On maybe the third day of my first programming job, a colleague pulled me aside and said “don’t give me ‘shoulds’ and ‘probablys’. You need to sound confident so I can know to trust what you’re saying”.

That guy was a bit of a dickhead in general but there’s a lot of truth there. To the question “what’s the expected impact of this change?”, “None.” is a good answer. “Well it should work…” is not useful feedback and a good Operations Manager will rightfully reject the change.

Of course it is better to be hesitant than falsely confident, but far too many (software) engineers hide behind indecisive language to dodge the necessary hard work of validating their hunches. If you didn’t test your shit fully, just say so. If you’re right, say it. Personal ego doesn’t belong in an engineering discussion.

I think the premium thing is a channel option. Some channels consistently have it, some don’t.

Regular YouTube 1080p is bad and feels like 720p. The encoding on videos with “Premium 1080p” is catastrophic. It’s significantly worse than decently encoded 480p. Creators will put a lot of time and effort in their lighting and camera gear, then the compression artifacting makes the video feel like watching a porn bootleg on a shady site. I guess there must be a strong financial incentive to nuke their video quality this way.

Technology Connections and Hank Green have been shouting this for a while, but that whole issue is way overblown. Some first gen EVs around 2010 had issues, but every major manufacturer since then has way exceeded expectations on battery lifetime thanks to advanced BMS and thermal controls. Car batteries don’t just rapidly degrade out of the blue, the tech has nothing in common with what’s in your phone. But public sentiment has not caught up because most people think Li-Ion = smartphone = dead after 2-5 years, so second hand EVs are way undervalued. Which is great for buyers.

It’s not like you can’t easily total a second-hand ICE by mechanical failure. Just ask anyone who own(ed) a puretech engine. If you went by manufacturer recommendations, the fucking thing might just eat your timing belt one day and grenade itself. And there’s no way a full engine swap on a 5-10 year old economy car is economically viable.

There’s always something that could go wrong when you buy a car. Unless you get comprehensive insurance and warranty, you need to accept the fact that losing the entire car to an accident, catastrophic mechanical failure, or theft is always a risk. If that’s too much anxiety to deal with, get a lease.

THANK YOU.

I migrated services from LXC to kubernetes. One of these services has been exhibiting concerning memory footprint issues. Everyone immediately went “REEEEEEEE KUBERNETES BAD EVERYTHING WAS FINE BEFORE WHAT IS ALL THIS ABSTRACTION >:(((((”.

I just spent three months doing optimization work. For memory/resource leaks in that old C codebase. Kubernetes didn’t have fuck-all to do with any of those (which is obvious to literally anyone who has any clue how containerization works under the hood). The codebase just had very old-fashioned manual memory management leaks as well as a weird interaction between jemalloc and RHEL’s default kernel settings.

The only reason I spent all that time optimizing and we aren’t just throwing more RAM at the problem? Due to incredible levels of incompetence business-side I’ll spare you the details of, our 30 day growth predictions have error bars so many orders of magnitude wide that we are stuck in a stupid loop of “won’t order hardware we probably won’t need but if we do get a best-case user influx the lead time on new hardware is too long to get you the RAM we need”. Basically the virtual price of RAM is super high because the suits keep pinky-promising that we’ll get a bunch of users soon but are also constantly wrong about that.

Being able to assign a nameserver per interface with a domain wildcard is a fucking godsend. I use it every day with a hook script because my job uses some private domains but I don’t want to send my entire DNS history through the VPN. Now ~job.com goes to tun0 and that’s the end of it.

systemd-resolved is not perfect but with libnss’s overly rigid nature the only alternative for my use-case would be to recreate similar functionality to resolved with dnsmasq – which is just objectively worse especially when you want to use DHCP sometimes but not always. Why reinvent the wheel? resolved does its job and does it well. I had some issues with it a few years ago but have been using it for the past couple years without complaint.

??? Of course you do. Investors don’t just buy their way into hypothetical future profits, they buy control over the company. The specifics depend, whether it’s voting shares or the looming threat of debt collection, but the courts will 100 % enforce investors’ right to demand things from companies.

Furthermore the idea that publicly traded companies have some kind of obligation to make as much money as quickly as possible is a reddit-born myth. Shareholders will bring in a CEO, who will be tasked to do whatever and can be fired from the shareholders at any time. Grievous mismanagement and intentional damage can expose a CEO to legal action, just like intentionally destroying tools can expose a worker to legal action. But a CEO acting in good faith has no other obligation than to fulfill the tasks asked of them by shareholders. The problem is that goes wrong when large shareholders plan to sell their shares and need the numbers to look a little better to sell a little higher. But this phenomenon absolutely happens with PE as well – in fact it’s arguably way worse because publicly traded companies at least have legal obligations of financial transparency. Private shareholders can do whatever the fuck they want, including secretly selling their shares to Evil Inc. for them to strip the company for parts and not a single employee has the right to even know who the majority shareholder even is, nervermind what their plan is.

I can’t be fucked to find the graph but it’s true. The relationship between speed and exhaustion is highly asymmetric, going 20 % slower than your default walk is much more tiring than going 20 % faster.

It actually makes intuitive sense to anyone who hikes. Walking slow is like hiking downhill. You’re fighting your body’s natural cadence which requires extra energy that doesn’t go anywhere useful. Going faster also uses extra energy but it’s largely “useful” energy that spares steps. The extreme version of that line of thought is that I can run 10 km but not crawl 10 km.

Also fast walkers tend to… walk a lot, it’s a virtuous circle. It’s fine if grandma does a lap around the mall at 2 km/h, but I’ve been walking all day and I have more places to walk to afterwards and I ain’t doing all that at crawling pace.

Induction is objectively better than every other option for anyone connected to the grid looking to buy a new kitchen stove.

Unfortunately it’s one of these things that takes five minutes to explain because everyone has tried the Slumlord Special resistive stove and the general public can’t tell the difference. Those five minutes are why induction uptake is pathetically low compared to how superior it is in literally every way.

Same deal with people who would still buy incandescent lightbulbs if they could just because they don’t understand that technology has moved on from CFLs and to them it’s all “newfangled economic bulbs that can’t light for shit”.

Easier job to do when you’re actually getting reports.

• Reporting = this breaks the rules please moderate
• Blocking = Fuck them, even if they rechnicly abide by the rules I don’t want them near me
• Muting = I don’t want to see what this person does but don’t want to hurt them beyond that

It’s very funny that you can get ChaptGPT to spell out the word (making each letter an individual token) and still be wrong.

Of course it makes complete sense when you know how LLMs work, but this demo does a very concise job of short-circuiting the cognitive bias that talking machine == thinking machine.

It’s like every other media industry. The monoculture is dying. Everyone’s who’s “about it” is into niche subcultures and micro-celebrities you’ll probably never hear of.

There was a weird period of time from the mid-20th through the early 21st century where radio and TV had very strongly concentrated media production which made up most people’s media consumption.
For the last 15 years or so the tools of professional-looking media production for mass consumption have been available to anyone with a few hundred bucks to spare.

In some ways it’s a communist utopia. The means of production have been commodified so much virtually anyone can afford them. However capitalists have moved on from owning the means of production to owning the means of distribution (the platforms).

https://docs.python.org/3/library/argparse.html#argparse.ArgumentParser.add_mutually_exclusive_group

However I’ve never had to use that feature. Like I said it can make sense in specific contexts but it is a pretty strong indicator that you have built in a CLI antipattern or too much complexity.

Counterpoint: Yes, parse don’t validate, but CLIs should not be dealing with dependency management.

I love Python’s argparse because:

• It’s “Parse, don’t validate” (even supports FileType as a target)
• It enforces or strongly encourages good CLI design
  • Required arguments should in most situations be positional arguments, not flags. It’s curl <URL> not curl --url <URL>.
  • Flags should not depend on each other. That usually indicates spaghetti CLI design. Don’t do server --serve --port 8080 and server --reload with rules for mix-and-matching those, do server serve --port 8080 and server reload with two separate subparsers.
  • Mutually exclusive flags sometimes make sense but usually don’t. Don’t do --xml --json, do -f [xml|json].
  • This or( pattern of yours IMO should always be replaced by a subparser (which can use inheritance!). As a user the options’ data model should be immediately intuitive to me as I look at the --help and having mutually exclusive flags forces the user to do the extra work of dependency management. Don’t do server --env prod --auth abc --ssl, do server serve prod --auth abc --ssl where prod is its own subparser inheriting from AbstractServeParser or whatever.

Thinking of CLI flags as a direct mapping to runtime variables is the fundamental mistake here I think. A CLI should be a mapping to the set(s) of behavior(s) of your application. A good CLI may have mandatory positional arguments but has 0 mandatory flags, 0 mutually exclusive flags, and if it implements multiple separate behaviors should be a tree of subparsers. Any mandatory or mutually exclusive flags should be an immediate warning that you’re not being very UNIX-y in your CLI design.

I’ve been using the AI to help me with some beginner level rust compilation checks recently.

I never once got an accurate solution, but half the time it gave me a decent enough keyword to google or broken pattern to fix myself. The other half of the time it kept giving me back my own code proudly telling me it fixed it.

Don’t worry though, AGI is right around the corner. Just one more trillion dollars bro. One trillion and we’ll provide untold value to the shareholders bro. Trust me bro.

I don’t trust the US government to do literally anything right with this, and I’m kinda surprised Google didn’t already gift an underage child to Trump so he’d make the problem go away.

However a perfectly viable option that I’m sure the previous government looked into would be to entrust Chromium (which is Open-Source though not copyleft) to a new, independent nonprofit made of Google’s former chromium team led and paid for by a consortium of the major commercial chromium users (Google, Microsoft, etc.). It would be in everyone’s best interest to share the relatively small financial burden so that Chromium can remain decent and competitive.

This wouldn’t be anything revolutionary. This approach of financing an independent open-source project as a “common good” is basically how the Linux kernel has been developed for many years now, most Linux code is written by corporate sponsors.

North American trees species have evolved to have more vibrant fall colors than European species.

So you’re basically proving that British guy’s point that yes, they are a different color but no-one believes it because they think they know what fall looks like in temperate climates.

I am not looking for a compromise. I listen to my high-quality digital library on shuffle most of the time, and am very well aware that my phone allows me to access orders of magnitude more music than even the most compact CD player.

When I do listen to my favorite albums as LPs, the clunkiness and the artifacts are part of an Experience. I can listen to exact copies of the digital masters of those songs any time I want to, but sometimes we do things BECAUSE they are not maximally optimal. Sometimes I want to take a walk alongside the river and get my feet a little bit wet even though I could have worn boots. Feel a little something, you know?

The EU is currently deepthroating Trump so hard that it’s completely out of breath and all our clothes are ruined.

With how volatile Trump is this could change literally anyday, but with the current political equilibrium all google would have to do is gift trump a shiny golden thing so he makes a threatening remark about gas exports and the EU would go “uwu yes master right away master, do you want to fuck my gaping asshole while you’re at it?”.

This kind of shit happens with a similar frequency… on Arch Linux. It’s rolling release, shit happens sometimes. archlinux.org’s homepage actually lists past major packaging issues.

Debian however is rock-fucking-solid. But so is Windows Server, I hear. The problem is that Microsoft is treating Windows Home/Pro like a rolling release distro, and the users are guinea pigs. I guess Microsoft is right though, their users will eat it up 'till shit is spilling out from both ends, so why bother?

Well you hardly have a leg to stand on about “feeling superior” when you’re out here being smug about criticizing harmless tastes.

I don’t see how listening to vinyls in the privacy of my own home is considered performative, but if that’s the only reasoning you’re willing to entertain… Well go right ahead, I thought I made a good case for it but I guess I was wrong and I am buying vinyls for the clout.
