DNS access, or does it return the IP of the
AP for every dns query. (and if so what about DNS cache ?)
2. what webserver/proxy is used to return the same redirect answer
to every requested url

Re: when linux was linux
Hi Erez,
The problem is the desktop concept - a bunch of applications that
work very hard try to guess what you will do next and tell you what you
want.
If you just run X with a window manager then you wont have this problem.
But before you blame the distros, think about how we got here. We wanted
Linux to be an alternative to MS Windows, so we made it (at least in the
major distro manifestations) more like MS Windows, and this has been
relatively successful. The downside is that it really is more like MS
Windows.

Bingo.
This happened to us in Talpiot. Bezeq upgraded the lines without telling
us that the old D-Link wouldn't work so well. I replaced it with an Edimax
DSL/Wifi router and that solved the problem instantly.
Of course, everyone denied the story, the ISP (BBL) and Bezeq.

I use Bezeq for my infrastructure and Bezeq Beinleumi for my ISP.
Every hour or two my internet connection is disconnected. It will

the modem is a D-Link DIR-320 router, which connects my Ubuntu machine
via cable and various other devices (laptop, Nook, Android phone) via
wireless.
If your infrastructure was upgraded from an aDSL-2 to vDSL/aDSL-2 combination
units, you need to upgrade your modem. You can tell, by the maximum speed
BEZEQ can offer you. If it is 15m or less it is aDSL-2, if it is more, than
the hardware was upgraded.
The problem is the upgraded hardware does not do aDSL-2 very well, and you
should upgrade to vDSL.
BEZEQ does not tell people this when they make the upgrade.
While you are at it, you should upgrade your router. It's going to have all
sorts of problems running out of space for routing tables, and very likely
does not reset NAT tables when the line drops.
I have had really good results with a D-Link 6740vn router from BEZQ which
has an integrated vDSL modem.
It's nice because you can log into the router and check the speed and quality
of the DSL connection. You can even run BERT (bit error rate) tests on the
fly.
Note that almost no one in Israel had an aDSL connection to their central
office. BEZEQ quietly replaced every line they could, and are still working
on the rest with fiber optic connections. Each connection is 100mBit and gets
split at the corner to DSL lines.
So your actual DSL connection is a most a few hundred meters, and often a lot
less.
Geoff.

[YBA] Linux on Intel R1000GZ
Hi Linux-IL colleagues,
Last night I installed CentOS 6.3 on an Intel R1000GZ server.
My intent at first was to install Debian Wheezy, but I was unable to find
information on drivers for Debian that support either the RSTe or ESRT2
(LSI) configuration of the RAID card.
So after giving up on Wheezy I tried to install Ubuntu 12.04 desktop. This
distribution detected the RAID in RSTe configuration, but apparently not
correctly since at the end of the installation it was unable to install
grub anywhere.
It seems that Intel only supports RHEL and Oracle Linux on the R1000GZ
servers, so my third option, which succeeded, was to install CentOS 6.3
with the BIOS RAID in RSTe configuration.
The reasoning behind not trying harder to find a solution for Wheezy
is that by using a base OS that supports the board OOTB I will have a
better chance of getting automated notification of updates for the RSTe
drivers and any other proprietary drivers without manual searching. In any
event, I only intend to use the CentOS as a host OS for other mostly
Debian-based OS's. Is this reasoning sound, or am I a wimp for giving up
on Wheezy? In general, would installing the base OS that best fits the
board regardless of other (mostly ideological) considerations be the best
advice to customers, considering the support implications? (I am assuming
that selecting the board for the OS is not, in general, an option.)
Purim Sameah,

[YBA] diff'ing kernel source trees
Hi Linux-IL colleagues,
To diff two kernel trees based on the same version from the mainline, one
of which might have been built, I assume that doing make clean in the
tree that was built and then recursively diff'ing each
.c
.h
.S
.sh
.pl
*defconfig
Makefile
Kconfig
is sufficient. Are there other files I should diff? Is there a list
or regex in any of the FAQ's that has this specification?
I tried the recommended diff -Naur -X ./Documentation/dontdiff
but it still diff'ed a lot of binaries.

Re: [YBA] diff'ing kernel source trees
Hi Elazar,
Good idea.
Unfortunately neither tree has .git. One tree is from TI dvsdk402_psp and
the other tree is from a vendor who made many additions and changes to
the TI dvsdk402_psp kernel. The dvsdk402_psp kernel is based on 2.6.32.17.
Thanks,

Can't you copy one tree into the other and then use git diff? (Assuming at
least one of them
has a git repo it came from).

Re: [YBA] diff'ing kernel source trees
Hi Muli,
Thanks, I did not know about the mrproper target.
The problem was that the previous owner of these trees left a lot of
uImage_copy, old_uImage.sammy, and dozens of .swp and .swo files in
the trees along with board-dm365-evm.c, board-dm365-evm.c.bak,
board-dm365-evm.c.dave, etc. No target however smart can hope to find all
of these files.

My recommendation: cp -al the dirty tree into a new copy (or cp both

the copy using dontdiff as above. There should not be any binaries in
the resulting diff.

[OT somewhat] DDOS attacks, where to report?
Dear Linux-IL colleagues,
An associate of mine who runs a hosting service has been the victim of
persistent DDOS attack, apparently from botnets that are mainly located
on other countries.
His Israeli service providers have responded to these attacks by cutting
off his service.
Is there someone in ISOC-IL or the police who will take a complaint
seriously? I suggested that he file a complaint with the police, then with
the copy of the complaint in-hand ask his attorney to call the service
providers to demand restoration of service.
Any ideas?

Re: [OT somewhat] DDOS attacks, where to report?
Hi Shimi,
You are suggesting that there is no recourse to DDOS attacks, that
Israelis are fair game for foreign attacks and it is no one's business
except for the victim.
The ISP does need to suffer in this case, in that the ISP has allowed an
act of war to be committed through his service. I see little difference
between this and the cab drivers who transport illegal workers from the
Palestinian territories to jobs in Israel. We require the drivers to take
some responsibility for whom they transport.
I am suggesting that ISP's be charged with some level responsibility for
investigating and reporting these attacks. That's in the national
interest. I suspect that in the cases of large institutions, even
non-governmental institutions such as banks, that there is in fact some
national response, but that this protection is not currently extended to
smaller players. If a rocket hit's your home you get some protection at
the national level. If a DDOS attack from a hostile government attacks
your business, it's not in the national interest to provide
some level of protection?

Does his ISP need to suffer because of his business? Bandwidth cost their

The customer/the ISP can purchase specialized firewalls to defend against
DOS/DDOS attacks.
Hi Eliyahu,
Which Israeli ISP's offer such services? Do any of them?
The subject of the attack can try to approach the local police and in some
cases they will work on taking down the botnet, see for instance Dutch police,
FBI and other European forces spending time on these cases.
Do the Israeli police actually investigate DDOS incidents originating in
foreign countries?
But unless your friend shows that he is taking serious steps to prevent this
type of thing in the future no ISP has to allow him onto their network, there
are ISPs that specialize in hosting sites that are prone to being attacked but
the price is
obviously accordingly.
For example?

requirement for individuals or ISP's to report such crimes as there is
with other crimes? Does the government view the liability for damages
resulting from such attacks as a private responsibility like burglary or
fire insurance even when the attack is committed by an enemy of the state?
Is this written anywhere and is there any applicable case law? How big
or persistent does a cyber attack have to be for it to be considered a
public issue? Or has no one in government ever considered the question?

Subject: Re: [OT somewhat] DDOS attacks, where to report?
Why should the ISP have that responsibility?
They are as far as most of us are concerned not even supposed to do DPI (deep
packet inspection) and without DPI they have almost no way of telling the
difference between a site that is under attack and a site that just posted
something that is so
popular that everyone is going there also effectively DDOS'ing...
Once the user reports the crime to the ISP, does the ISP then have any
responsibility to report the crime, like other crimes?
The responsibility to go to the authorities lies squarly with the victim,
elthough you might expect some good citizenship from the ISP if they signal
illegal activities they still have a very hard time telling the legit from the
illegitimate
traffic.
This is not true in general under Israeli law, as I have found out myself
from unfortunate personal experience. See
http://he.wikipedia.org/wiki/%D7%90%D7%99_%D7%9E%D7%A0%D7%99%D7%A2%D7%AA_%D7%A4%D7%A9%D7%A2
Also ISPs in Israel don't even bother to put virus affected customers in
quarantine where they are blocked from accessing the internet until they clean
their computer(s), something which is fairly easy for them to implement and
very much in the
ISPs interest so why would they do more complicated things like dissecting
attacks?
Not necessarily analyzing attacks, just reporting them.
(I know some of the better ISPs outside of Israel do this)
As far as an example of equipment goes, tweakers.net did a review on an anti
DDOS firewall appliance in 2010:
http://tweakers.net/reviews/1648/riorey-rx1810-how-to-put-a-firewall-through-hell.html
Such an appliance would iirc not be usefull at the ISP level since it utilizes
traffic patterns

This law is about telling the authorities about a CRIME THAT IS GOING TO
HAPPEN, that you know about, so that the authorities can stop the criminal
PRIOR to the act of crime.
Unless you claim the ISP KNOWS that a DDoS will happen (in the future) to the
customer (they can't possibly know. like I've already said - chances of
catching the source behind a DDoS are almost nil) - I personally find it
difficult to understand
why you think this law is relevant on our case...
Hi Shimi,
This law is in fact applied to ongoing crime as well as futire crime. It's
not enough that you know someone has been trafficking Ukrainain girls for
two years already to exempt you from reporting it if you find out about
it.
Also, not even sure that this is called a crime that happens within the borders
of Israel. After all, the attacker, and his 'associate' computers, are all (for
the lack of better knowledge) outside the borders of Israel when this happens.
Again,
the Israeli police (or Government) has no jurisdiction over the whole
Internet...
It's is enough for the victim to be affected in Israel for it to be a
crime in Israel.
I think it is time for me to quote from the Serenity Prayer:
God, grant me the serenity to accept the things I cannot change, The courage to
change the things I can, And wisdom to know the difference.
Of course, I wish your friend luck if he opts to pursue this anyways, with the
hope for: a) any sort of success, and b) that he won't waste so much time/money
on his attempts...
I'm wondering if there isn't a public policy initiative that we should be
pushing, perhaps through ISOC-IL. I mean, I'm all for prayer, that's
necessary, but sometimes concrete action is required. The problem here is
that some small players are getting soaked disproportionately for the
county's wars.

Re: [OT somewhat] DDOS attacks, where to report?
Hi Shimi, The policy that I would expect is: 1. Possibly requiring licensed ISP's to offer extended anti-cyber-attack protection, for an extra price. 2. Requiring licensed ISP's to provide a specific basic level of cyber security as part of every offering. 3. Requiring reporting of cyber attacks that pass some level of damage or persistence or that can be identified as originating with a particular organization to a national information center. 4. Requiring on-line financial services and other specified services to implement specific security policies. It's clear that the country is under concerted attack.

Unless you claim the ISP KNOWS that a DDoS will happen (in the future) to the customer (they can't possibly know. like I've already said - chances of catching the source behind a DDoS are almost nil) - I personally find it difficult to understand why you think this law is relevant on our case... Hi Shimi, This law is in fact applied to ongoing crime as well as futire crime. It's not enough that you know someone has been trafficking Ukrainain girls for two years already to exempt you from reporting it if you find out about it. This is not an ongoing crime. Your friend server is offline, the attacker noticed and stopped bombarding. ISP is happy. That's the reason they disconnected your friend at the first place - they knew their infrastructure will no longer be attacked when they do. This is the reason why people DDoS in the first place! Because it works... Also, not even sure that this is called a crime that happens within the borders of Israel. After all, the attacker, and his 'associate' computers, are all (for the lack of better knowledge) outside the borders of Israel when this happens. Again, the Israeli police (or Government) has no jurisdiction over the whole Internet... It's is enough for the victim to be affected in Israel for it to be a crime in Israel. This may be true (I don't know our law. it was more of a quandary). Still, jurisdiction over the entire Internet, not located in Israel? That's not simple! I think it is time for me to quote from the Serenity Prayer: God, grant me the serenity to accept the things I cannot change, The courage to change the things I can, And wisdom to know the difference. Of course, I wish your friend luck if he opts to pursue this anyways, with the hope for: a) any sort of success, and b) that he won't waste so much time/money on his attempts... I'm wondering if there isn't a public policy initiative that we should be pushing, perhaps through ISOC-IL. I mean, I'm all for prayer, that's necessary, but sometimes concrete action is required. The problem here is that some small players are getting soaked disproportionately for the county's wars. I already asked and couldn't see your answer, so I will ask again: What actions do you want your government to do against the computers in China, North Korea, or Arab countries? Please elaborate. Don't just say that 'someone needs to do something' - tell us what can they do that they don't, that would help in situations like this... also tell us what should they do after they somehow made 20,000 computers clean, just to realize that in a keystroke, the attacker infected 20,000 other computers, and all what they, basically had no influence whatsoever. b.t.w. why are you so sure that those are country's wars ? Running an innocent IRC server is very likely to get you DDoS'd too. A decade ago, DALnet, the biggest IRC network users-wise (AFAIK), had been on netsplit more time than not, because someone DDoS'd them. For months. The network lost servers

Subject: Announcement : http://vim.begin-site.org/ - The Vim Beginners' Site
Hi all,
I would like to announce that today I started working on
http://vim.begin-site.org/ - the Vim Beginners’ Site, which is a static site
generated by the Jekyll offline CMS (which I learned today, after finding a
post of someone who converted his site from XML+XSLT to it, as I considered
using XSLT first). Currently many links are broken and the content is
incomplete, but:
1. The site's source code is open-source / open-content (MIT/X11 | CC-by ).
2. One can easily contribute to it:
* http://vim.begin-site.org/contribute/
* http://vim.begin-site.org/source/ - points to the BitBucket repo.
3. I'm noting ideas for resources here:
*
https://bitbucket.org/shlomif/vim-begin/src/131c08549754e47c0ccf3cbdf202e6b6c0300172/vim-begin/jekyll-prototype/TODO.txt?at=default
(short URL - http://is.gd/WtjpJE ).
4. I'm planning to continue working on it myself.
---
The inspiration for the site is http://perl-begin.org/ , which I also created
and still maintain. I registered the begin-site.org and begin-site.com domains
to serve as placeholders for more sites like that, and will be happy to refer
their sub-domains to similar sites (e.g: c.begin-site.org , cpp.begin-site.org ,
clojure.begin-site.org , python.begin-site.org , emacs.begin-site.org ,
cooking.begin-site.org , etc.).
Some people on IRC told me there was a genuine need for a site like that about
Vim, and since I like Vim so much I decided to go for it.
Enjoy, and I hope to see you contributing.
Regards,
Shlomi Fish
P.S: while they are still not there, I am planning on putting some 100%
non-intrusive non-animated images
http://en.wikipedia.org/wiki/Project_Wonderful ads on the site, similar to
what I have on http://www.shlomifish.org/ . I hope you will not be too offended
by them, but you can use an ad blocker, or alternatively set up a mirror of the
site under a different domain, without the ads. So I think it is fair, given
that I pay for the domain and the hosting.

Hi,
I have an idea which involves going somewhat deep into the bowls of the Java
Jar class loader when using the official Oracle JDK 6 (and soon 7).
To verify this I started looking at the JDK source code but it's not small and
I'd like to try to trace through it while it executes Java programs.
Does anyone here have experience in doing something like this and can give me
some useful pointers on how to do this?
I'd like to be able to do gdb java -jar HelloWorld.jar and single-step

Thanks to both of you.
To give more details of what I'm after - I want to know whether the class
bytecode address points into the mmap(2)'ed jar file or into malloc(3)'ed
memory. I think I
found part of the code path inside the jdk source which does this and now I'm
trying to determine what are the situations in which each option is taken.
Can JMX do that? The code I'm looking at is written in pure C.

[YBA] new kernel ramoops feature anyone?
Dear colleagues,
I am working on a patch that adds a new feature to the ramoops kernel
feature.
The patch is an extension of the current ramoops facility, see
http://lwn.net/Articles/377890/.
The patch adds a platform-specific reservation of ramoops memory in early
boot, so that the ramoops area can be:
a) at a constant physical RAM address
b) guaranteed never to be overwritten by the kernel or userspace (other
than by the ramoops driver that is)
These two features mean that even for volatile RAM, as long as:
a) power is maintained
b) the bootloader does not clear the RAM
c) subsequent reboots use kernels that have the new feature and define the
ramoops area at the same RAM address
then the contents of the ramoops memory is preserved through reboot and
you can recover the contents of an oops or panic dump that happened before
the reboot. In fact, you can even log arbitrary data in RAM accross
reboots.
Why do you need this great feature so badly?
You need this feature to help you debug or to monitor various drivers and
kernel features that oops or panic while in interrupt context or on boards
where there is no other candidate memory mapped device to write to, (i.e.
no available NVRAM, no FLASH or no free FLASH) and there is no way to
write to a device that might be protected by a lock or a mutex, such as a
write to an EEPROM from interrupt context.
From your experience, does this feature have a chance of being accepted
into the mainline kernel if implemented for ARM and PPC?
TIA and hag sameach,

advised to get an Alzheimer's test, or just flagellated by Russel King. If
only the latter, then I will make the effort to do the work in the format

Re: [YBA] Lenovo z580 BIOS setup horror story
Hi Sara, With the new BIOS, was finally able to get Wheezy installed on the Lenovo Z580 using the B2 netinst CD and non-free firmware rtl_nic/rtl8105e-1.fw, brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw. Now the problem is that when I install guest OS's such as Ubuntu 10.04, the machine freezes at some point during software update downloads or just waiting long enough and the CPU fan goes into full speed.

Re: [YBA] Lenovo z580 BIOS setup horror story
Hi ILUG colleagues, Three weeks after sending my new Lenovo Z580 to CPM I received it back, in good working order. They replaced the motherboard and the hard disk and that solved the BIOS problem. I'm not really sure what problem that wouldn't solve, or why it wouldn't be cheaper for Lenovo to just sell these laptops without disks and motherboards in the first place if they are going to have to replace them in any event. I was not able to get any version of Debian to install on this laptop, so I ended up installing Mint, using a 240GB SSD instead of the original HD. It boots in less than ten seconds. So after two-and-a-half months I finally have a working Core i7 laptop. I hope that this is the end of the story.

I have a 2 TB disk with ext3, and I don't have anything close to the 1 hour
boots you report (even one minute looks excessive).
Both ext3 and ext4 are journalling filesystems, meaning that after power
failures, only a relatively small journal of the last modifications
needs to be replayed, rather than going through the entire disk.
Is it possible your filesystem for some reason has journalling disabled,
or improperly configured? Try tune2fs -l on your filesystem and look
for suspicious parameters. Look at Filesystem features and verify
there is has_journal. See that it doesn't force a full fsck every time
(Maximum mount count can very well be -1 and check interval 0).
Might also be the disk going bad - perhaps check with the S.M.A.R.T. utility
smartmontools
There are a lot of failure modalities that SMART can't see. Maybe just try
copying the disk to a new disk and comparing the behavior.

Re: [YBA] kernel compile errors with GCC = 4.6
Hi Nadav,
Your point is well taken.
-Werror has been in GCC for a long time (4.2.2 at least).
I don't know how long it has been a default flag in the kernel, but I
understand why it is. You really do want the compilation to stop and
to take a look at what is going on.
For other projects I think that the Makefile or build system that is
distributed with the project should only use -Werror after checking that
the GCC version is the same as the version used by the developers for the
release.

Dear linux-il colleagues,
GCC 4.6 introduced many new warnings that cause -Werror to stop the
compilation for some platforms, such as powerpc, in various files.
Oh, I didn't even know they finally introduced -Werror... Good.
Why is this good?
In the (very) old days, there was a clear separation: The compiler
gave you *errors*, and a separate program, call lint,
(http://en.wikipedia.org/wiki/Lint_%28software%29) was used to find
various risky code, possible bugs, unused variables, and so on, and
warn on them.
I *don't* like the fact that modern compilers decide to complain on
issues of questionable style, such having a variable which is never
used, using = (deliberately, not ==) in an if's expression, and so
on. I like even less the trend to use something like -Werror to *abort*,
not just warn, on these cases.
After our last Hspell release, I started receiving complaints from
various people who used slightly different compilers than I did, so got
different *warnings* that I didn't get. This was very annoying, because
although I could (and did) fix those warnings, most of them did not have
any merit, and the only reason why I made many of these changes was to
appease the compilers. In one example, the compiler wrongly deduced that a
variable could be used before being set, which was false (I can explain why,
but the details aren't important here). In another example, a header file
defined a few static arrays, and not all of them were needed in each
including file - and the compiler complained about the defined-but-not-used
static arrays.
I think all of this is bad. I agree that it's useful to have a tool
(lint, gcc -Wall, or whatever), for the *developer* to find possible
problems. But the developer shouldn't *have* to change the code to
appease this tool, if he doesn't want to. The compiler that a *user*
of this code uses should definitely not attempt to look for such
possible problems, and most definitely should not abort the
compilation if it finds some. The contract between the programmer and
the user is that the programmer writes the code as carefully as he can -
and the user tries the best he can to compile it, NOT find reasons for
the compilation to fail. See also http://en.wikipedia.org/wiki/Postel%27s_law
If -Werror is used in a big-enough project, there is a very high
probability that compilation will always fail when a new version of the
compiler is first tried. I fail to see why this is a good thing.

Re: [YBA] kernel compile errors with GCC = 4.6
-Wall and -Werror are fine when the build system uses them WRT the GCC
versions under which they have been tested.
The flags serve a useful purpose if the developer has been polite enough
to specify the GCC version under which he released, and if there is some
easy way to build without the flags.
I agree that not all software should have to compile without warnings.
However, there is a deeply held superstition among managers (and some
coders) that no warnings should be allowed in a released product. This
reminds me of a 8200 commander who once publicly chastized an officer (Dr.
Gabi Leshem) for having a ברירת מחדל in his code. The commander stated
that he would not tolerate any מחדלים in his unit.

Recent kernel versions surely have all these warnings fixed. The kernel in

Unless a new compiler or optimizer suddenly became smarter and
recognized some new possible mistakes that the previous one didn't.
Or, in the case of this bug (see the link that someone gave earlier in
this thread), that the warning only happens in some rare combination of
#ifdefs, where, for example, some variable is defined but never used.
Since the goal of the user is to *use* the program (not debug it), and
since issues like unused-but-set variables certainly don't prevent
the program from being used, I think it's stupid for the user's
compilation to abort when the compiler discovers such issues
Down with -Wall -Werror!

Re: [YBA] kernel compile errors with GCC = 4.6
Hi Nadav,
From a technical viewpoint of view, forward compatibility is not feasible
in software. 3.4 might compile fine now under GCC 3.2, but it is likely to
break in some future version of GCC that, for example, warns on goto, or
more realistically, warns on the string - that might be a dash, hyphen,
or minus depending on the interpretation of your editor.
I think that it would be best if kernels were released with the list of
compiler types and versions under which they were tested before release.
It is not useful to pretend that there is no necessary connection between
particular GCC versions and particular kernel versions. The compiler is in
fact a part of the running kernel.

According to the Linux README, Linux depends on gcc, at least version
3.2. It doesn't say you must use some specific version - which means
that Linux's make *should* finish without aborting on any newer
version - including versions which added new warning messages. If it
doesn't, it's a bug.
I'd hate for Linux to declare that it only works with a specific version
of the compiler. I routinely compile the latest kernel with a 3 year old
compiler (gcc 4.4), and don't have any problems. Other people may be
compiling a 3 year old kernel with the latest snapshot of gcc, and they
shouldn't have problems either.

[YBA] kernel compile errors with GCC = 4.6
Dear linux-il colleagues,
GCC 4.6 introduced many new warnings that cause -Werror to stop the
compilation for some platforms, such as powerpc, in various files.
My question is in general, is there somewhere where the relationship
between kernel version and gcc version (or other compiler version) is made
explicit?
Is there a discussion of this issue somewhere? Is anyone interested in
receiving patches to fix errors and warnings flagged by newer compilers in
recent kernel versions that were released with previous versions of GCC?

Re: Announce: Hspell 1.2
Hi Orna, Nadav, Google wont stay with any outdated version and Nadav wont succeed in suing Google for anything. AGPL is an own-goal in the truest sense. Google will simply reverse engineer Nadav's code in a clean room envrionment, if they think that they need it. And if they don't, as you hint, we all lose. The result of using the AGPL will simply be to limit the adoption of the code by smaller players, for which everyone stands to lose. At best, they will modify the code for their needs and let the download button provide the original, unmodifed code, which is Ok if they are not distributing code only a web service. It would have been better for humanity and possibly for Nadav's pocket to have released under dual license, proprietary and a less restrictive Open Source license. It's not too late, please reconsider. Consider the small number of improvements, if any, that have been contributed to Hspell over the years by anyone other that Nadav and Dan under the GPL license. If the licence had been at least LGPL the code would have found its way into OpenOffice, which would have given OpenOffice an advantage in the Hebrew market and might have resulted in more user-contributed code. - yba On Sat, 3 Mar 2012, Orna Agmon Ben-Yehuda wrote: Date: Sat, 3 Mar 2012 06:56:39 +0200 From: Orna Agmon Ben-Yehuda ladyp...@gmail.com To: Nadav Har'El n...@math.technion.ac.il Cc: linux-il@cs.huji.ac.il Subject: Re: Announce: Hspell 1.2 Nadav, Dan, First - thank you!

You can find the new release in the project's homepage: http://hspell.ivrix.org.il/ Over two years have passed since our previous release. In that time, we continued to improve Hspell's accuracy and further enlarged its vocabulary, reaching over 24,000 base words. We continued to document Hspell's spelling standard, which strictly follows the decisions of the Academy of the Hebrew Language; The document, http://hspell.ivrix.org.il/niqqudless.pdf, now spans over 80 pages. We also fixed a number of bugs.

Until now, Hspell was licensed under the terms of the GNU GPL version 2. From now on, it is licensed under the GNU AGPL version 3.

But nevertheless we consider this an important change, so I'd like to further explain its rationale. The GPL was designed to promote free software, and protect its ecology. The GPL allows users to freely share and improve the software, while ensuring that the improved versions remain free forever, for all of society's benefit. Nobody is allowed to market their improved version as a proprietary, closed-source, product. However, in recent years the proprietary software industry started undergoing a transformation: Whereas most software used to be distributed as a product, software is now often distributed as a service. Users do not install the software on their machine, but rather use it through the service provider's Web site. Such service providers discovered that they were exempt from the GPL's terms: As they were not distributing binaries of the software, they also did not have to distribute source code. Nowadays users frequently find themselves using software through a Web site which is based on free software - but the user cannot install this software on a different server, or modify it. Very often, the user cannot even know which free software is providing the service he or she is using. We've unfortunately seen this happening with Hspell too.

It's a question of how you look at the world - the way it should be or the

Hi,
I'm curious why you think the end-result (and I'm not talking about the
situation seven years ago) isn't better than we could have had with an LGPL
Hspell.
If Hspell were LGPL, it would have been tightly integrated inside OpenOffice,
and commercial products from IBM, Sun and perhaps others that build on it
would have had Hebrew spell-checking out of the box. But its users might not
know where this Hebrew spell-checking came from, what its spelling standard
is. And they would likely get old versions of the spell-checker.
Instead, what is happening now, is that Hebrew spell-checking is a
plug-in (or in Linux, a separate package, e.g., hunspell-he in Fedora).
Any user can get it, easily and freely, and while doing this he or she will
always have the latest version, and be aware of exactly which spell-checker
they are using, its spelling standard, and who to complain to in case of
problems.
Frankly, I never understood why OpenOffice not just GPL. Why the
insistance to allow Sun and IBM to create proprietary versions of it?
Nadav.

Re: Legal actions against Ministry of Education, anyone?
Hi Boaz,
The Israel Ministry of Education doesn't have any schools.
The schools are owned by what the Ministry calls the baalut, usually
a city or local council or Ottoman Society (amutah), or private company.
The ministry sets policy in general and provides money to pay some of the
salaries, but is ambivalent about what software any particular school uses
(except for the fact that the Ministry might offer free licenses for some
commonly used software).
So your legal action should be directed against the baalut, probably
your own local council or municipality.

Hi,
First, just to give a quick update on the thread I initiated here lately (titled
Preparing to convince to shift to non-propriety documents formats) and that
still
lives on. Below the bullet list update is the actual content for this message:
* Basically, my meeting with the school principal was more of an acquaintance
meeting then anything else. The new school site that replaced its
(terrible) predecessor works much better on my Chrome/Linux system. The
site even have an internal online Word editor so I can view the weekly schedule
with all
the nice images within with little problem. Obviously, not all is so
bright - read on... .
* Just now, when I looked at that site trying to open the weekly schedule, it
downloads it to me instead of showing online with the wonderful online Word
tool so
I'm back at square one in that sense. Obviously, until a
more thorough solution will be implemented we'll always chase our own tail
fighting silly usage and
other problems (probably the teacher should have uploaded the document
differently or use a Word version compatible with the online Word engine. You're
imagination is always limited in comparison to what reality will bring
about...).
In the mentioned thread some of you mentioned Ofek system and guess what - we
were referred to it recently. Only for enriching purposes etc so no immediate
fire to
distinguish luckily. I've checked that site. They have an official
requirements document that mentions the dependency on Windows and IE
(BTW both are needed.
Chrome/Windows will not be good they say. Classic isn't it?). The document
dates back to May 2011 and they say there that they work to make the site
compatible with
other browsers (they don't mention compatibility with other OS).
I'm sick of that.
I wanted to know if anyone have ever attempted some legal actions against
specific school or some other higher level entity against this discriminating
situation
that is clearly not going to change soon without decisive action.
IANAL, but it looks like a rather sure bet to win such a case isn't it? After all, its
the compulsory and free education laws context that we operate under and
under such laws the official policy cannot force you to spend hundreds of NIS
(at minimum) to be able to do educational activity that's supposed to be free.
Further
more, IMHO the official policy cannot even recommend spending those NIS as
its clear discrimination (its not mere few NIS, its hundreds of them, at least).
I wanted to learn if such attempts have been made in the past or if anyone has made some
work in that direction (and can share his/her interim findings).
Thanks for the feedback,
Boaz.

Subject: Re: Preparing to convince to shift to non-propriety documents formats
What are the school's arguments for not accepting a PDF? The unsurmountable
difficulty of installing acroread on the
teachers' computers? Or is acroread so hopelessly behind the times that it does
not allow marking and annotating? If the
latter, then OOO...
It is not reasonable to ask everyone to install Acroread, or anything else
that is not available by default when you buy a computer from Office
Depot. You would have to send out an instruction sheet and call a parents
meeting to explain why this is necessary. You think that they will do this
just for you?
I think the principal should agree that requiring the parents to buy a computer
with Office just for homework is quite
unreasonable. I'd try thos argument before anything else, and maybe instead of
everything else.
No. The principal correctly assumes that most parents have a computer with
MS Office. This is a reasonable assumption. There is absolutely no
requirement to buy something that everyone already has, because you
already have it anyway an no one buys it so it doesn't cost anything in
any event.

I am not sure about the time not being ripe.
In the last year, I installed for two non-technical family members a
copy of OpenOffice (one a full fledged Linux, but the other a compromise
Windows+OpenOffice).
They both faced a few hardships when people sent them Microsoft Office
documents and they didn't look exactly as expected, but I was able to
convince them that it was in fact the other person who is behind the
times ;-) And the documents *were* readable, even if didn't look
perfect.
And for users, this is a saving of 500 shekels (last time I checked).
I don't see how this fact can be ignored in Israel after the summer's
protests. This is actually the reason why I installed OpenOffice in
these two cases - it's hard to justify adding 500 shekels to the price
of a computer which cost around 1000 shekels (plus a few hundred more
for the legal Microsoft Windows).
A slightly more productive line might be to claim that you are no
longer using desktop computers - only mobile devices, and for these
you need either PDF or Google docs.
I believe my Android can read Microsoft Office documents out of the
box :( But it's true, with all these non-Microsoft devices around,
Microsoft's stranglehold on the word processor document seems to be
coming to an end.

I found that this approach, mobile devices, works. For example, at the
American School in Even Yehuda it helped convince teachers to accept and
give assignments in PDF or via Google docs. The techers made this head
switch about three years ago when the younger students who were
the early technology adopters demanded it. It didn't come from the

Hi all,
I'm about to meet my daughter's school principal on the subject of the formats
of documents the school spreads around
routinely, like the weekly schedule. In short - they are using .DOC MS Word
format and I don't like it as I cannot
cleanly open those documents on my computer (which runs Ubuntu).
Although I'm quite old in the Linux world and probably heard over the years
most of them - still I prefer having a
refreshment of all the arguments in favor of moving to more open or at least
affordable (e.g. PDF) document formats.
Any pointers/text will be appreciated.
Thanks,

I used drbd on a LAN, and know that it can theoretically work rather well
on larger distance when used as read-write on one side only. They also
have a pay-for tool to do this asyncronously called drbd proxy. This
implies using a local copy and have drbd sync it. You can choose between
three what they call Protocols to affect the perceived local latency.

Re: [YBA] sign a jar without Java?
Hi Shachar,
So far I have managed to write a C program using libarchive and the
OpenSSL libcrypto API that creates a jarfile with the exact same manifest
and .SF as jarfile does - I can reproduce the exact same MD5 or SHA1
hashes. I made my own CA and signed the JETTY.SF file but jarsigner
verification fails when it finds a DER encoding that it cannot handle in
the signature. The signature looks identical to the signature produced by
jarsigner when viewed with openssl pkcs7 -inform DER -in JETTY.RSA
-print_certs -text. I instrumented my own build of openjdk to find exactly
where the problem happens. At this point in the game I either have to find
someone who knows the secret or I am going to have to get serious about
understanding the jar verification at the binary (DER) level. AFAIK no one
has published a C/C++ jarsigner equivalent.

Not only do I NOT know how to do that, I don't even know how to verify the
signature myself. The hashes
claim to be MD5 (or whatever other standard hashing algorithm), but an MD5 of
the signed files do not
yield the same hash. I have no idea what is, in fact, signed there.
If you can calculate the has, I may be able to help you with the actual
signature, however.

I'm an computer scientist and oleh chadash , just finished ulpan bet

of a startup last year, this year I've been mostly studying Hebrew.
So now it's time to polish off my CV and further my career. I've been

was just looking at the IBM Research Labs - very interesting indeed.
However most positions seem to require an MSc. There is a definite

- I don't have one. I'm 34 and don't want to hang about forever, but
at the same time I might consider postgraduate studies if they were
really useful career-wise. Naturally, it's also too late in the year
to apply for the upcoming academic year...
I'd be interested to hear any thoughts from the list on whether it
would be a Good Idea to consider an MSc at this point, or whether I
should settle for a role where just a BSc is required, and see if I
can work with future employer to study whilst I work...

Re: OT: Postgraduate studies
Hi Antony,
If you are a computer scientist then you better get an MSc, if not a PhD
quick.
If you were a software engineer then I'd say why bother.
If you are a code hacker who writes 5,000 lines a week, then don't bother
telling anyone you even have a degree - if they find out, just say you
forgot.
It depends on how you want to bill yourself.
Now as for employers, most want you to work overtime for a few years and
then they are more generous about letting you study part-time.
Regards,

Subject: OT: Postgraduate studies
(I hope this isn't so off-topic as to cause offence.)
I'm an computer scientist and oleh chadash , just finished ulpan bet
plus. 15 years experience in the field, 1.5 years in Israel, was CTO
of a startup last year, this year I've been mostly studying Hebrew.
So now it's time to polish off my CV and further my career. I've been
browsing the main Israeli high-tech websites today, as an example I
was just looking at the IBM Research Labs - very interesting indeed.
However most positions seem to require an MSc. There is a definite
cultural difference between here and the UK in terms of second degrees
- I don't have one. I'm 34 and don't want to hang about forever, but
at the same time I might consider postgraduate studies if they were
really useful career-wise. Naturally, it's also too late in the year
to apply for the upcoming academic year...
I'd be interested to hear any thoughts from the list on whether it
would be a Good Idea to consider an MSc at this point, or whether I
should settle for a role where just a BSc is required, and see if I
can work with future employer to study whilst I work...
Antony

Beyond Stallman
Dear Friends,
As community it is time for us to look beyond Richard Stallman.
There are more important and smarter people around who are worthy of our
efforts. To wit, Nina Paley, Allison Randal, Karen Sandler, Rob Weir...
These people are a league above Stallman. Rather than waste our efforts on
Stallman we should be starting a dialogue with these other more important
folks.

Perhaps he's an hypocrite
feeble-minded-self-hating-jewish-leftists, a member of J street, or god

BLOCKING free speech! How DARE you! Have you lost your mind !?
Arguably, he alone (in concert with his Palestinian hosts), is the one
limiting free speech. Nobody here has intimated that he can't voice his views,
whatever they are, although there was some talk about expressing them in
the name of FSF. The discussion has nothing whatever to dowith free speech.
The fact is, by the way, that the right of free speech has nothing to do
with individuals at all, but is entirely a fence against government. The
government of a free country may not forbid expression of protected
speech (there are limitations to that as well). Individuals or groups are
certainly
not obligated to listen. You can't holler free speech if somebody
insists upon telling you his views that you don't want to hear. The only free-speech
issue that would arise in connection with Stallman would be if the
Government should forbid or punish him for expressing them.
The quotations above, beginning with Ad hominem and ending with Have you
lost your mind!? were written by someone who never sat in a Civics class,
and who has only the foggiest notion of what free speech actually means.
So, free speech has nothing to do with individuals? well, isn't you right of
free speech allows you to say
that I only the foggiest notion of free speech?

Karen Sandler: formly from the SLFC, now heads the Gnome Foundation.

Re: Beyond Stallman
Hi Nadav,
There is still a lot of buzz around Stallman, but in fact, the real action
is has been elsewhere for some time, despite lack of name recognition for
the players. I think that it is best to try to find the serious thinkers
in the FOSS world and invite them, wrt buzz. In fact, it might be to our
interest to invite really serious people who are unknown.

I think that if you need to open Google, Wikipedia, or LWN to find these
people, there are, regretfully, not as influencial as Richard Stallman -
whose name everyone (I assume) has heard.
Selfishly, I would considered someone to be influencial if he or she
influenced *me*, in my starting to use free software, in my starting to
write free software, or in the free software I use daily.
Richard Stallman is an obvious candidate, but we are boycotting him ;-)
Tim O'Reilly is influencial because he edits and publishes many books about
free software, and especially this one:
http://oreilly.com/catalog/opensources/book/toc.html
which had a huge effect on my own starting to write (not just use) free
software. He was also the first one to coin the new term open source.
Linus Torvals is of course super influencial.
Chris DiBona is interesting for several reasons, but among other things he
co-edited the above mentioned book, and he's Google's free software guru.
Eric Raymod is another influencial person.
Arnold Robbins, who will speak in August Penguin, maintains gawk, which is
certainly not as well known as these other people, but nevertheless will
be interesting because I use this program.
And of course there are the usual Unix suspects (Rob Pike, Brian Kernighan,
etc.), Marc Andreessen (NCSA mosaic and Netscape), Bill Joy (vi and Sun)
and many other people who influenced my computer-using life and I'd like
to hear :-)

Re: File Server for SOHO?
Hi Amichai,
I think that you would be best to tell your friend to use genuine
Microsoft Windows for the server for the following reasons:
a) He will remain your friend and will not curse you for setting up
something that he can't understand and is not motivated to understand
b) He will not be exposing the core of his business operations to the
risks of an unfamiliar technology and the risks of multiple technologies
c) He will be able to fix it himself or easily find someone who can
Instead, you should set him up an additional client workstation with
Ubuntu and show him how to use it.
Sorry for deviating from the party line, but I have gained the above
wisdom over many years of experience with small businesses.
Shabbat Shalom,

Subject: File Server for SOHO?
Hi All,
A friend of mine has a small biz with 6 PC running Windows XP Home set up as a
Workgroup. He
has a dedicated app that saves files to a shared folder on one of them, and all
other PC
access these files as clients...
This specific PC that acts as a server is dying (the hard disk is failing and
caused the PC to
crash a few times).
I am trying to sell him the idea of a Linux based File Server. The dedicated
app doesn't
care where the share is, as long as it seems as a Windows Share. I was thinking
this is a
classic SAMBA Server scenario.
I need help with the following:
1. A few selling points for the Linux based solution.
2. Which solution to implement?
2a. Ubuntu Server with SAMBA?
2b. A dedicated distro (FreeNAS or some such)
3. A way for him to see what's going on with the server, some basic admin tasks
(like
rebooting the server if it is not accessible) - some way to make them feel they
have some
control over it and it's not just a black box they cannot see or some way
to make them
drop that specific demand from their list
5. This server should also handle backups to an external USB drive and send
reports by e-mail
in case of a failure.
Thanks!
Amichai.

Re: sending mail from the command line
Hi Dan,
Indeed it looks as though your mail did in fact go out to gmail. There is
a chance that gmail silently dropped your mail in its spam filter.
You could use tcpdump (as in wireshark) on outgoing traffic to destination
port 25 to examine the traffic between your machine and the receiving
machine. Alternately you could send to another mail server that has less
opaque filtering.

And what if he just wants it? A CRM can be used for any size
organization, and is certainly easier to maintain than that list of
unconnected resources you listed.
Yes and no.
Yes, he just wants it, because most geeks want to solve problems by
installing and learning about software without regard to whether the
technology is appropriate for the application or the customer.
No, because the overhead of installation, configuration, learning curve
and maintenance of the CRM is not only much higher that maintaining a few
files, but it usually doesn't eliminate the need for those files.
The way most of us get around the CRM overhead is by *ignoring* the
overhead. We do it in our spare time because it is a hobby for us. If
you had to pay someone else to do the work you wouldn't bother with it.

Re: question about customers management webapp
Hi Hetz,
I suspect that this idea would be a misuse of technology.
Unless you have more than about 100 customers, you should be able to
organize your business around three or four OOo templates, a spreadsheet
with two or three pages, a small set of PDF documents, and a simple web
site. For billing user something like Rivhit, or outsource your billing
to a bookkeeper. That's all you need for consulting.
I would have second thoughts about hiring an IT consultant who needs a CRM
system to manage 10-20 customers ;-)

Subject: question about customers management webapp
Hi all,
I just became a freelancer (I wrote a post with some things I learned that
could be useful to
others, thats why I added the link), and I'm looking for something that I'm
quite surprised I
cannot find.
I'm looking for some customer management web app (which supports Hebrew), so
it could allow me to
issue price quotes. There are few CRM programs but these are monster solutions,
and I'm looking for
something simple: add/edit/view customer details, a catalog of products, and
a simple way to
create some page with customer name and some products, VAT and make a PDF
out of it. I can
spend few hours writing such a thing in PHP/MySQL, but it will be like
reinventing the wheel..
I'm sure that there are few people here who are freelancers, so I wonder which
solution do they
use, and which app do they recommend?
Thanks,
Hetz

Subject: A 12V *AC* power supply
Hi list,
I bought a USB connected logic analyzer for too much money (not that much).
When buying, I did a
mistake and not thought through the issues, and bought from a US supplier
without telling them this
needs to be a 220V country. As a result, I got an external power supply that is
110V, which outputs
12V AC at 1000mA (why they do not write 1A, I do not know).
To my shame, I actually bought a universal DC supply without noticing that it's
AC I need, and
started a support call with the company. They were very nice, and when we,
finally, found out the
source (I hope it is it), the guy said I could probably get by with 18VDC, but
it would strain the
capacitors (my math suggests that 15VDC is closer to the mark).
So, does anyone know where I can get a 12V AC power supply? They are not
exactly a commodity.
Thanks,
Shachar

[YBA] g++ newbie: No warn on missing method implementation?
Dear linux-il list,
g++ seems to be quite happy to compile and link a program that has a class
that includes method declarations that are not implemented, as log as
those methods are not called explicitly in the code. VS2008 seems to be
able to discover this, either at compile or link time. Any way to do this
in g++?
Thanks,

Re: [YBA] g++ newbie: No warn on missing method implementation?
Hi Shachar,
Right, right.
I also think that the VS2008 is doing something extra.
My problem is that I have a class with 70+ methods and the customer keeps
changing the specs. I need some way to verify that all of the methods
declared in the class have implementations. The most common mistake is
that I change the method name in the class but forget to change the name
in the implementation. I suppose that I could write a Perl script that
would automatically generate method calls from the class method
declarations and then watch for link errors.
Regards,
- yba

I'm not sure the VS2008 behavior is the standard. Declaring a method in a class
and not defining it
is the same offense as declaring a function and not defining it, both from
the technical and from
the conceptual perspective.
More to the point - I'm not aware of such a flag for g++. I'm not sure where
such a flag should
even come, as the compiler should never be the one to do it (how will it know
it is not defined in
some other compilation unit?), and the linker cannot (how does it know a
function was defined if
noone was using it?).

Re: [YBA] g++ newbie: No warn on missing method implementation?
Hi Shachar,
Right again. I had a bug in a macro that defined the class name. In fact
all of the methods bodies were implemented outside the class.

That would not compile. The implementation under the old name would not match
any method
declaration, and the compiler would complain.
