eMicro escooters are light and pretty powerful, but range is not the best.

Egret escooters have better range but are heavier.

Both brands are well built and durable, but not cheap.

I've had my Egret 10 for over a year, use it every day on rough roads with heavy loads and it's held up nicely. I did break the trigger going over a pothole, but was able to fix it myself. Otherwise only changed the back tire and brake pads (standard parts).
"With /proc/sys/kernel/pid_max defaulting to 32768 we actually ran out of PIDs. We increased that limit vastly, probably way beyond what we currently need, to 500000. Actuall limit on 64bit systems is 222"

Time to start thinking about 128bit systems!
> With a good cassette deck, brand new chrome tapes and Dolby noise reduction, it's hard to hear much of a difference between that and a digital recording.

When I was in my 20s, I could easily hear the difference between cassettes and vinyl on the same stereo. The cassettes had an annoying SSSSSS and the crispness of the notes was mushed over. The 12" vinyl singles sounded even better, especially the "promotional" ones.

Now that I'm older, I no longer hear the difference and so it doesn't matter to me.
Seems like the widespread adoption of USB-C has been a bit of a mixed bag. The sheer combinatorial explosion of combined cables, accessories and devices has created a lot of surprises for manufacturers. I really like having one cable standard that can do so much, but I hope situations like this become rarer over time.

This is a nice article. For those who have not yet read it (it's short, read it!), a one-paragraph summary: the author starts with a list of random numbers. Visualizing it (plotting the numbers, with the list index on the x axis) suggests / leads to (for the author) curiosity about how often numbers repeat. Plotting that leads to the question of what the maximum frequency would be, as a size of the input list. This can lead to a hypothesis, which one can explore with larger runs. And then after some musings about this process, the post suddenly ends (leaving the rest to the reader), and gives the code that was used for plotting.

This article is essentially an encouragement and a reminder of our ability to do experimental mathematics (https://en.wikipedia.org/w/index.php?title=Experimental_math...): there's even a journal for it, and the Wikipedia article on it is worth reading (https://en.wikipedia.org/w/index.php?title=Experimental_Math...). See also (I guess I'm just reproducing the first page of search results here) this article (https://www.maa.org/external_archive/devlin/devlin_03_09.htm...), these two in the Notices of the AMS (https://www.ams.org/notices/200505/fea-borwein.pdf, http://www.ams.org/notices/199506/levy.pdf), this website (https://www.experimentalmath.info), this post by Wolfram (https://blog.stephenwolfram.com/2017/03/two-hours-of-experim...), and there's even book by V. I. Arnold (besides a couple by Borwein and Bailey, and others).

Especially in number theory and probability, simple explorations with a computer can suggest deep conjectures that are yet to be proved.

You probably know this, but a lot of studies back you up. Being smarter doesn't necessarily make you more likely to be right, but it makes you a hell of a lot better at rationalizing your position and persuading others. Also, that comment about the "old guy with an inferiority complex who sneaks one really profound comment in every meeting" really hit home. We have that guy on my team too. You have to wonder what's going on when those guys are sitting in the corner and us blustery people are doing all of the talking.

Really nice writing style on this article.

It covers everything that needs to be covered, but it also gets right to the point. Yet without being overly terse or dry.

And it explains everything clearly. So often the writer is good at understanding an idea but not conveying it. This lays it out where it's easy to pick up.

The second album I ever bought was Fragile by Yes. There was a deep scratch in the first song on the second side, deep enough to cause skipping and jumping.

Even on the CD version of that album, I still "hear" the scratch. The unscratched perfect version sounds wrong. Can't get it out of my mind.
Yes, cost is always a factor. That said, if the room control was affordable, would changing the space be an objectively better solution than changing the display?
MajorBBS was a whole other ballgame when it came to operations... Cost of the software, digiboards, modems and multiple lines generally put it outside of the reach of the teenage sysop market... it also tended to lend to commercial operators who flipped into the ISP space (or at least it did on the east coast)
Seriously, if people are this determined to tie themselves into knots trying to defend their ridiculous bias that smooth motion = soap opera, it kind of makes of despair about whether its actually possible to change anybody's mind about anything ever.

Luckily the fact that tv's with motion smoothing are selling suggests that the rest of us have spent the 2 minutes necessary to get used to it and realized that it's superior.
> The correct procedure has been observed to work, but not everything that is observed to work is correct.

Procedures are neither correct nor incorrect but rather effective or ineffective. Whether the explanation is correct or incorrect is irrelevant if the procedure is effective. Of course we would prefer to have both the effective procedure and the correct explanation but if we insist on only applying procedures with correct explanations we are not doing the best we can.

So, I would extend the proper response to, "This tends to work, we don't know why, but you should try it."
I spent a week in Copenhagen a few years ago and, while it was incredibly expensive, I was very impressed.

But on further investigation I discovered it was almost impossible to get a long term rental there. I read that Danes would put their newborns on wait lists in hopes that they might be eligible for an apartment when they left home 18 years later.

Copenhagians, is that really true or just Internet Hyperbole?
> it's inefficient to split water to produce hydrogen

You also have significant losses when you convert it back electricity/heat with fuel cells, or burning it.

This is really interesting. I wonder how much this helps offset the losses mentioned above?
Shared electric scooters are undoubtedly pretty damned dirty, due to the very short working life of the scooter and the fuel use in collecting and returning the scooters.

Owning an electric scooter looks pretty damned clean - ~200kg/CO2e to manufacture the scooter, plus 0 - 300g to generate enough electricity to charge the battery.

Thousands of managers. Not all are honest. As an example, I toured an FC once and there was a still boxed perfect $9000 TV sitting in the damaged area. Most retail has a policy that damaged has to be destroyed. In reality places I have worked, managers came through and picked through it.

This is nothing new for retail or warehouses. If a manager is suspected of helping thieves, they might be moved around instead of fired due to politics.

I switched from Chrome+Goog to Firefox+DDG...but had to dump DDG a week later. The results just aren’t anywhere near on par with google. The results have no dates so I’m constantly served results to outdated tech info (5 year old posts about Cassandra, no thanks DDG), and they only present 1 link to an article vs the more info-dense google format with 1 primary link to say, StackOverflow, and 4 more possible hits smaller just below it presented as “more from this site.”

Basically I get more done faster with google search, however much I hate the goog panopticon. I’ve also switched to Apple News and Maps so I’m very much trying to dump goog, but search is where they still really excel.

I do wish I’d come back to Firefox sooner though, absolutely love it post quantum.

What are you talking about? In the US ethanol production is up 20+% over the last ten years.

https://www.eia.gov/todayinenergy/detail.php?id=32152

Corn ethanol is not a very good way to reduce co2 emissions. It only yields about 1.5 units of energy per unit of energy invested vs 7 for Brazilian sugar cane ethanol. In the US it's a farm subsidy program ( in Germany their big corn subsidy is turning it into methane). The reason you think it disappeared is that everyone now realizes it's justifications don't make sense but farm states are too important to take a subsidy away from.
This seems like an anti-trust issue.

> "the ability to do X without legal consequence from the government"

That would be, 'it's not illegal'. I think there are four different things in play here.

a) a fundamental right, because you are human; this is something that a government ought to respect.

b) something which the government has said is legal to do; i.e., something the goverment says is OK.

c) the responsibilities which a citizen must bear; or, what happens if you break the law

d) the rights to which a citizen is entitled: the respect which the government actually gives you.

I guess I conflated some of those things.

> If you define "right" as "you have the ability to do X and face legal consequences for having done it,"

That would be a combination of (a) and (c), where you have the human right to say what you please, but as a citizen you have to deal with the consequences. That's different from, say, murder, where you don't have the human right to murder and you also broke the law (and have to face the consequences). It's a trivial distinction in most cases, but not all.

For me it depends on the company. The large, "everyman" companies, the Comcasts and T-Mobiles of the world, have always had me dealing with a customer service representative on a script giving me friction about something that is completely within their reach, but they're made to be unhelpful until you cross some threshold. Start off polite, but the second they tell you something "isn't possible" you drop the polite tone, get stern, ask for supervisors, etc. That isn't to say swear and insult, and you should reset the politeness each time you get a new person.

In my experience anything even a little more "targeted" tends to have more reasonable customer service. I've had good customer service experiences from major sportswear brands, and we're not talking crazy high-end, boutique brands but major, publicly traded companies. That isn't to say they will just cater to your every whim, no questions asked, but if you have a legitimate grievance they will handle it without ruining your day.

Some companies care about reputation and customer satisfaction, and some just count every bean.

Scalable architecture: Celery tasks vs. long running microservice
NOTE: TASK = makes some rest calls to a IAAS provider, updates various tables in Mysql database

I am currently using celery to manage the task queue. We have large (500 tasks per minute) number of adhoc task requests and long running periodic tasks. After some profiling and instrumenting the workflow, the task launches is adding latencies to the background job to accomplished. Also, based on celery beat, periodic poller tasks are long running ones, taking up around 6 to 8 minutes in duration, with periodicity of 10 minutes.

In the above scenario, would it be better to move to microservice's (async i/o, leaning towards starlette) that would be listening/subscribed to topic, pulls the request, completes it, and then waits for next request. Microservice runs forever. For every periodic task (celery beat), there is a microservice replacement. planning NATS for pub/sub

What would be the best approach for a scalable architecture (from 500 per minute to 4K per minute)?
Less cynically, it also increases the odds of finding good employees. A "bottom 5%" worker is statistically less likely to suddenly rise to the top of the pack than a new hire is to produce at that level initially. And, more cynically, that remains true even if there's significant measurement error in identifying that 5%.
Sorry you had to go through such obviously bad management. Just to give some context about how these guidelines are supposed to work at Google: being managed out for staying at Meets Expectations is something that's supposed to be only applicable to entry-level roles. (when I was there, this applied to the new grad T3 rank, as well as T4, I think this may have changed since I left to be just T3).

But at an entry-level rank, it is possible to get good ratings and even get promoted if your product hasn't shipped to customers yet (and I would do this with my directs routinely), as long as you are delivering milestones. Part of the definition of T3 is that you cannot yet independently work on a project, ie you need help from senior devs to get things done, and IMO if you stay at this level for more than 1.5 years (3 reviews), and there are no other extenuating circumstances, it's appropriate to consider if the company is a fit.

At more senior levels, you have to show business/customer impact to get promoted, but there is also no notion of being managed out for meeting expectations.

Of course, these guidelines aren't always implemented or communicated equally across the company, to say nothing of other companies that copy only parts of the process.
Oops. Went a bit on autopilot with that one.

I have to agree with some of the commenters that your write-up is pretty bad, because far too general for such a well studied problem.

Let me try to help you along in your thinking: The tragedy of the commons is not a generalized version of the prisoner dilemma. I guess you meant to say a prisoners dilemma is a more generalized version of the tragedy of the commons. This is however also not true. Logically because there is no sensible pay-off where everybody defects, but the other player. The commons would be largely destroyed way before everyone gets their pay-off so all the players would never collectively decide to do that (and decision is a integral part of the prisoners dilemma). You could make it into a NxN dimensional prisoners dilemma, but that is not useful for another reason. The tragedy of the commons is about future benefit (keeping the commons so everyone can extract more than they could individually at a single instance) a prisoners dilemma is an instant game. You could model the tragedy of the commons as a repeated prisoner dilemma. The problem is that free riding is not a rational option if you repeat it often enough. In the real world free-riding works, because we expect to play a limited number of rounds and in the long term we are all dead. The number of repetitions one expects to play is however not the same for all players.

Limiting defection is in this case not external to the tragedy of the commons, as any way to resolve the prisoners dilemma is, because it reduces the pay-offs the participants get. Preventing defection costs and there is a balance to be struck to the costs to preventing an additional free-rider and letting him free-ride. There is also a moral component to this. Limiting defection means also being able to limit entry. The commons has de-facto become 'our commons'. There is the description of a 'mutual protective agency and one of the most common is the state.

Use a real video player from anywhere in 2002 or so onward, e.g. mplayer, xine, vlc, Media Player Classic (mplayer is the fastest), with a real video file on your local disk. Fast forward and rewind are nearly instantaneous.

For audio, look up a really old program called alsaplayer that could play forward, backward and at any speed.

It's not "digital" that makes rewinding and fast forwarding crap on crap devices and services, it's the lack of care for user experience.
I get it, but I still prefer CDs because the sound quality is better, I can losslessly rip them, and they don't break. It's a little frustrating to me when the only physical version of an album is a cassette tape.

There are cases where signals might be dropped (though I'm not sure if SIGKILL has this problem off the top of my head -- some signals have special treatment and SIGKILL is probably one of them). And to be fair this is a more generic "signals have fundamental problems" issue than it is specifically tied to cgroups.

It depends what you need. If you don't care that the kill operation might not complete without unfreezing the cgroup, then you're right that it's not an issue. But if the signal was lost (assuming this can happen with SIGKILL), unfreezing means that the number of processes might not decrease over time and you'll have to retry several times. Yeah, it'd be hard to hit this race more than ~5 times in a row but it still makes userspace programs more complicated than they need to be.
