Hello list,

Unfortunately I can not get to this lecture, but I would really like to
hear it,
Is there anyone that goes to the lecture and can record it - I prefer a
video recording (e.g Google+ Hangout) but audio recording will suffice if
it's any trouble

Thank you,

Hi Dov,

Bank Yahav, they are the same as Bank Hapoalim (they split up, but they

them)

Re: Did anyone buy a Kaya 10 inch table from Office Depot?

[Rabin Yasharzadehe]

I really don't recommend buying those cheap China's tables, because the
lack of support and updates

but in most cases, the Host port will allow you to mount a Flash Drive (AKA
Disk-On-Key) which formatted as FAT32 (not exFAT!)
in more advanced ROM's one can find pre-build modules for NTFS (via fuse)
or to be able to add the module manually and load it using an App

In Linux i never had to install any driver for any Android device, but if
you like to use the Debug option - you need to install the ADB file
for example - on Fedora it's called - android-tools.x86_64 , this will
allow you to open shell (and other stuff) to the device

In Windows, i use Universal Naked Driver

 It has 2 USB ports on it, one marked HOST (USB type A) and a mini USB port.

 If you plug in the miniusb port to a computer running Windows using a
 regular USB cable it asks for drivers which only are available if you
 install the Google development kit.

 Anyone know exactly what the USB ports are for, and how to use them?

 It's running Android 4.1

 Thanks in advance,

 Geoff.

Re: Nook HD+ and Linux

For easy file transfer I use Airdroid over wifi

For file manager I use Total commander

There is a sshd app for android which allow you to connect using ssh.

And you can also use ADB tool to pull/push files from/to the device.

 I apologize if the question show my newbie-ness with regard to android.

 Nook prices got so low (around $150), that I bought one. But I am having
 trouble transferring files to it for using to play video.

 USB connection shows one file, an html which sends me to download an OSX
 dmg file for a mac.

 I have not used it yet with windows, so I am not sure if this is a
 solution. I prefer to not use windows if I can, and I definitely do not
 have a mac laying around.

 If I connect to a video file on a remote machine, it streams rather than
 saves it.

 If I rename it as .zip, it downloads it, but then tries to open it with
 their office suite.

 AFAIK there is no 'terminal' that would allow me to access the directory
 system and rename files, and VLC does not have an 'open file' option, which
 ignores the extension and looks at the file type.

 Any suggestions how to bypass their stupid protection, other than rooting
 the device and installing another OS? This is planned for the future, but I
 am not ready yet - I want to work within the system.

 The GRUB command prompt allows you to enter any arbitrary GRUB command
 and boot the machine however you like. So if the LiveCD contains a working
 GRUB installation, you can use the GRUB command prompt there to boot it
 like you would boot from the hard disk.

Re: Linux friendly NAS or networked drive/raid - perhaps wireless

[Rabin Yasharzadehe]

 On Sat, Oct 5, 2013 at 6:47 AM, Steve G. word...@gmail.com wrote:

 I am getting to a point that, between all the old computers I still own or
 use, the orphan hard drives from abandoned systems, and the dual boot
 laptops, I have a storage nightmare. I have photos, videos, articles,
 music, everywhere, and it is getting to the point that I can't access files
 because I don't know where they are or were, or because they are on drive
 that are no longer in use.

 So I am thinking, maybe I should get an external network drive, or raid,
 or NAS, and use it to consolidate my drive and keep all my files in one
 place from now onward.

 Any suggestions of devices, or where to look for them?

 Here is what I think it should look like:

 - OS agnostic - should play well with Linux, MacOS, Win7 or 8 (for
 future). If I can access it from tablets or smart phones (iOS or Android),
 even better.

 - if it can handle IDE drives it would be awesome - all my old drives are
 IDE , and it would be nice to continue using them.

 If not, I need a solution to connect the older drives - at least so I can
 transfer the data without taking apart an older computer and physically
 mounting each drive.

 - 2 drives (maybe more?)

 - accessible by both wired and wireless connections, if possible

 - I assume I would have to connect to the device directly to set up the
 IP, and from then on manage it remotely. If I can set the IP address
 without connecting (I remember headless servers that let you set the IP
 with a toggle on the device) life would be so much easier.

 - cheaper than dirt, or at least double digits, not triple (in dollars)

 Questions:

 1. What do I do if my wireless router has two IP networks, one for the
 wired computers and the other for the wireless (a real situation and also a
 real pain in the ass - wired computers and laptops could not reach one
 another)?

 2. Is there a simple way - or any way - to connect to the drive from
 several networks (because the cell phones have a different IP address, and
 also the wired and wireless devices might have separate IP addresses)?

 Thanks,

 Z.

Re: Linux friendly NAS or networked drive/raid - perhaps wireless

I did the math once, not worth it,

חפרתי קצת לגבי לוחות שלא זוללים הרבה חשמל ומצאתי כמה
 אבל היתה לי עכשיו שיחה ממש מעניינת עם בחור בשם יריב מאתר plonter
 הבחור לא איש שיווק אבל הוא תפר לי משהו יפיפיה מארז מעוצב ב-1500
 אני יכול לשחק טיפה עם הלוח אם ולקחת משהו חזק יותר אם צריך

 עוד משהו שיצא לבדוק, אם אני אשתמש בספק של 120W בערך העלות לשנה תהיה בערך
 350 שח
 ואז ההפרש בין QNAP 459 Pro+ II שצורך בערך 33W, למחשב רגיל יורד עד בערך
 200~ חיסכון לשנה

 אז יוצא שלקנות NAS תפור מראש יצא משהו  בערך של 5000~ שח
 והרכבה של מחשב מאפס תעלה לי גג 2000 שח

 הפרש של 3000 שקל שההחזר שלו במנות של 200 יהיה 15 שנה
 ולא נראה לי שאני יוכל להנות מ-QNAS עד 15 שנה :)

 עוד מוצר שיצא לי לבדוק הוא - HP ProLiant N36L
 העלות שלו היא בערך 1500 שח ונראה שניתן לפרמט ולהתקין עליו FREENAS

3G Modem with SMS support

[Rabin Yasharzadehe]

I am interested in buying a 3G modem to connect to some for our servers, in
order to get alerts by SMS, the idea is not to depend on the infrastructure
of the DC.

I am looking for a modem supported under Linux (RH6), If someone has
already made his survey on this matter, or have proven experience on the
subject, I'd love to hear it.

A nice feature but not required, is to be able to restart/initialize the
modem remotely if it get stuck.

Asterisk has both a Nokia (USB or Bluetooth) channel driver and
a Huawei USB channel driver. 

The Huawei driver, chan_dongle, allows you to make and receive
calls and make and receive SMS messages. 

You can send SMS messages from anything that can issue Asterisk
commands, which is basically any task that can execute a command
on the that computer. 

If you buy a Huawei dongle look for one that allows you to
connect an outside antenna. For example, my RSSI is 8 next to my
computer, but with an external antenna 10 meter cable outside on
a railing, it peaks at 24,.

We had this issue with one system of ours. It turned out that nothing
would do. Even when the box was off, it still provided power to USB and
the modem was powered on. Fun.

  
  Powered USB-hub connected to a electricity source that you can toggle
from the computer?



This is just what i thought i can do, but I had hoped it would be
possible to turn off the USB port , but it is not supported yet.

Right now I'm looking on external modems from WaveCom, which are

  In well over a year of using it, I have never had my Hauwei stick
  get stuck. YMMV. You can via a command unload the dongle module
  and reload it, which restarts the modem.
  
  Since it is USB, you can connect it to a powered hub, and turn
  power on and off by unplugging or switching the hub.
  
  I don't know what the price of the WaveCom is, and your budget,
  but someone was selling a used, with a guarentee that it works and
  an external antenna E169 for $30. I almost bought it myself it was
  such a good deal. :-)

Re: linux system acting as access point/router?

[Rabin Yasharzadehe]

You will need a wireless device which supports AP mode (Access Point (AP)
infrastructure mode), you can check if your current device supports it
using the `iw list` command:

# iw list
 ...
 Supported interface modes:
  * IBSS
  * managed
  * AP
  * AP/VLAN
  * monitor
  * mesh point
 ...


​If your device have support for AP mode you can use hostapd and create an
Access Point for your other machines to use.

 power is out, and they are all down, I want to start a network on the
 laptop and forward the internet connection from a USB cellular modem to
 various users here.

 Sort of using a cell phone with wifi tethering, but instead using a laptop.

 I was able to do it easily with Windows. Microsoft added it to Windows 7
 and someone wrote a GUI for it.

 I would prefer to have the laptop running Linux.

 An Ad Hoc network does not work, my Android devices do not see them.

 I am running Zorin 7, which is an Ubuntu derivative.

Re: Does anyone use MATE (Gnome 2 fork)?

[Rabin Yasharzadehe]

I'm using it for some time now on Fedora, each new release I try and use
Gnome 3 - but I always go back to using MATE+Compiz (there is even a Fedora
spin for that)
I tried Xfce , as I like my desktop light and snappy, but I had problems
with the keyboard.

I really recommend it.

 We only use the online banking services from within our home network which

 The real diference between using a mobile phone and using a laptop is that
 first hop, from the device to the tower. I know that on the laptop it is
 secure, there are no man in the middle attacks since I control every device
 on the network (and I'm assuming that from my router to the bank there is
 no MiM attack either, probably a safe assumption). But what about from the
 phone to the tower? Are all communications between the phone and the tower
 encrypted? Are some devices and/or carriers more secure than others? Are
 some bank's apps more secure than others? How about just using the web
 interface from a browser?
 I know that this is only vaguely Linux-related, but I'm sure the people
 here have the experience, knowledge and insight to help me out.

I do not trust the cellular companies ROM's - so I always switch to an open

There was a time no long ago where each ROM (even iPhone's) came with a

As for trusting the cellular providers ... You don't have much a choice ...

 I trust my computers, I trust my network.
 I've never had an Android phone before so I don't know whether to trust
 the platform or the 3/4G network (since I've never used that either).
 So my question really boils down to: do YOU (plural) trust your Android
 handset and cellular provider? Which provider do you trust? Which don't you
 trust? (We may need to renegotiate cellular plans soon anyway...) What did
 you do to your handset to make you trust it more?

Re: Chinese KitKat

[Rabin Yasharzadehe]

After trying to fix several cheep/Chinese tablets/phones for my family and
friends, i took an oath to never buy a cheap Tablet/Phone ever - just
because there is no support.

What I can tell you from my experience with this kind of devices, is that
you can't trust the name - use an application like Elixer to find all the
information you can on the device hardware
most of the time, the CPU will be a MediaTek cpu (a cheep one not the 8
core the made it to the news),
(most of this Chinese devices are created the same way, and rebranded for
who ever pay/distribute them)

Then you need to Google and find a forum (not XDA) which talk about this
device, and if you lucky some one else compiled a vanilla Android for it.
from my experience i never was so lucky, because there are some drivers
compatibles issues, and some times you need a custom kernel to boot a newer
version of android on this devices.

As for USB OTG and other devices, you probably will need to compile the
modules (or find them online) and push then to the device manually, and
then use the terminal to modprobe them.

 It's running Android 4.1, which just upgraded itself (no details on what
 was upgraded were given), but has no search for upgrades option.

 Is it possible to upgrade to a generic version of KitKat? One of the
 reasons I would like to update it is that the operating system is
 customized for the hardware. It has a regular type A USB port for OTG
 devices, but only has drivers for USB storage. I want to add bluetooth
 (keyboard, headset), USB headset and an SDR dongle. :-)

 If so how? Is there an English step by step tutorial?

 * Command interface, simple
 * Time file simple to parse and report
 * Can be front ended by UMENU or other menu software
 * Software is simple: Easily changed to your own needs
 * Survives reboots

 Cons:
 * Command interface, difficult for some users
 * Reports must be written in software, no specific reporting facility
 * Cannot track concurrent tasks (but for one person, wouldn't that be
   cheating anyway?)

 Thanks, I doubt that I will be building anything myself anymore.

 This would not do anyway, it is for programming PIC chips, I want EPROMS.
 PIC chips are processors with read only memory on the chip. EPROMS are
 1970's technology, read only memory chips that can be programmed with a
 high enough voltage, and then erased with ultra-violet light. They were a
 big step above PROMs which were programed one time only by literally
 burning the silicon away.

 EPROMs are still made today, in fact while you can buy them for about $1
 each pulled from old equipment in China, you can buy electronically
 identical  current production ones in modern packages, they are about $40
 each.

 The generic burners are cheap enough, under $50 including postage on eBay,
 but none of them have software that actually works under 64 bit Windows.
 Since I also have a computer running linux on my desktop, I thought I would
 look there.

I was on Rami-Levi at that time, and i didn't have this problem, and I was
satisfied with the Internet speed most of the time (tethering  mobile).

Then we both move (most of 2012-2013) to YouPhone - with better reception,
same Internet performance in my case.
And when the deal was over, and both switched back to Rami-Levi (less
expensive 50 NIS/mo for a year) , And one again I have bad reception in

 Golan seems to be the only real company, willing to invest in their own

 Comparing prices and plans is easy, and they all more or less offer

 So, my question is: what kind of experience have you had with your cell
 phone service provider? (Any of them, but preferably I'd like to hear about
 the new companies).
 I've heard that text messages on Golan are unreliable (the sender is on
 Golan, I lack sufficient data about the receivers). Someone told me that
 her messages will be received at the other end with no guarantees
 whatsoever. Sometimes they'd be received normally, sometimes after a large
 delay (hours, days, in one case weeks) and often they are received jumbled
 (parts of two messages mashed together to form something incoherent or
 embarrassing). Has anybody else had this experience? Or similar experiences?

 This suggests that it is indeed googlebot, why should they put GCE on
 googlebot hosts, way too high a risk of resulting in blocked bots.
 I would guess that either
 - They were testing a new crawler that is messing up (likely, but less I

Re: partly OT: notification of url when connecting to open wifi

I think it's the same/some implementation of Google chrome to check if you
are behind a proxy and have access to the internet.

  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: Looking for a performance/health monitoring and alerting solution

[Rabin Yasharzadehe]

I can recommend Zabbix, I was never used it on a large network (~30 server
most), but i was happy with it.

- you can set the monitoring interval for each item (from 1s - days)
- samples are stored in the DB, and graphs are plotted only when you need
them
- have a build in support for SMS and Jabber message alerts.
- works with agent, but also works with SNMP and scripts you can writes.

note that you'll need to provide enough storage for it.
(i think they have the formula or a calculator in there website, which you
can use to calculate the storage you'll need )

 disk space, etc). Things I'm interested in (in parentheses - how I track
 them at the moment. Note shinken is a nagios-compatible thing).

 Free disk space (shinken)
 Server load (shinken)
 Debian package and security updates  (shinken)
 NTP drift (shinken)
 Service ping/reply time (shinken)
 Upload/download rates per interface (mrtg)
 Temperatures (sensord, hddtemp)
 Security logs, warning and alerts e.g. fail2ban, auth.log (rsync of log
 files)

 I have a few tens of servers to monitor, which I would like to do with one
 software and one console. Those servers are not all physically on the same
 network, nor do they have a VPN (so, no UDP) but tcp and ssh are mostly
 reliable even though they are low bandwidth.

 Please note that shinken (much like nagios) doesn't really give a good
 visible history of things it measures - only alerts; Also, it can't really
 sample things every few seconds - the lowest reasonable update interval
 (given shinken's architecture) is ~5 minutes for the things it measures
 above.

 Any recommendations?

 Thanks in advance,

Most of what I wrote against nagios is relevant to Zabbix as well - central

Aagreed, but you can setup a zabbix proxy servers to collect the data, and
one server to store it and graph it, distributing the load of a single

 ​I tried .forward, .procmail, etc., but whatever happens there is an error
 invoking email_in.pl.

 No problem with mail though.

 My current setup includes:

 In /etc/aliases I have

 bugs:   |/var/www/bugzilla/email_in.pl

 (obviously, postalias has been run and postfix has been restarted).


 # ls -l /var/www/bugzilla/email_in.pl
 -rwxr-xr-x 1 root www-data 21820 2013-05-23 19:02 /var/www/bugzilla/

 (I made the file world-readable and world-executable out of desperation).

 # grep www-data /etc/group
 www-data:x:33:postfix,bugs

 ​(i.e., both user postfix and user bugs are members of the www-data group
 that owns the bugzilla installation).​


 ​Whenever I send an email to user bugs@therightaddress I see in
 /var/log/mail.log:

 ​
 Jun 22 14:23:43

 ​This happens with or without user bugs (i.e., whether bugs is just a mail
 alias or there is a shell user named bugs).
 ​

 ​So, it looks like mail gets delivered to the right alias and the right
 processing is attempted, but something prevents email_in.pl to be
 invoked, and I have no idea what. Needless to say, mails do not appear
 where I expect them in Bugzilla.

 I googled extensively, and I think I tried every possible delivery recipe.
 it seems that the particular recipe is not the problem - for some reason
 email_in.pl cannot be run. I have not seen this particular error while
 googling.

 The server is old, I inherited it, and I cannot re-install it for various
 reasons (at least i am *extremely* reluctant to).

 Has anyone seen anything like this? ​
 ​Any ideas?​
 ​ What am I missing?​

 If modifying an _image_ is your purpose, and you want to avoid
 distributing the whole image, and you can do that 'offline' (i.e. you have
 two partitions, one active, second for upgrade and boot from - so you don't
 touch a system with a mounted filesystem), and you have your way to manage
 this versioning (i.e. you know for a fact what the previous image blob is,
 so what you need is really the blocks that changed from it) - maybe take a
 look at http://xdelta.org/

(finding drivers for Win7 64bit was a bitch back then), anyway, at the end
it worked i preferred to record the caste to a uncompressed AVI file (~20G
per 3 hours) and not use the direct MPEG2 encoder.

Then I use VirtualDub to apply some filters to optimize the picture quality
(CROP few lines the bottom, some soft bluing i think and one more for the
lines which i can't recall right now), and used DivX for compressing the
video and mp3 for the audio (and I used a single pass compression).

then i used the device on my Linux machine (F17 i think back then), and it
worked, seems like my first device had a hardware problem.

Bottom line (for me) was, not all silicon chips created the same, and be
careful when buying cheap converters.

 Thanks, but I was looking for a more personal experience. I found devices
 as cheap as $5 on Chinese sites, some of them with free shipping. I'm
 looking for success or failure stories. What the setup was, how easy or
 hard it was to use, what the final results are like.

 Hi Linux-IL members,

 I'm using bidiv to read Hebrew in mutt.

 It works ok with reading Hebrew messages, but not when reading the
 subject headers, which still show the Hebrew backwards.

 So I wrote the following script caled bidi_index to enable reading of
 Hebrew in the subjects:

 echo $@  /tmp/index.out  bidiv /tmp/index.out

 and I added to .muttrc the following:

 set index_format = /home/alan/.mutt/bidi_index %D %-15.15L   %s (%Z) |

 (I tried piping the text directly to bidiv, but I got an error, so I write
 to a temp file, and I have my script read the temp file.)

 Mutt shows the Hebrew properly, but it creates a new problem. The minimum
 length for the sender's name no longer works. My setting is for a minimum
 length of 15 chars, as in the index_format setting I quoted above, but if
 the name is less than 15 chars, mutt does not pad the rest of the 15 chars
 with blanks.

 This problem doesn't exist if I don't pipe to my script.

 Does anyone know how to fix with this problem, or does anyone have an
 alternative way of displaying Hebrew in mutt (which you've checked gets
 around this problem)?

 I'm using Mutt 1.5.21 (2010-09-15) on a gnome-terminal in Ubuntu 12.04,
 with LC_ALL=en_US.utf8.

 Thanks,
 Alan

Re: Parsing compilation errors and automatic resolving

[Rabin Yasharzadehe]

I'm not much of a developer, but if the application you are trying to
compile is a C/C++ program (i also used this method to find Perl missing
library's), you can grep through all the .C/.h files for the '#include'
lines and extract the needed library's which are needed for the application
to run. then you can use the distro manager to locate the packages which
provides the necessary files.

In Fedora i use yum/dnf provides */xyz.h and on Debian based distro you
have apt-file search

 Are there utility, which parses errors and proposes obvious solutions?

 For example, following code proposes to add missing library to LDFLAGS:

In my case for each new Chrome session I install `ublock origin` , which
allow you to backup your setting to a file.
but you may find where the plugin save it configuration and re-apply them
after chrome start.

I also now about `proxy switchysharp` which allow you to export it
configurations.

Re: portable encypted filesystem

[Rabin Yasharzadehe]

VeraCrypt is fork which continue the TrueCrypt legacy,
TrueCrypt had some audit (crowd source founded) on the encryption part
(algorithm and stuff), the boot loader,  and the windows kernel driver
(IIRC).

they found few  vulnerabilities at first (3 I think), but nothing critical,
and they were patched in VeraCrypt.

next was a bug in the windows driver which allowed a user/process to gain
SYSTEM privileges.
which also was patched.

Re: persistent private browsing ?

[Rabin Yasharzadehe]

That's right, Incognito/Privet Browsing mode share the same session.
this is why you need to create a new profile for each case.

Chrome & Firefox can be configure to run with pre-installed addons,
but you may need to configure them if needed.
but there some extension which allow you to export there settings (so maybe
you can automate the import ?).

Re: Summary: Which Linux distribution is stable yet up-to-date

[Rabin Yasharzadehe]

I never said Fedora is unstable!
Arch can be unstable because it try to be on the bleeding edge,

Fedora is "bleeding edge" as far as a stable release can be.
and it has a short release/support cycle.

Re: How to search Linux Kernel changelogs? (USB disconnect problem)

[Rabin Yasharzadehe]

I had a "problem" with tlp & powertop when i tried to used this tools to
configure my system (laptop) to conserve energy,
I enabled all tunable options, and I started to experience smiler symptom
as you describe above,
where my mouse will suddenly stop working, and my disk was contently
sniping down and that created lags when I was switching tabs in the browser.

Re: ביצוע תיאום מס באתר המיסים

[Rabin Yasharzadehe]

Open the `Developer Console` and goto the network tab,
clean the log before pressing the "חשב" button, this should give a better
overview what really is happening.

- also try and change/fake the user-agent string and see if that help in
any why.
- my guess is that there is some JS not hooking.

Re: Chromium homepage problem - OR - Have I been hacked?

[Rabin Yasharzadehe]

try disabling all your extension,
some extensions developers will sell there extensions to some 3rd party
 which will then embed some nasty stuff inside of them.

worst case, you can try and reset your chrome profile.

Re: How can the total memory consumption rise without top/htop displaying increasing processes' use?

[Rabin Yasharzadehe]

Maybe it's writing/logging something to a tmpfs folder (like /tmp)

Re: Hebrew monospace font

[Rabin Yasharzadehe]

I also was looking for a Hebrew mono spaced font, but didn't found any one
i like ,

I was looking for a why to merge the Hebrew glyphs from GNU-Mono into
Anka/Code but using fontforge,
but it didn't work for me, so i gave up.

But some applications/editor's/IDE's support the option to set a secondary
font as fallback
- this allow me to set the default to the one i like (currently it
Anka/Code and Source Code Pro)
- and use GNU Mono as my fallback font

Re: Raspberry PI - analog sensors with Arduino

[Rabin Yasharzadehe]

אין מידע טכני על הערכה עצמה (יש רק רשימה של המודולים), אבל ממה שאני רואה
מהתמונה השניה מדובר ברכיבים שמורכבים על לוחות PCB שיש לו פינים שאמורים להקל
עליך לחבר את ה"מודול" לתוך מטריצה מחוררת
<http://skpang.co.uk/catalog/images/raspberrypi/kits/IMG_0003.jpg> ואז אתה
רק צריך לגשר מה-BOARD של ה-RPI לתבנית.

שים לב גם שה-RPI לא אמור לתת לך הרבה זרם ביציאה של הפינים , אז אל תנסה
להשתמש בו כדי לדחוף התקנים טובענים שצורכים הרבה זרם (ממסרים , מנועים וכ"ד)
אחרת זה יהרוס לך את היציאות של ה-RPI (בשביל למתג דברים כאלה אתה תצתרך סוג
של דוחף זרם\טרנזיסטור)

-- 
בגדול נראה לי שהערכה תעבוד ,
מהתעוד של ה-GPIO של ה-RPI אני רואה שהוא עובד על מתחים של 5V ו-3.3, שזה אמור
להספיק לך לרוב הדברים שאני רואה שם בערכה בלי בעיה.
אבל כדי להיות בטוח הייתי מבקש מהספק שישלח לך DATASHEET פרטני יותר של כל
הרכיבים שיש שם בערכה.

Re: Raspberry PI - analog sensors with Arduino

[Rabin Yasharzadehe]

קח בחשבון שיש הבדל מהותי בין שימוש בצ'יפים נטו לבין מודולים מוכנים,
לרוב מודולים יעשו לך את העבודה הקשה של התממשקות עם ה-CHIP וגם קינפוג ברמת
החיווט!
כמו כן גם יחשפו לך את המידע על פרוטוקול סיריאלי פשוט כמו RS232, בלי שתצתרך
להמיר אותו.

אם אתה לוקח ADC למשל ומנסה להשתמש בו AS-IS אתה צריך לעבור על ה-DATASHEET
שלו כדי להבין כיצד להביא אותו למצב עבודה.
ולהבין כיצד לבצע איתו דגימות וכיצד לתרגם את התשובה שלו לערך עשרוני.

also make sure your repos in the `/etc/yum.repo.d/` folder are enabled and

some VPS provider will change the url's in this files to point to there

Mapping a (lagcy) PHP application

[Rabin Yasharzadehe]

Hello everyone,

I inherited a legacy application/code which was originally written in PHP4,
and letter on was "upgraded" to PHP5.

the code is (mostly) a collection of individual pages which are stitched
some how together to form a working web-application.

the code base is quite big and I'm looking for a tool which can create some
sort of a (visual) work-flow view of the code, just so I could get a
overview of the application.

I googled a bit and found a tool called phpCallGraph which won't run and it
seems is not minted any more.

Some one on stackoverflow

suggested to use xdebug profiling option and visualize the result with
KCacheGrind, but it didn't give me what is hopping for - a workflow.

Do anyone have any suggestion for a tool which can help me to get a
work-flow for the application ?

Thanks in advance

Re: Advice on lightweight laptops for Linux (of course)

[Rabin Yasharzadehe]

My 2c for this discussion is ,

*STAY AWAY FROM HYBRID DISPLAYS !!! (aka Optimus or any other
implementation) *

The current state is disaster, with some minimal support.
Only recently Fedora (25) took it as priority to support hybrid graphics
cards out of the box (in Gnome3 only).
and even then only with nouveau driver.

Stick with Intel !

Also check for multi display support with Linux when using a Dockstation.

[Rabin Yasharzadehe]

I came a cross this page, others who are looking for new Linux laptop my
find it useful

https://www.slant.co/topics/1184/~laptops-for-linux

my 2c on the matter,

Re: OT: Israeli domain names

[Rabin Yasharzadehe]

Marketing!

- you can register for 1$ (inc 0.18$ fee for ICANN) but the renewal cost
will be much higher (~15$) "שיטת מצליח".
- .com/.net domain name space are crowded, go find a nice short name in
them, so not a good compare, check other CC TLD's.
- very cheap cost will flood the domain space with domain trolls which will
buy any combination just in case
- 50 NIS is not that high compare to all the rest -- e.g -
https://www.hover.com/domains/results?q=troll-hunter-co-il

Re: Internet recommendations

[Rabin Yasharzadehe]

I can't recommend XPhone, I tried them just after the "רפורמה הסיטונאית"
started, and my VPN connections  were dropping constantly, I retuned to BBL
after 2 days, and I'm with them ever since. over the past 5 years i think i
had one issue with them, it was seems they were hijacking DNS traffic, my
router is configured to use Google Public DNS servers (8.8.8.8) and so all
my machines in the LAN, but some direct query's were failing (or not
returning a consistent result), so eventually after having a long
conversation with the LEVEL1 and then LEVEL2 support I find out that they
enabled some "CyberWall" service on my account, so I requested to removed
it, and I have no problems ever since.

my 2c.

Just move to the cheapest registrar (Box as of this moment) and use
cloudflare to manage your zone.
never had a problem, never called there support service.

Re: Help configuring Multiboot from ISOs

my 2c for this thread,

- when I created my multi-boot USB I had to defrag the ISO after copying

- I used a simple tool like -

Re: Smart home/electricity open standard

[Rabin Yasharzadehe]

There are many implementation and non of them are open standard (iirc)
e.g - https://www.postscapes.com/internet-of-things-protocols/

If you looking to start smart home project, you should probably start with
the server
which will manage and will the intermediate for all protocols and devices
-- one of them call OpenHAB <https://www.openhab.org/>

some devices will require a firmware flashing to make them to work with
your "cloud" and not the vendor.

one popular and cheep devices to start with are the Sonoff switches.

Re: Smart home/electricity open standard

[Rabin Yasharzadehe]

Just like many I have a dream to "wire" my house with smart devices to
control (and monitor) every aspect,
but unfortunately I didn't have the time to implement any of it (yet)

but I keep my eyes open on the matter and I follow the HackADay blog to
learn about new stuff,
this is how I came across the sonoff devices which where the first devices
I purchase because the option to reprogram there firmware
and avoid the vendor lock problem which most of this devices have.

The OpenHAB froums are also a great place to find devices which work
seamlessly with OpenHAB and find other hardware recommendation.

Re: ZFS on Linux (Was: Corrupt file system)

[Rabin Yasharzadehe]

ZFS is not "native" Linux fs, it was ported from Solaris & BSD OS's,
you can read more about it in the history section of ZFS wiki page
.

- FreeNAS use it for the NAS storage pool,
- Ubuntu/Canoncial started to integrate it with version 16.04 (IIRC)
- and I also tried it on my laptop with Fedora (which some time's breaks
because of the frequent Kernel upgrades)

Re: Open Source Physical Access Control Solutions in Israel?

[Rabin Yasharzadehe]

I did some research about this some time ago,
and I found out you can use a basic/cheap RFID reader + RPi to achieve this,
my problem was that the cheap RFID reader i bought didn't come with any
documentation
and I only had a simple windows application which can do 3 actions Single
Read/Single write/reading in a loop
the driver was just a simple USB-2-SERIAL (FTDI) driver
and the application communicated via serial interface.
opening a serial-monitoring tool I found the command for each action.
... but this is where I stopped working on it.

but you can definitely make it a DIY project with the kids
you will also require to buy a electric lock and a relay (the RPi can't
drive/operate the lock directly)

Re: ZFS on Linux (Was: Corrupt file system)

[Rabin Yasharzadehe]

I haven't tried it with Ubuntu, but since Ubuntu is trying to reach the
corporate world,
and they are the first distro to support ZFS,
I guess they will ensure you do not get A broken module,
and so I expect it to be A more smoothly experience.

PS. even with Fedora, it only happen to me once, that the kernel was ahead
of the package in the ZFS repo, and the package didn't build.
and ever since I just check the github issue page before a major upgrade
(eg. from F25->F26), to make sure there is no problem and there is A repo
ready for the new release.

but even if the build will fail for a new kernel, that only limit you from
using the new kernel to access the data, you can still boot with the older
kernel which the module was successfully compiled on it.

Re: rom for samsung note 5

[Rabin Yasharzadehe]

I didn't test LineageOS for Note devices, IIRC you will lose most of the
pen functionality.

you can flash an up2date rom from SamMobile with odin,
if you really paranoid you can use the repartition option which will erase
all the emmc and recreate the partition table from scratch (but be careful
with this!)

With Mozilla retiring there old API for building extension and switching to

my old trusty extension DownThemAll! will stop working, so I'm looking for
alternatives,

I tried uGet and it was mostly OK, but there also FDM which is opensourced
but no port for Linux yet, the developers are now looking to build there
rodemap and a native Linux client is on the chapter.

so if you like to promote this initiative,
take 3 sec to vote this up in this goolge form

Re: Distro recommendation

[Rabin Yasharzadehe]

I like to go with Fedora MATE spin as I find it resource friendly.
and I use compiz as my window manager to have a very robust features and
some eye candy features as well.

Fedora move fast and have a short release cycle (6 month),
so having to deal with new stuff each 6 month can be a burden for someone
how just want his computer to work.
in that case I'll recommend a distro which is based on Ubuntu LTS e,g
Ubuntu MATE.

MATE desktop dose not support HiDPI display yet, unlike KDE and Gnome3
but if you prefer to use KDE, both Fedoa and Ubuntu have a spin of it.

there is also KDE neon which uses a stable base of the OS (Ubuntu LTS IIRC),
and all the KDE stuff are coming directly from upstream (rolling)

Re: איך לשלוח מסות של דואר

[Rabin Yasharzadehe]

one things to note about this services is that if the client side use
postgray/graylisting to "filter" incoming mail,
this mails can arrive after several hours. because for each 4xx/soft-fail
attempt they will try to send the mail from another host/ip which will also
be soft-block.

i have this problem with several services like this.
and I had to white-list them on my mail servers.

but that is a client side problem and not Lior's, but you should be aware

Re: VDSL modem recommendation

[Rabin Yasharzadehe]

About TD-W9980, I have it, and I was happy with at first, but not so much
any more,
TP-LINK dose not publish any fimware updates for it, and the WRT support is
defiantly not for common users.

I also think that having a modem even as closed source and not WRT
supported is not a biggie if you're going to use it in bridge mode.

Re: Server load spike debugging

[Rabin Yasharzadehe]

You can set a monitoring (or even just a script)
to trigger (e.g when cpu usage > 50%) a profile recording for few secs
and then you can inspect them with a tool like FlameScope

which will allow you do dig deeper into the stack and understand where is
the problem is coming from.
