Emacs yellow areas tracked down

Posted By Greg Lehey

While writing yesterday's diary entries, ran into another case of a yellow-stained Emacs buffer. This time I grabbed the lossage: SPC O K , SPC h a c k SPC a r o u n d SPC i n SPC <switch-frame> C-x C-f C-g C-x C-s <help-echo> <M-drag-mouse-2> <M-drag-mouse-3> <switch-frame> <switch-frame> M-x v i e w - l o <tab> <return> Clearly this happened as the result of one or more of <help-echo> <M-drag-mouse-2> <M-drag-mouse-3>. But what do they mean? The drag-mouse events are clear, but <help-echo>?

Communicating by email

Posted By Greg Lehey

My problems with Red Energy yesterday haven't been the only ones where I have problems communicating by email. I've had two others in the last year, first with a company that might be called Resilium, and more recently with Elysian Energy. In all cases, communicating was like pulling teeth. Why? Part of it is clearly the practice of replying to a message in a separate place from the message itself. This is the way it has always been with conventional mail. But when I wrote lots of conventional mail, over 50 years ago, I might have been replying to a multi-page letter, in which case I would have it on the desk next to me.

GPS comparisons, finally

Posted By Greg Lehey

So finally I have made maps from the track logs that I created while travelling to Napoleons on Thursday using GPS Visualizer. They're certainly interesting. First, the whole journey, as logged with taskumatti (my old Nokia 3 phone), flachmann (the new Nokia 5.1 Plus phone) and my old dedicated GPS navigator: I went to Napoleons and returned via the same path, so there should be no loops in the track logs.

GPS comparisons

Posted By Greg Lehey

I've been dragging my heels on my GPS receiver comparisons. There's a good reason: it's a pain to access these things. Now that I have file-system like semantics to access the telephones, that's not so bad, but I had forgotten how to access the dedicated unit. The first step is clear: connect the unit to the computer with a USB cable: Mar 27 12:14:13 eureka kernel: ugen0.11: <MStar Semiconductor, Inc.> at usbus0 Mar 27 12:14:13 eureka kernel: umass4: <MStar Semiconductor, Inc.

Weather station pain

Posted By Greg Lehey

My weather station is still having difficulties communicating with the outside unit. That's nothing new: I've had these issues for over 10 years, but for some reason they're getting worse. It's clearly related to the position of the internal unit, and I've been moving it around the office to try to get better communication. The obvious thing to do is to put it in the lounge room. Like that it almost has a line of sight to the external unit, and the internal measurements are more meaningful. That requires connecting the unit to teevee. But for that I had to work my way through these bizarre MySQL permissions, which I still don't understand.

Working from home

Posted By Greg Lehey

Due to the COVID-19 pandemic, lots of people are working from home for the first time. And of course lots of other people are trying to sell the solutions to their perceived problems. How-To Geek has many suggestions for The Best Work From Home Apps for iPhone and Android. I only have one: avoid them all. The devices have been optimized for people moving around, to the detriment of use in a single place. One exception comes to mind, though: The 6 Best Free Video Conferencing Apps. I don't have a camera on eureka, and I don't know of anything that would work with FreeBSD.

Another FTP server

Posted By Greg Lehey

Daniel O'Connor pointed me at an alternative FTP server yesterday. FTP? Everything! It's a Servers Ultimate, reminding me that ?ultimate? means ?last?, and that the German translation ?das Letzte? an extremely negative evaluation is. And indeed, it had servers. 5 different FTP servers. What are they all? Of course it's too polite to assume I wouldn't know. Some worked for me, some didn't. But while looking around on their web site, found: This app will work for 7 days after which you will need to buy the paid version. BAD Servers Ultimate.

Nokia 5.1 Plus: yes or no?

Posted By Greg Lehey

So: I've had the Nokia 5.1 Plus for 12 days now. Another 48 days before I need to give it back if I don't like it. What advantages does it have? Why was I even interested in a new phone? The issues I have with the older Nokia 3 are many and varied. The ones that continually irritate me are: Messages that appear on the screen when the display is turned off, then stay for about 4 seconds before disappearing forever.

More mobile phone fun

Posted By Greg Lehey

So now I have file access to flachmann, my new Nokia 5.1 Plus, via a file system interface. But it's FTP, not exactly state of the art. How about an HTTP access method? I can access the file system on taskumatti (my old Nokia 3) via HTTP, but not via FTP, using the same app, WiFi File Transfer. OK, off looking. Yes, there's a port fusefs-httpfs, which not only installs, but also produces a message: ===>   NOTICE: The fusefs-httpfs port currently does not have a maintainer. As a result, it is more likely to have unresolved issues, not be up-to-date, or even be removed in the future.

Battery calibration without end

Posted By Greg Lehey

When I got into my office this morning, yesterday's PV battery calibration was still going on: Three complete cycles, and it was continuing into the fourth. When it got to the fully charged state of the fourth, I power cycled the inverter, but it's becoming clear that that won't stop it. Time for a stiffer letter to the suppliers, asking for: As I asked last August, please get me a statement from the manufacturer (not from you) by 10 April answering the questions: How often should this recalibration take place?

File access in the age of Android

Posted By Greg Lehey

I've had my new Nokia 5.1 Plus for 10 days now, and so far the experience has been mixed. I've found a number of apps that seem better than what I have used before, but I'm still running into this frustrating now-you-see-me-now-you-don't message stuff. But that might be a Nokia taunt. One difference is that WiFi File Transfer only provides FTP access, while on the older Nokia 3 it offers HTTP. I've been thinking for some time about my most basic question, last asked when I got the phone: But surely, surely, there is software available for that most basic of network functionality, copying data from one system to another?

File access in the age of Google

Posted By Greg Lehey

Peter Jeremy has given me access to a large collection of files on Google Drive. There must be several terabytes of them. OK, follow the ?invitation? and get a list of names. besplex, epsplex and so on. What are they? My understanding is that they're disk images of some kind, but Google Drive tells me that they're ?Google Drive folders?. What can I do with them? I have no idea. I'd expect to be able to select them show the component files, but I failed in that attempt. Once again, the Google interface is so non-intuitive that I can't make head or tail of them.

Shell scripting for personal productivity

Posted By Diomidis D. Spinellis

In an edX course on Unix tools I am running these weeks, I got asked for ideas on how shell scripts can be useful . This is a very interesting question, because the course focuses mainly on performing one-off tasks in the areas of software development, data engineering, and system administration, rather than automation through shell scripts. Here's how I'm using shell scripting to enhance my personal productivity. I'll post further installments regarding software development and system administration.

More GPS navigation fun

My GPS navigator works even worse than before. It reached the end of time a year or so ago, and last month I left it out in the sun (wouldn't you think a navigator could deal with that?) : Since then it doesn't work too well, and I'v ebeen thinking of a replacement for a while. Today's trip to Ballarat was worth another attempt. Off to the toyshop to see what was on offer. I discovered an app already installed: ?Australia Topo Maps?.

OED access in times of COVID-19

Posted By Greg Lehey

I access the Oxford English Dictionary several times a week via the State Library of Victoria. It's convenient and free. Somewhere I have a DVD of the Second Edition, but it's easier via the web. But today I was unable to access the service. ?You could not be signed in. This account has no valid subscription for this site?. Damn. What has gone wrong there? The only credentials I need are the ones I need to access SLV, and they were OK. OK, report a bug? No provision for that on the SLV web site, just ?ask a question?. OK, ?ask a question?, specifying a reason.

Somehow the last week has been particularly stressful, and it had its overhang into today: I didn't get yesterday's diary entry committed until 16:54. But that's about all I had to do today. Yes, Yvonne managed to find an interesting bug in avidemux: when saving a clip, if you forget and use the standard Emacs c-x c-s, avidemux does save a clip. But it's not the one you selected: it's the one to the left of the A mark (in other words, the part cut off at the beginning).

Facet: Push vs Pull

Posted By Tim Bray

If you want to process events, you can fetch them from the infrastructure or you can have the infrastructure hand them to you. Neither idea is crazy. [This is part of the Event Facets series.] When you make a request to fetch data, that?s called ?pull?. Which is an off-by-one error; the ?u? should be an ?o? as in ?poll?, because that?s how most network stuff works. I?ve heard old farts of my own vintage claim that on the network, polling is really all there is if you dig in deep enough. But we do use the term ?push?, in which???maybe it?s just an illusion???the infrastructure reaches out and hands the event to you.

What explains the counter-intuitive numbering of chip pins?

Posted By Diomidis D. Spinellis

One of the first things one learns in electronics is how chip pins are numbered. In the common dual in-line package (DIP) pin numbering starts from the left side of a notch appearing on the top of the package and continues counterclockwise until it reaches the other side of the notch. Why are pins counter-intuitively numbered in a rotating fashion rather than by columns as one would expect for a rectangular package? And why is the numbering not following the direction of a clock's numbers? I think that both decisions can be traced back to history.

Emacs strangeness

Posted By Greg Lehey

Seen in my calendar this morning: Mar 19  Greg installs BSD/386 0.3.1, 1992 28 years! But that's nothing compared to an editor that I installed some time in 1980, MINCE, a clone of Emacs for the Z-80 microprocessor. And I've been using some form of Emacs ever since (GNU Emacs since 1989). But lately I've been having surprises. I sometimes get areas of the screen marked with a yellow background. Why? What are they? I've done some searching, and most answers on the web seem to reduce to RTFM.

Another NBN outage notification

Posted By Greg Lehey

Recently I had over two weeks with no looming National Broadband Network outages, but last week another came??only? 15 minutes, and in the middle of the night. I can live with that. And then today another one came: NBNCo has let us know that they are planning network maintenance in your area, and that your service at 29 STONES RD, DEREEL VIC will be affected. The details are:   - Start date and time: Fri 20th March 2020 00:00 AEDT   - End date and time: Fri 20th March 2020 06:00 AEDT   - Window: 6.0 hours You may experience the following interruptions during the maintenance   - 90 min Not quite as acceptable, but in the middle of the night, so again, I can live with it.

Android: file access and ringtones

For some reason, my new Nokia 5.1 Plus is only partially compatible with WiFi File Transfer: it doesn't support HTTP connections. On the old Nokia 3 I could connect with a web browser like this: But on the new one (called flachmann now that the old tablet of that name is no longer usable), I need to use FTP: Is that a problem?

Yet another video editor

Posted By Greg Lehey

Finally I have avidemux working, sort of. But it has some irritating habits, and it's clear that it's relatively limited. What else is there? I had already tried kdenlive, running into problems with both performance and interface. Clearly interface is something that I need to get used to, but performance is an issue that might remain. So today Callum Gibson suggested openshot, something that I had been thinking of anyway. To emphasize the suggestion, he pointed to this page, which interestingly enough listed the four best packages (in order) as openshot, kdenlive, shotcut and avidemux. So another reason to try it.

Groggy's ports mistakes

Posted By Greg Lehey

I made a mistake on IRC this morning: * groggyhimself grumbles about ports. Ah, but that's my fault. I'm not just using ports, I'm mixing them with packages. Naughty boy! Is that wrong? I claim not, but others point to configuration differences between my system and the system on which the packages were built. Yes, the dependencies could be different. But that's exactly the point of the dependency database. I'm pretty sure that I'm doing it by the book, with some explicit exceptions, like extracting the package directly without passing "go" and registering with the database.

Using avidemux

Posted By Greg Lehey

So now, after only a week, I have a slightly castrated version of avidemux running on lagoon. Tried to show Yvonne how to use it, but failed. Although I had used it before, and though it's relatively sane, I forgot what the symbols mean. On a second attempt I was more successful. But then she tried by herself, trimmed video clips, save them and... they weren't there! After some investigation, discovered that avidemux is just as bad as all this GUI software that has no concept of directory trees. Or maybe almost as bad. You can specify at least one file on the command line, which produces many and varied illegible texts: And the first time round it happily provided the correct directory for saving the output file (/Photos/yvonne/20200317, the same one ...

Installing PyTorch on a Raspberry Pi-3B+ redux

Posted By Diomidis D. Spinellis

This is an update to articles for installing the PyTorch machine learning library on a Raspberry Pi that have been published by Amrit Das in 2018 and Saparna Nair in 2019 . It builds on them by updating the required settings and introducing a fix and a few tweaks to make the process run considerably faster. Although there are Python wheels floating around that offer PyTorch as a Raspberry Pi Python package, downloading them from unverified sources is a security risk. Here's how to install PyTorch from source.

avidemux debugging

So why did my avidemux build fail yesterday? I really need to find out. I had established that it claimed not to be able to find /usr/local/include/X11/X.h, but locate told me that it was there. locate gives a historical view. Was the file really there? === root@lagoon (/dev/pts/0) /usr/ports/multimedia/avidemux-qt5 293 -> locate X11/X.h ... /usr/local/include/X11/X.h === root@lagoon (/dev/pts/0) /usr/ports/multimedia/avidemux-qt5 294 -> l /usr/local/include/X11/X.h ls: /usr/local/include/X11/X.h: No such file or directory Gone!

New mobile phone

Posted By Greg Lehey

So now I have a new mobile phone, a Nokia 5.1 Plus. Why? I hate mobile phones. But maybe the issue was that my Nokia 3 was just too gutless?only about 100 times the processing power of the Intel 486 that I mentioned in Porting UNIX Software above. That would suggest that it could build the complete X system in 15 seconds. The advantage of the 5.1 Plus is that it's sold by ALDI, so I have two months to play with it, and if I don't like it, I can just return it. Fortunately it doesn't look like this image from Wikipedia, the stuff of my nightmares (keyboards with missing keys): OK, set up.

The next one is on its way:   - Start date and time: Fri 20th March 2020 00:00 AEDT   - End date and time: Fri 20th March 2020 06:00 AEDT   - Window: 6.0 hours You may experience the following interruptions during the maintenance   - 15 min Of course, a 15 minute outage (maybe!) in the middle of the night is almost acceptable.

Video editing: avidemux success!

Posted By Greg Lehey

Spent most of today writing up my diary entries for yesterday. It paid off, though: while reading what I had collected, I noticed that there were five ports with names starting in avidemux: avidemux, avidemux-cli, avidemux-plugins, avidemux-qt4 and avidemux-qt5. I had already established that I needed avidemux and avidemux-qt5, and had installed avidemux-cli to admire the screen vomit. That leaves avidemux-plugins and avidemux-qt4. Clearly avidemux-qt4 is an older version. And avidemux-plugins? No description, of course, and at first I had thought of it as extras, but what if it's part of the base port? After all, what use is the avidemux port with no executables?

Anandtech on AWS Graviton2

Posted By James Hamilton

Yesterday, Anandtech  published what is, by far, the most detailed write-up on the AWS Graviton2 processor. In this article the author, Andrei Frumusanu, compared the Graviton2 with the AMD EPYC 7571 and the Intel Platinum 8259CL. Worth reading.

In general, it seems that kdenlive is the most popular editor. It refuses to work over a network, but maybe it would be OK locally. Installed on teevee and tried again. It runs! And produces about 200 lines of error and warning messages on the xterm, for once without trying to change the colour. Presumably this is typical of developers thinking that they can flush their debug messages down the xterm, and is of no further interest. But then it brings a typical confusing error message: Huh?

Rediscovering avidemux

Posted By Greg Lehey

So, FINALLY, I had avidemux-qt5 installed, at round 14:00. Let's run it: The screen seems to be 1920 x 1080 px [destroy] 03:49:21-533  Destroying preview  [renderDisplayResize] 03:49:21-533  Render to 0x0 zoom=1.0000, old one =0 x 0, zoom=1.0000, renderer=0x0  [UI_resize] 03:49:21-534  Resizing the main window to 152x230 px [RDR] Resizing to 0 x 0 [initGUI] 03:49:21-535  OpenGL enabled at built time, checking if we should run it.. What are all those empty lines? Ah, they're not empty, just tastefully set to displaying white foreground on your choice of background. You can mark them, for example, which also makes them visible.

More video editor pain

Posted By Greg Lehey

So first let's try to get the video software that I have to run. It's excruciating for multiple reasons. First another look at avidemux. Why is there no executable? Ah, that's for me to know and you to guess. There are a total of five ports: avidemux, avidemux-cli, avidemux-plugins, avidemux-qt4 and avidemux-qt5. What do the pkg-descrs say? A video editor that allows editing of AVI, OGM, and MPEG videos. The MPEG support provides the ability to convert to DVD compliat PS streams. It contains various filters for deinterlacing, cropping, resizing, etc. Allows for cutting without re-encoding. Has the ability to re-encode and re-sample.

Facet: Broker vs Serverless

Posted By Tim Bray

Your event infrastructure might be a service in the cloud or might be an actual computer (or cluster) you connect to. Both choices are perfectly sensible. The trade-offs? It?s complicated. [This is part of the Event Facets series.] At AWS where I work, our mainstream home-grown services (Kinesis, SQS, SNS) are all serverless. I mean, there are servers, lots of ?em, but you can?t see ?em, there?s just an endpoint that you connect to, usually with HTTP, to produce and consume events. Which should be unsurprising, AWS is built on the proposition that everything should be a service.

More video processing pain

Posted By Greg Lehey

More investigation of the files that I had ripped yesterday. The good news: the audio worked after all; the error messages were just confusion on the part of the player. The bad news: some of the episodes had not been decrypted. As planned, conected up my ancient Digitrex GKX-9000 DVD recorder to the TV monitor today and put in one of the Heartbeat DVDs. It worked and behaved correctly, including providing me with the titles, which none of the software had extracted. OK, how about copying the entire DVD to disk? It proves that vobcopy has a corresponding option: vobcopy -l -m The -l option shouldn't be necessary, but otherwise vobcopy thinks that files can't be larger than 2 GB.

Facet: Point-to-Point vs Pub/Sub

Posted By Tim Bray

When there?s an event in the cloud, how many different receivers can receive it? There are two plausible answers: Just one, or anyone. [This is part of the Event Facets series.] Point-to-point The idea is that any given message can only be read by one receiver. You might imagine that, as the old photo above suggests, the sender supplies an address, choosing the receiver. But that?s actually a pretty rare scenario. What?s much more common is the way that SQS works. In SQS, when you send a message, you have to pick which queue you?re sending it on.

This can take a _long_ time

Posted By Greg Lehey

Julie Donaghy had had some DVDs of Heartbeat for sale yesterday, but we didn't take them: we already have the episodes. But then it occurred to me that the quality of the copies I have is pretty terrible, so for $5 for 17 DVDs (5 seasons) it seemed to make sense. So today Yvonne went off to pick them up. 17 DVDs? She came back with 54! Julie had lent her the complete DVDs for Lost, of which we had never heard, but which Julie says is excellent?IMDB agrees. OK, the usual problem: we don't have a DVD player, so I needed to read them in to disk.

Facet: Deduping

Posted By Tim Bray

When you fire an event into the cloud, can you be sure it?ll only come out again once? It turns out that sometimes they come out more often than they go in. This may or may not be a problem in your application. If it is, there are techniques to help work around it. ?At-least once? This is a phrase you?ll hear a lot when you hang around with eventing/messaging people, (and cloud people generally). Builders work so hard at making sure everything gets delivered that they can end up doing it more than once. How can that happen?

Eventing Facets

Posted By Tim Bray

What happened was, at re:Invent 2019 I gave a talk entitled Moving to Event-Driven Architecture, discussing a list of characteristics that distinguish eventing and messaging services. It was a lot of work pulling the material together and I?ve learned a couple of things since then; thus, welcome to the Eventing Facets blog series, of which this is the hub. It?s going to take a while to fill this out. Eventing or messaging? They?re just labels. If it?s publish-and-subscribe people usually say ?event?; if there?s a designated receiver, ?message?. But there?s a lot of messy ground in between; and in my experience, the software does more or less the same stuff whichever label?s on the cover.

Facet: FIFO

Posted By Tim Bray

When you inject events into the cloud, do you care whether they come out in the same order they went in? If you do, you?ll be asking for ?FIFO? (rhymes with ?Fly, foe!?) (stands for ?First In First Out?) . Some software has it, some doesn?t. [This is part of the Event Facets series.] If you think about it carefully, FIFO is only meaningful when you have a single-threaded sender and a single-threaded receiver; with more than one, who gets to say which message was sent (or received) first? Real-world FIFO semantics.Credit: ?Caravan in the desert.

What can software developers learn from the Soviet Moon Landing Program?

Posted By Diomidis D. Spinellis

In the twentieth century space race between the Soviet Union and the United States the former started way ahead. In 1957 it launched the first artificial satellite, Sputnik 1, and in 1961 it had Yuri Gagarin orbiting the Earth as the first human to space. Yet, when it came to landing a person on the Moon it flopped spectacularly, abandoning its N1 rocket and Soyuz spacecraft program after a series of fiery failures. It turns out that the problems of Soviet program's N1 rocket ? one cased one of the largest artificial non-nuclear explosions in human history ?

PIXIO fail

Posted By Greg Lehey

Yvonne wanted to take another sequence of video clips today using the PIXIO ?Robot Cameraman?. Set it up in place, turned on the beacons... nothing. No power. Further examination showed that it was only beacon 1, which appeared to be completely discharged. Aborted the effort, with considerable growling on Yvonne's part, and put the things on charge. Yes, everything was charged except for beacon 1, which charged normally. What's the issue? Apart from the documented bug with the controller itself (after charging you must power it on, then off again, to avoid immediate self-discharge), I've seen the beacons spontaneously turn on when removed from the charger.

Daily teevee update

Posted By Greg Lehey

The updated teevee is now working well enough for me to be able to use it, but it's still not fixed. What's the story with the keyboard mapping? And why can't I start X from the startup script? For the X problem I tried a solution suggested by this page. Create /etc/X11/Xwrapper.config with this content: allowed_users = anybody Then to investigate the keymap. Clearly I needed the old system to compare with, so rebooted there and saved the keymap with xmodmap -pk. Boot back to the new system.

teevee progress

Posted By Greg Lehey

The daily teevee pain today. First, check out a pristine copy of the source tree and build a new world, again, this time with a kernel that divulges when it was built. I've run into this before, but I thought people were going to fix the bugfeature. It took me a while to find this completely non-intuitive setting, only six months ago: create a file with an equally unlike name /etc/src.conf and add: # Don't drop build date, dammit! # What a silly name for the knob. WITHOUT_REPRODUCIBLE_BUILD=dammit Was that the correct syntax?

Nokia 3 ring tones die

Posted By Greg Lehey

Six weeks ago, after upgrading the operating system on my Nokia 3 mobile phone, I discovered that it no longer produced a ring tone for an incoming call. That's basic telephone functionality! It proved only to have disabled my custom tones, so I growled and installed one of their particularly emetic standard tones. But today Yvonne called me from town. Only vibrate. Fortunately I had it in my shirt pocket, so I received it. But now no tone sounded, not even when I tried to select them, something that had previously worked. A bit of searching on the web proved this is not specific to Android 9 (or whatever the silly name is).

teevee build pause

Posted By Greg Lehey

So how do I handle my issues with upgrading teevee? On the face of it, the upgrade process is broken. But why does nobody else complain? Obvious reasons could be that they maybe think it's modern, or that they don't want to make fools of themselves complaining in public: I belong (currently, at least) to the latter group. Other reasons could be: Incompatible boot blocks causing the lua errors and possibly the keyboard bounce.

Shotcut: book with seven seals

Posted By Greg Lehey

Yvonne spent some time this afternoon trying to use shotcut to trim a video clip, with spectacular lack of success. Apart from the fact that the use of the interface is completely at variance with anything I have ever seen, she wasn't even able to save the result. When she tried, all she got was a small XML file. OK, see what I can do. FOOL! You don't save files, you export them. OK, tried that, after finding out how to trim files (simple: take the start and end markers and move them to the point you want?if the markers are displayed, which isn't all the time).

Daily teevee pain

Posted By Greg Lehey

At least one of yesterday's problems with the teevee upgrade, the lua errors, could have been that the source tree was updated between building world and installing world, so built another world today. To boot the new system cleanly, copied the old /boot/lua directory to the new system, and it booted cleanly. But I still had these repeated characters from the keyboard, to the point that I couldn't log in as rooott at all. I had to go to eureka and log in via the net. While I was there, ran make installworld. This time it ran cleanly. Reboot. Those bloody lua messages again!

eBay notifications

While in the lounge room, logged in to eBay, apparently for the first time in this instance of teevee. That required me to find the email address and the (unflattering) password. And then I got this message: What nonsense is that?

teevee upgrade

OK, time for action on teevee. I still have two root partitions, so given the issues I have, maybe the idea of alternating them isn't such a bad idea after all. Copied one to the other, remembered to update /boot/loader.conf on the first partition to point to the second: Then reboot. Oh. Forgot to update /etc/fstab on the second partition, so I ended up mounting the first partition after all. Reboot, run pkg upgrade on the second partition. Number of packages to be installed: 62 Number of packages to be upgraded: 433 Number of packages to be reinstalled: 70 How long since the last upgrade?
