Re: [linux] 5.25" floppy reading
You can get hardware to use with a bare floppy drive. I don't know how good the hardware is. https://github.com/keirf/greaseweazle The software is free. The is a link to vendors of the hardware. Total cost of a setup might be around $300 Canadian. Ian G. On Mon, Jan 15, 2024 at 1:29 PM Nash JC - NCF wrote: > The subject is the topic.

Re: [linux] 5.25" floppy reading
I googled "5.25 floppy drive" and got several drives. But they are bare drives and you would have to make sure you got a 1.2 MB drive, which can also read 360K. You would still have to find a 20th Century PC and a flat cable and install an older linux. Or you could try to find an NEC u765 floppy controller chip with documentation and try to run the chip from an Arduino. You don't need to read an MS-DOS file system on the floppy, you can copy the raw disk to a linux file and mount the file as an MS-DOS file system. A hell of a lot of work to read a few floppies. I did see a ready-to-go USB 5.24. floppy system that mounted as a USB mass storage device but that was at least 10 years ago. Ian G.

[linux] reading Hollerith cards - was 5.25" floppy reading

Those should be doable, Just scan them in using a dark background so that the holes are visible and use some image-processing software to pull off the data. Way easier than trying to read the magnetic bits on the surface of a 5.25 floppy disk! Anecdote: As teens, a friend and I got a camera and Porta-Pak through the NFB "Challenge for Change" programme out of Montréal. To splice helical scan video tape without any glitches, you had to be able to "see" the timing track on the magnetic tape, so we had some magic solution (carbon tetrachoride?) that we could wipe on the tape that had super-fine magnetic particles suspended in it and when dry would show the location of the timing track pulses. That let us cut the tape in the right place and ensure that the timing tracks of the two pieces lined up properly. Alas, because it's helical scan, the usual tape splices were a one-second "wipe" that went from the scene on the first tape to the scene on the second. (It took about a second or so for the splice to migrate from one side of the spinning tape heads to the other side.) We wanted a "jump" cut that didn't have this wipe, so we would find the splice point, tension the tape against the spinning heads so that the heads would polish the tape along the helical track, and then we would cut along that helical track to make our splice. The diagonal splices were maybe six inches long or more, but they worked! -- | Ian! D.

Re: [linux] December 7th Meeting announcement
I would like to submit three recent scripts, which I wrote to deal with
ebook difficulties on my Victor Reader ( a "talking book" reader with
text-to-voice capability).
heading-numbers.awk makes a HTML page more readable in my Victor Reader. A
HTML page works as well as an ePub or DAISY book, but often does not have
heading numbers. The absence of heading numbers makes it difficult to
navigate a very long page via hearing, because you don't know where you are
in the file. This awk program puts multilevel heading numbers at the start
of every heading. The victor Reader can be set to jump from one heading to
another at any level from 1 to 6, allowing me to quickly zero in on the
part of the page I want.
I wrote the other two scripts to troubleshoot a problem where my Victor
Reader would not jump to some of the headings in the ePub,
epubcheck.sh runs the W3C ePub Validator. It is easy to run the validator
correctly but the script allows me to park the package in a subdirectory of
the bin directory and run the validator with a simple command that is on my
PATH. The validator showed that my problem ebook was a valid ePub 2.0.1
file.
html-headings.awk
<https://mail.google.com/mail/u/0?ui=2=e676b26630=0.2=msg-a:r2437192347788727639=att=safe=f_lpu7k5tg1>
extracts
headings from an HTML or ePub file. I unzipped the ePub file to and
empty directory and rand the command
html-headings.awk
<https://mail.google.com/mail/u/0?ui=2=e676b26630=0.2=msg-a:r2437192347788727639=att=safe=f_lpu7k5tg1>
*.html > all-headings.txt
The command produced a list of 272 headings, one to a line.
I looked at the headings and CSS file, could not see a reason for the
behaviour and submitted a report to the manufacturer.
Both AWK programs use a feature of AWK to make the job easy: the record
separators (RS and ORS, normally both are line-ends) are arbitrary,
Changing the record separators to '<' places every tag at the beginning of
a line, making it easy to identify the tags you want to work with.

Re: [linux] Linux-Ottawa / NCF collaboration
I think Alayne has a point about requiring NCF membership, but I think a bit of discussion with Shelley Robinson would lead to a solution. I worked as a volunteer at NCF until my vision problems caught up with me. During that time I found that Ms. Robinsion is quite good at dealing with problems that combine a number of technical and no-technical issues. I would like to participate in a joint venture between OCLUG and NCF, perhaps by writing some of the documentation mentioned in this thread. ian https://web.ncf.ca/am125/ https://web.ncf.ca/iegorman/

Re: Keeping the lights on (was Re: [linux] Result of the OCLUG motion to dissolve)
In reference to "Keeping the lights on", I would be willing to kick in some bucks. I live in Perth, an hour west of Ottawa, and am glad not to have to drive in to attend meetings. The savings in gas/parking and convenience are worth it for me. Many moons ago I would drive home from work (in Kanata) have dinner with the family then drive back in (Centrepoint) attend a meeting then drive home again. After a long hiatus, re-joining the group was very nice. Different people, but still going. I would not want to see it end for lack of a few dollars to support the bare minimum of supporting infrastructure. I pledge $60, about the cost a tank of gas, which I don't have to spend getting to meetings :-) Cheers, Ian M.

Hi all, Ian MacWilliam here. Here being Perth. I really appreciate the ability to remotely join in without having to drive in and try to find parking, the building, the room, etc. It's been a long time since any of my kids attended Ottawa U and much has changed, not to mention Ottawa construction (or the price of gas). So, will the linux-ottawa.org website be updated with a meeting announcement and jitsi link? Thanks, Ian M. P.S. While you are not on your smart phone, I suggest reading something by Jaron Lanier.

Re: [linux] Fwd: Home automation and concept art
Yes please to Linux Home Automation. I have recently purchased a Hubitat and a few ZWave devices: - a pair of Aeotec current sensors in my house circuit breaker panel - Honeywell thermostat (does not call home to Honeywell) - Aeotec temperature/humidity sensor - HomeSeer floodlight sensor I'd love to have coding access to these devices. I have my eye on the WiFi IoTaWatt current sensor unit with 14 sensors instead of 2: $293.30 USD plus $45 delivery https://stuff.iotawatt.com/cart/ On Sat, Aug 27, 2022 at 08:22:30AM -0400, Richard Guy Briggs wrote: > On 2022-08-27 02:10, Dmitriy Korovkin wrote: > > As for the general, if there is an interest in OCLUG to OpenSource in home > > automation, we could run a discussion at one of the meetings.

None of the above is needed if you only want the HOME directory of the person running the script. All that work is already done for you and sitting in your $HOME environment variable.

[linux] DHCP lease renewal misbehaviour on Distributel/Rogers
f eth2 were not my default route, the packet would go out my default route, not out eth2, and be ignored. Not good.) This unicast DHCPREQUEST to the DHCP server at 7.127.0.166 gets no reply from Distributel/Rogers. Because my dhclient uses the default "backoff-cutoff" setting of fifteen seconds, my computer repeats the DHCPREQUEST unicast over and over approximately every 9-23 seconds, and it never gets a reply. It repeats many thousands of times, until eventually DHCP protocol time "T2" is reached. At time "T2" my computer abandons the unicast and does a broadcast DHCPREQUEST. My computer immediately gets a reply from the "other" DHCP server that gave it the DHCP address in the first place: dhclient: DHCPREQUEST of 216.48.162.78 on eth2 to 255.255.255.255 dhclient: DHCPACK of 216.48.162.78 from 209.148.134.201 This reply also contains the wrong DHCP Server Identifier 7.127.0.166, and wrong MTU, just as it did before. This lease lasts until it is again time for renewal, at which point thousands of unicast DHCPREQUEST packets are again generated and ignored until eventually time "T2" arrives and the broadcast address is used successfully. Repeat, repeat, repeat. Just as an experiment, I over-rode the incorrectly supplied DHCP server 7.127.0.166 and made my computer send a unicast DHCPREQUEST to the DHCP server actually doing the offering at 209.148.134.201. That had no effect; the unicast DHCPREQUEST of 216.48.162.78 on eth2 to 209.148.134.201 is also ignored and produces no response. After thousands of failed unicast DHCPREQUESTs, my computer abandons the unicast and switches to use the broadcast address, which immediately works, with the DHCPACK coming from 209.148.134.201 but still containing the invalid server-id 7.127.0.166 and invalid MTU 576. A packet from tcpdump: 08:42:37.499402 00:17:10:93:5d:91 > 70:88:6b:85:ab:81, ethertype IPv4 (0x0800), length 342: (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 328) 209.148.134.201.67 > 216.48.162.85.68: [udp sum ok] BOOTP/DHCP, Reply, length 300, xid 0x5a87300e, Flags [none] (0x) Your-IP 216.48.162.85 Gateway-IP 7.127.0.166 Client-Ethernet-Address 70:88:6b:85:ab:81 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: ACK Server-ID Option 54, length 4: 7.127.0.166 Lease-Time Option 51, length 4: 150722 Subnet-Mask Option 1, length 4: 255.255.255.224 RN Option 58, length 4: 75361 BR Option 28, length 4: 255.255.255.255 MTU Option 26, length 2: 576 Default-Gateway Option 3, length 4: 216.48.162.65 There are multiple problems here: 1. Do not assume that I have only one network interface. The DHCP server must have an address on the network assigned to my interface so that unicast DHCPREQUEST packets are correctly routed out that interface and not out some other default interface. (Lucky for me, I use eth2 as my default interface so the unicast packets do go out correctly.) 2. Fix the DHCP server to respond to unicast DHCPREQUEST packets, as documented in the DHCP protocol. (As a work-around to avoid thousands of ignored DHCPREQUEST unicast packets being sent between T1 and T2, I changed the "backoff-cutoff" setting in /etc/dhcp/dhclient.conf to 3600 seconds instead of the default 15. Now only a few dozen unicast DHCPREQUEST packets are generated and ignored, instead of thousands.) 3. Fix the MTU to be 1500, not 576. (My machine apparently ignores the MTU supplied by DHCP, so in practice this isn't a problem.) Is anyone else seeing this behaviour on their ISP? Rumour has it that Windows machines never send unicast DHCPREQUEST packets; they only use the broadcast version, so they never see this "ignore unicast" problem. Can someone with Windows confirm this? -- | Ian! D.

Try this: $ man rsync [...] -@, --modify-window=NUM set the accuracy for mod-time comparisons When comparing two timestamps, rsync treats the timestamps as being equal if they differ by no more than the modify-window value. The default is 0, which matches just integer seconds. If you specify a negative value (and the receiver is at least version 3.1.3) then nanoseconds will also be taken into account. Specifying 1 is useful for copies to/from MS Windows FAT filesystems, because FAT represents times with a 2-second reso‐ lution (allowing times to differ from the original by up to 1 second).

Mailing lists, by their very nature, are bulk email, which is hard to distinguish from spam. The linux list does not put the name of the recipient in the To field.

[linux] anyone using a privacy-protecting cell phone
Hello Linux hive-mind - A non-tech friend is trying to get out from under Apple and set up her cell phone and computers without Microsoft, Google, or Apple looking over her shoulder. She is concerned about tracking and privacy. I can give her help with her future Linux desktop, but I don't even own a cell phone so I can't advise on "Linux" cell phones (or any kind of cell phones). Anyone out there in Linux-land with experience they are willing to share using a cell phone with good privacy that doesn't track you? -- | Ian! D.

I found this estimated performance comparison site that shows that every other card they list is between 190% (GeForce 21) and 34,249% (GeForce RTX 3090) faster than my old 2009 FirePro 2450: https://www.techpowerup.com/gpu-specs/firepro-2450-multi-view.c1384 > VGA: VisionTek 5450 PCIE 512M ATX Dual DVI B2 They estimate the Radeon HD 5450 at 384% faster than my FirePro 2450. My glmark2 score of 173 multiplied by that 384% gives 664, not too far off your actual score of 511.

I think my FirePro glmark2 score of 173 is the big problem, and perhaps most any modern video card can do much better than that. Maybe I can even find one that is passive-cooled and doesn't need a noisy fan. I really do want the faster M2 and faster SATA and USB3, and more memory, so just a video card upgrade won't give me everything I want.

[linux] time to upgrade from 2008 technology, need OBS Studio
I'm running 2008 desktop technology and want to upgrade so that I can get more than 5 FPS out of OBS Studio when using Zoom. I have: - AMD Phenom(tm) II X4 965 Processor - M4A79T Deluxe AM3 ATX DDR3 790FX 4PCI-E16 2PCI SATA2 eSATA Motherboard - 16 GB memory - AMD/ATI RV620 GL FirePro 2450 512MB DDR3 PCIe x16 Quad DVI OpenGL 3.3 - Three Dell 1600x1200 LCD DVI monitors. - Various M2 NVMe, SSD, and hard drive storage. I figure I should multiply everything by about four, so 16 cores and 64 MB memory, so maybe AMD Ryzen 9 3950X or even 5950X (if available). (I suspect having faster single-CPU response will be better than having more and more cores.) But I don't do any "gaming". I don't need to shoot things at 4K resolution. (I'm not upgrading monitors; I'm happy with three 1600x1200.) All I want is a quiet video card that occasionally runs OBS Studio into Zoom under Linux faster than about 5-10 frames per second, and nobody is writing video card reviews with that in mind. Suggestions? I could just do what Linus Torvalds did: https://www.zdnet.com/article/look-whats-inside-linus-torvalds-latest-linux-development-pc/ https://www.zdnet.com/article/you-can-build-linus-torvalds-pc-heres-all-the-hardware-and-where-to-buy-it/ He used "Some random Sapphire RX580 graphics card."

Re: [linux] rsync snapshot backup
What format is your backup drive? If the backup drive is formatted to a file system that does not support links (like exFAT ) hard links will be copied as duplicate lfiles and soft links may not be copied at all. SSDs and hard drives are usually supplied with a Windows file format, such as exFAT or NTFS and would need to be reformatted to a linux file system (such as the default format for your own linux systems, begore they will work properly with rsync.

I didn't see this feature, though the ipset-blacklist.conf lets you download country block lists using separate URLs each with a country code. Something I didn't see: I've found it helpful to have a white-list of addresses that never get added to the block lists on my machines. The white-list includes all my own servers and my current ISP DHCP internet assignments. Since ipset-blacklist is only a 113-line bash script, adding a white-list feature using "iprange --except" wouldn't be hard. Has anyone already done this? I note that there is an ugly bit in the script where various local IP addresses are removed using "sed" with regexp patterns - this would look much nicer using "iprange --except" as part of a generalized white-list processing, if iprange were available. Things in the script suggest the programmer hasn't had a lot of experience writing scripts, e.g. using: $(wc -l "$IP_BLACKLIST_TMP" | cut -d' ' -f1) instead of simply: $(wc -l <"$IP_BLACKLIST_TMP") Also the script doesn't check the error codes of commands, has unnecessary use of "command" in "command grep" everywhere, and doesn't use "sed -n" or other things efficiently, among other things. But it's a good start. -- | Ian! D.

I'm curious about the above statement, since I use submission/POP3 to Algonquin College for my "all...@algonquincollege.com" email and the domain name I use is a generic Microsoft domain both ways. uOttawa can't block POP3/IMAP since they can't block the port on the Microsoft domain, but maybe they can disallow authentication once connected? (But then how does "Exchange" authenticate?) To send College email I (using postfix) connect to the "submission" port (597) at outlook.office365.com and log in using my Algonquin email address. I gather uOttawa won't let you log in? The "From:" field on any email I send has to match my Algonquin email address or else the message is rejected. Whatever name text I use on the From: line is replaced with the College standard "Ian Allen". To receive email (using fetchmail) I connect to the POP3 port at outlook.office365.com and log in using my Algonquin email address. I gather uOttawa won't let you log in? > Note that my fallback is to reset on NCF, with uottawa forwarding. Yes, when Algonquin used in-house email and blocked POP3/IMAP, I used to forward all Algonquin email to another machine that did allow POP3. Once Algonquin moved to Office 365, POP3 came with it, so I stopped forwarding. Have you tried POP3 to outlook.office365.com ? I used to send official College email from my usual mail host, but with the "From:" line set to my College email address and the "Reply-to:" line set to idal...@idallen.ca. That started going into spam folders this month, so I started using the College "submission" port instead. I use a "mutt" send-hook to rewrite my "From:" address whenever any recipients are at the College, and a postfix transport map to send any email destined to the College into the College submission port. -- | Ian!

The problem could be Linux mis-handling the RAID1 on those drives, which means the problem will only show up with two drives and is not the fault of either drive. -- | Ian! D.

LXDE is OK, but I like > the XFCE panel quite a lot. I start stock Ubuntu. When I log in, I kill off gnome-shell and nautilus-desktop, and start vtwm with bunches of urxvt (via urxvtd) running tmux with bunches of windows. Every urxvt has the access to the same list of 40 tmux windows. I have four vtwm virtual desktops stacked vertically with five urxvt horizontally on each, across two 1600x1200 monitors, with a third monitor for Firefox. I still have parts of my .vtwmrc and .Xresources that I used for twm back in the 1980s. > > (oh yeah, and no use at all for CAPS LOCK). > You can xmodmap CAPS LOCK into oblivion... Yes. -- | Ian! D.
