PhotonicInduction is the extreme version of this, he's an electrical engineer / "mad scientist" who builds ridiculous things such as enormous capacitor banks for blowing things up, power supplies that deliver many kV for feeding to various household appliances, record players that spin at 10,000 RPM and that kind of thing. He also demos old tech you wouldn't see in other places like mercury arc rectifiers. Definitely "don't try this at home" but it's usually really interesting to watch.

Oh yeah, Royal Mail are annoying for that, especially since the sorting office around here is in the middle of nowhere. Every other courier will try a neighbour though.

My wife and I used to live in a street where we were usually the only people at home during the day. All the delivery companies quickly realised we would take in anyone's parcels, so our living room was often like a mini sorting office!
Ok, so because other companies do that it should be acceptable? I don't understand your patronising tone. How is that helpful?
Comments like this make me wonder if people really expect engineers to be fired because of an outage? I do not work at Google, but none of my workplaces would fire engineers because of a failure. Mistakes happen. As long as they are not repeated, everything is good.

If your company fires people in situations like this, run away and never look back.
Their internal platform is likely analogous in terms of accumulating complexity (and a bit of cruft) over time though
I am the co-founder of one of the honorable mentions in the list of viable software (Supernotes), happy to answer any questions people might have!
A big part was that pascal had a decent module system, while C only has includes. The same header files can be included from multiple places and have to be processed multiple times. IIRC the Plan9 C compiler had some restrictions (or maybe just conventions) to prevent this.

Also, Borland Pascal / Delphi compilers weren't terrible at optimizing. And they often produced smaller executables.
Then it might, indeed, be unrelated. Thanks for clarification!
Looks good, but always when I see stuff like this I just think functionally it's just for show. I'm function over form every time.

What's it going to look it in 10/20 years. I feel the "inspired by nature" bit is non-sense. There's better ways of "surrounding yourself by nature" that is more functional and not as gimmicky.
Which is why I've always stuck to `perl -pi -e`.

It may not be as powerful but it's just one thing to learn. Also it understands regexs like '\d', etc which are kinda universal but for some reason don't work with many of these utils.
The Secret Life of Walter Mitty explores this. I recommend everyone to watch it.
Apple stopped supporting 32-bit code in Catalina (10.15, released October 2019.)

Calculating ROI on any BI system intended for internal decision making is always tricky. A self-service solution does give you some options though. You can estimate the total hours saved from easy and reliable access to data via the self-service solution versus the current channels (manual extracts, manipulation in Excel, etc.). Start by assessing how many users the self-service solution would have (these could include analysts, controllers, managers, etc. throughout the organization) and ask them to estimate how much time they currently spend retrieving the same data that the self-service solution would provide. Multiply the estimated monthly hours saved by the average hourly salary cost and you have a quantified estimate. Other benefits of BI systems are less quantifiable. A big one is that you will provide a single source of truth which avoid teams arguing whether a specific KPI value is this or that because they each calculated it slightly differently.

I've recently had one or two packages left in my recycling bin for paper/cardboard with a note from the driver saying they put it there. That was kind of a shock, because that's simply not done here in the Netherlands unless you have a personal understanding with the delivery driver.

It was also really uncomfortable because I definitely don't want delivery drivers walking anywhere around my house except for the path from garden gate to front door.
> But now you have someone in your team who will never, ever make that same mistake again and that should be your new go-to guy for all DNS related changes.

I'm not entirely sure that's always true. For example, i've seen people introduce N+1 issues into a codebase, spend evenings fixing them and refactoring code to fix production issues... just to later introduce those very same types of issues.

Sure, you can learn from mistakes, have post-mortems and so on (provided that your org even does those and that anyone listens and cares about the conclusions from those), but to me it feels like the most foolproof way is to ensure that no-one can make these mistakes again, be it with a checklist (which tend to be ignored, honestly), or better yet, an automated CI step or a new test suite.

In my eyes, it's basically the same as with unit tests - everyone agrees that you need them, but people rarely write enough of them. So if you introduce something to prevent them from not doing what they should, e.g. a quality gate within a CI step which will disallow a merge once the coverage falls below a set margin, suddenly things are a lot better in the long run.
No mention of ';' to have multiple command on one line.

The main reason for this is not just a cultural difference, but a legal difference. Only the USPS can legally deliver to mailboxes. Otherwise, other services would definitely use them. There are, in some cases, other delivery services that ask their customer to have separate delivery boxes installed for their packages.

For example: https://img1.etsystatic.com/055/0/7471543/il_fullxfull.74786...
I don't want my post delivered to my neighbour. I much prefer the system we have which sends me a text saying that the package has arrived at the nearest pickup point which is a supermarket within five minutes drive or a locker that is less than ten minutes walk away.

Also, my neighbours are no more likely to be at home than I am.

Edit: forgot to specify that this is in Norway.
They have to make money somehow, otherwise they go out of business and everyone loses.

If you are involved in a project that absolutely requires compliance with an ISO standard, you are very likely making money from that project as well, and you should have factored the cost of the standard into that.

On the bright side, most university libraries, and I imagine many public libraries, will have access to these standards for members.

People do absolutely NOT get fired over incidents. Making mistakes is human. An incident will prompt a review of the systems and safeguards in place to prevent such an incident, much like an airline incident investigation -

basically "somebody fat-fingered it" is never the answer, postmortems are always blameless

EDIT: now that I think of it, the opposite thing happens after a major incident - a systemic failure should be identified, people are being hired to fix it :)

I liked the premise of this article, but I didn't see much use for anything after it started talking about how to achieve it.

...Except the 'personal stack overflow ' idea. Because so many of the answers to my questions are there, or in rando blog posts, having a personal SO full of actual SO answers (that I found useful) would actually be pretty good. Then a personal Google to search it and I'd be most of the way there.
I'm actually curious about the history of the backslash character. It does seem that it's something that isn't needed, and is not part of normal English writing, so I wonder how it made it into ASCII. Was it already in regular use in teletype? Was it used in technical writing in the 70's? Was it useful for formatting telegrams or something?
I have yet to find a music player that fits my odd requirements. My tracks have additional user metadata in TXXX frames. Over the years I've added multi-value tags like "instruments", "keywords", "moods". The only music player that works for me is MusicBee, which lets me define my own tags, and can index and search these tags. So a typical search might be "energetic uplifting synthesizer". I can sort by rating, last played etc, and add tracks to the queue before modifying my search, perhaps based on tracks the previous search found. I rarely choose music based on artist/album/genre. Unfortunately that means that pretty much no other music player works for me, and that sucks because I only use Linux, and MusicBee is a Window-only app that doesn't work perfectly on Wine (some UI issues have me stuck on an old version). Anyway, it's always worth throwing out there whenever someone brings up a music player. I'll check this one out.

Also radiations, temperature variations, and space dinosaurs. But it's still fun to think about it.
Delivery dates shift. Amazon's are doubly fluid. You might have to stay at home for a whole week have a reasonable chance of being there when the package deigns to be delivered.
Most examples that use '#!/bin/bash' should be rewritten to use '#!/usr/bin/sed -f'.

Example "multiple replacements":

Save it as replace.sed;
chmod u+rx replace.sed; ./replace.sed myfile.txt
I wholeheartedly agree. But the moment we get to government, we ran into politics. And this isn't local government either but International level. And navigating government and politics is about hundreds times harder than getting companies to together and donate. Which in itself is no small feat.

On one hand I wish a single government, EU or US will fund the whole thing and be proud and say it is such a pathetic small amount of money for so much good we are doing it anyway. Gets point for some international recognition or political power or whatever politicians wants.

On the other hand you know this wont happen.
I don't think so; the angling of the mirrors is done with small steps, which the mirrors smooth out.

Yeah it's LLVMpipe, it's basically doing everything in software and Plasma uses quite a bit OpenGL for animations and compositing. A lighter WM like Fluxbox could maybe be easier on the CPU. In any case, looking back at Nouveau, writing decent drivers for a GPU nobody has specs of is definitely challenging. Only time can tell.

MetaQuotes celebrates 17 years of its MQL5.com algorithmic trading community
The largest community of developers and algorithmic traders MQL5.com celebrates its 17th birthday on November 11, 2021. The community history began from the launch of the MQL4.com website which was named after MetaQuotes Language 4, the integrated programming language for developing indicators and trading strategies for the MetaTrader 4 trading platform. In 2010, following the release of the new MetaTrader 5 platform and MetaQuotes Language 5, the community turned into MQL5.community.

If you use `<script setup>` in Vue, yeah it's some compiler magic similar to Svelte, but otherwise that's not really the case, for example Vue tracks depdendencies using ES6 Proxy, which is just a language feature.

Well, there are various whitepapers that reformulate this exact truth you've highlighted: issues tend to happen more when changes are made.

Regarding the technical details doc, Google will never state that outright in individual postmortems. And they will definitely not draw this to the logical conclusion regarding the spiky yearly activity.

Marijuana doesn’t “make you dumb”. There are lots of specific effects and I do not generally advocate that anyone start taking marijuana, but I will say I am a 37 year old robotics engineer and I vape marijuana (doses on the lower end of pure sativa) basically every day, throughout the day. I design circuit boards, do mechanical design, fabrication, assembly and test, and write Python code all with some level of marijuana in my system. (Obv have to be careful about dosage or I will be unable to work until it wears off.) In the last three months I designed a four axis robot arm with four custom planetary gearboxes of my own design.

I know that my marijuana consumption is not ideal for my health and I aspire to reduce it eventually. But I have been doing this for years and I’m getting better at designing and building robots, not worse.
It's also pretty straightforward to emulate a KMS server and activate Windows that way. Technically against the EULA, I'm sure, but Microsoft doesn't seem very motivated to do anything about it (certainly not for individual users).

Maybe these outages will make people realize how dependent they are on a few monopolistic companies.Not only these will make rise of competitors but also hopefully make people's information more independent
It's probably more about the standard becoming a moat.

20 years ago IBM PowerPC was still a contender too. With Apple no less.

The x86/64 solo reign was more like 15 years.

But I miss it too. The 90s with all its amazing architectures. SPARC, Alpha, MIPS, PA-RISC, PowerPC. I still have several of those here at home :) Computers have become boring and it's nice ARM is shaking things up.

I wonder if M1 will ever be fully supported though. With full unrestricted video, 3D and AI acceleration. There seems to be a lot of Apple secret sauce in these processors.
100% agree.

This document shows practices of sed, but the author doesn't seem aware of best practices. A sed script starting with '#!/bin/bash' is a bad practice.

high CPU usage by kernel_task is caused by high Thunderbolt Left Proximity temperature, which is caused by charging and having normal peripherals plugged in at the same time.

Same here.

I’ve been thinking it’s a sort of “escape from the void”. When there’s nothing that particularly needs focus, there’s a feeling of wanting to escape from the discomfort of the silence. When I truly have no plans, I find myself seeking out lots of cheap fillers - HN, reddit, snacks.

As Blaise Pascal said, “ All of humanity's problems stem from man's inability to sit quietly in a room alone”.

The question is why? Why is it so hard to sit quietly in a room alone? What exactly is it that we’re trying to escape?
