IPv4 subnet/CIDR table from OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation …”

Posted by jpluimers on 2024/11/27

I wrote about programs and scripts doing IPv4 subnet calculation, but sometimes it is easier to have a table at hand, so here is the one I found at [Wayback/Archive] OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation #networks #networkbasics #subnetting #infosec #networks4hackers #cyberwarrior #cyberwarrior #networkbasics #networkbasics subnet”

Jeffrey | JKCTech on X: “Dit is echt 1 van de aller mooiste edge cases voor een licht sensor die ik ooit heb gezien… https://t.co/wkm8ztbHI9” / X

Posted by jpluimers on 2024/11/26

[Wayback/Archive] Jeffrey | JKCTech on X: “Dit is echt 1 van de aller mooiste edge cases voor een licht sensor die ik ooit heb gezien… “

It references a movie by Dutch humor site (often on the wrong side of humor) Dumpert:

[Wayback/Archive] DUMPERT – Ambulance naast lichtsensor flat =

which they also put on YouTube: [Wayback/Archive] Ambulance + lichtsensor = flatrave! #shorts – YouTube.

It teaches to adjust the light sensors so they don’t kick in turning the light off too soon after it gets dark.

For the USA, the TRS-80 PC-1 was the “The Trash Computer That Became Your Phone”; the rest of the world could enjoy the hardware identical Sharp PC-1210/1211/1212 years earlier

Posted by jpluimers on 2024/11/25

Earlier this year, I bumped into [Wayback/Archive] The Trash Computer That Became Your Phone – YouTube which discusses the Tandy  TRS-80 Pocket Computer PC-1, . The video includes a lot of history about Tandy Corporation, Charles Tandy and Radio Shack including quite a few bits I didn’t know yet.

It was part of the Tandy Pocket Computer, and succeeded by the Z80 powered TRS-80 Pocket Computer PC-2 (which was actually a rebadged Sharp PC-1500).

The TRS-80 Pocket Computer PC-1 itself was also a rebadged Pocket Computer, this time a Sharp PC-1211 powered by a duo of 4-bit CPUs so totally incompatible with the PC-2. Actually none of the Tandy Pocket Computer line were compatible with each other (nor with the desktop TRS-80 which itself was incompatible TRS-80 Color Computer). With the PC-4 and on Tandy even switched to Casio as manufacturer, then back to Sharp for the final PC-8.

Anyway: this video was a trip down memory lane and reliving my 2012 blog post The calculators that got me into programming (via: calculators : Algorithms for the masses – julian m bucknall), and I was glad that by now there are more videos covering the calculator I started with, for instance via [Wayback/Archive] sharp pc-1211 – YouTube:

Hopefully this has made it into a set by now: LEGO IDEAS – This Is Fine

Posted by jpluimers on 2024/11/25

Often it can take a long time for first getting 100 votes, then via milestones 1000, 5000, 10000 and a long review phase to become an actual set.

Hopefully by now [Wayback/Archive] LEGO IDEAS – This Is Fine has become a set or at least someone used Bricklink Studio designer and uploaded the model or instructions.

Edit 20241125:

Nope, LEGO decided they didn’t want to make money of this set as communicated in their [Wayback/Archive] LEGO IDEAS – This Is Fine: Official LEGO Comments

Unfortunately, the LEGO Review Board has decided that we will not produce this project as a set.

But others did:

Looking at the price difference between these two, LEGO could have made quite a bit of money.

Not just on a new tab: MacOS chrome crashes when command + shift + i is pressed on a new tab [333424895] – Chromium

Posted by jpluimers on 2024/11/23

April 2024 this bug was reported: [Wayback/Archive] chrome crashes when command + shift + i is pressed on a new tab [333424895] – Chromium

That one was fixed, but it looks shortcuts like Command (⌘) + Shift + I still break Chrome when used on a tab pointing to a web-site.

Hopefully the original fix at [Wayback/Archive] Fix crash in sharing menu (5449679) · Gerrit Code Review will help people fixing the standing issue as well.

Related (I plan to file a bug report when the number of my open tabs is closer to zero from the current 200+):

ValueError: invalid literal for int() with base 10: ” by tzwickl · Pull Request #768 · sivel/speedtest-cli

Posted by jpluimers on 2024/11/22

Somehow this post missed the schedule and for a long time I forgot to properly checked for “missed schedule” posts.

Back in 2021, suddenly systems with speedtest-cli threw a [Wayback/Archive] ValueError: invalid literal for int() with base 10: ” by tzwickl · Pull Request #768 · sivel/speedtest-cli after accessing the speedtest.net servers.

Around 7-8 April, 2021 the speedtest.net/speedtest-config.php XML configuration suddenly had changed the value for the XPath expression /settings/server-config/@ignoreids from being a list of integers into empty, see the archived files below.

The Twelve-Factor App

Posted by jpluimers on 2024/11/21

Still relevant: [Wayback/Archive] The Twelve-Factor App and [Wayback/Archive] 12 Fractured Apps — Medium

Once Docker hit the scene the benefits of the 12 Factor App (12FA) really started to shine. For example, 12FA recommends that logging should be done to stdout and be treated as an event stream. Ever run the docker logs command? That’s 12FA in action!
