I have absolutely 0 mathematical intuition or knowledge these days. If I had to estimate how much I’ve retained, I’d say most of elementary school math and a tiny subset of middle school / high school algebra.

I never really failed it, but towards the end of high school in cal us and related courses, I suffered from a “don’t care” attitude combined with teachers who basically just passed everyone.

Now of course I find myself strong mathematical skills to work on the things I want, but the knowledge and intuition just isn’t there. I could likely invest in learning it, but it’s difficult as I not only have to worry about learning the fields immediately applicable to what I want to do, but having to go back through many years of subjects I forgot or was never taught and figuring out what the proper prerequisites I need to relearn. At that point it just seems so far away from my original need and such a time sink I’m not sure I could motivate myself to do it.

And on the intuition side, I am shocked by just how well people around me, even kids are able to grasp the more abstract mathematical concepts around programming. Things like category theory and such. It all sounds like a foreign language when people begin to discuss these things. Not the the more practical things are much better. I have failed to learn digital design a few times now because despite understanding all the primitive Boolean functions I can never on my own figure out how to arrange them into useful functions, simple or complex.

I agree that it's terrible that people did not read before tweeting.

I believe Greg was not saying Aditya was both incompetent and malicious. Greg was saying incompetent or malicious. The incompetence stemmed from how Aditya handled his static analysis patches: seemingly no manual review and no explicit statement that the patches were from a tool (which is apparently standard procedure).

I was looking for the (cbc?) story of a farmer in Alberta or Saskatchewan who was attracting beavers by this very method to reintroduce them to the environment, but I didn’t find it. Might have been CBC Ideas[0]. I’ll have to leave it as an exercise for the reader.

Could it be that the engineers need changes in order to deliver on a product they’re working on?

Being on an infra or platform team is always going to involve receiving a lot of demands from engineers, since you become the bottleneck preventing them from adding/modifying the overall system.

Genuinely curious to hear how engineers act entitled.
If you believe everyone’s memories you believe a lot of false things. Human memory is notoriously unreliable, and old memories are often patched together out of stories, dreams and entirely different events.

An Accidental Bootsplash
Malice implies that the intent was to cause harm, which there was not. The execution was negligent, at worst, but not malicious.

And you've ignored the rest of the post, which is that the patches that Greg was blowing up about had nothing to do with that research. Please actually read the whole post and try to understand the situation.

This entire thing started with Greg alleging that legitimate patches from a security researcher were malicious. They were not. Previous patches, from another group, a year ago, are what you're referring to.
I might be biased, but this assessment confirms the suspicions I had when I realized it was businesswire.com who published this press release.
His supervisor published the hypocrite paper with the introduced vulnerabilities so they are far more linked than just both being at UMN.

This is the popular understanding. I've seen arguments against this claim. (e.g. "er" are frequent in english, and adjacent in qwerty).

Well, the article indicates the increase was 1% in amount of congestion, and 4.5% in duration. So, I suppose that means people in traffic are in traffic longer?
Honestly, UML would have been awesome for backend architecture. Most backend architecture I see are logos next to boxes connected by arrows, which is fine for high-level but extremely difficult to automate

When I was in Canada I was talking to farmers who routinely trapped beavers and blew up their damns with dynamite. Otherwise they'd flood huge swaths of farmland.
Yes, this is not an uncommon technique for doing a "true hard reset" on electronics that are normally "soft-off". The idea is that pressing the button will cause it to try to turn on if there's still some charge left, which then drains the charge away quickly.
Enabling the WSL to include support for Wayland and X server related scenarios
An additional issue is that some sophisticated C++ doesn’t always translate easily into other languages. It isn’t just a fairly direct reimplementation but a legit redesign. That will be a bug factory, especially for the kinds of codes that tend to be difficult to translate, as proving equivalence won’t be trivial.
Perhaps we'll find out more details when the research group and university start to perform those actions.

I wish this were true. We're not even that close to getting regular people to use Signal, at least not in meaningful numbers. Perhaps your friends family are more tech-savy and privacy-focused than mine, but it's like pulling teeth to get folks away from iMessage or Whatsapp.

> Apple countered by arguing that “no reasonable consumer would believe” that content purchased through iTunes would be available on the platform indefinitely.

I find myself reasonable and if I purchased something, I expect it to have access to it as long as the platform exists. And if they are planning to go out of content hosting business or close one’s account, then I would expect that they provide a reasonable notice and a way to download all the purchases content.

What Sidney Powell is trying to do in the proceedings is to argue that the allegedly defamatory statements are part of legal proceedings. Legal pleadings are by definition protected speech and cannot be defamatory.

The problem she faces is that, while the lawsuits themselves are protected, she held several press conferences and made the same speech in other venues where it is not so protected. Furthermore, by making essentially the same speech in legal pleadings, portraying the speech as opinion or hyperbole and not factual statements (the usual defense in a defamation lawsuit) would mean admitting to committing sanctionable offenses in filing those pleadings. But they're trying to still play that defense as well, which leads to the awkward conclusion "it's so outlandlishly false that no one would believe it to be fact, merely a fact we're arguing is true in a court case," which kind of makes it more likely they get slapped both with the sanctions for making false statements before the court and being the rare defendant to lose a defamation suit.
I think their definition of Net Revenue Retention (at least my understanding) is wrong as it includes growth from net-new MRR. This confounds retention with growth and isn't really helpful to answer what you really want to know: where is the revenue coming from? Retention IMU should be Past MRR plus upgrades less downgrades less churn (divided by past MRR). It explicitly does not include new customers.

Some of the other metrics are not the priority ones we look at either; your core measures really depend on if you looking for profitability or growth.
Hi, I wrote this post and I've come to agree with you. That's all. :-)
Grantham is always brilliant, but this interview is landmark. Markets for assets have become unhinged. He articulates the dynamics with perfect clarity.
My base stress level improved tremendously when I gave up iOS development and went back to the web. I don't have to deal with frustratingly broken tools every day or hold my breath every time I publish an update in case some random app store reviewer is having a bad day. Never again.
My own opinion as well as speculation:

IN THE US:

Public transit suffers from under funding and a general lack of civic planning (at least at macro-scales).

Public transit and all other public _spaces_ also suffer from lack of social safety nets at a national level. Defacto, they are where the displaced and under-served end up, because they are unable to go anywhere else. Everyone else with options either doesn't need to travel, or uses personal transport when they do. This exacerbates the issue of lack of funding through lack of use.

In the United States there is, an accurate, perception that on public transport someone is more likely to be exposed to crime, unwanted scents from the unwashed or the uncouth in personal hygiene (too much Axe (which is any), etc), or particularly during the pandemic, unavoidable social mingling.

In urban cores this might be different given the lack of cars and denser service. However around them the only well serviced customer are business persons who commute down town early, and then back in the evening.

In the suburbs and outlying areas there's either service far too infrequent to be a reliable choice or none at all; and often that service cuts off too early in the evening.
I just tried this on a laptop that died 5 years ago. Same symptoms - one day it got really hot and then was dead dead dead.

Spent hours disassembling it and probing various test points, all to no luck. It seems the issue was somewhere before powering up the CPU, and therefore kinda out of my expertise.

But this method seems to have brought it back to life.

Shame I've now cannibalized the screen and trackpad and CPU heatsink :-(
well i've seen it used "enthusiastically" for the lack of better word, i.e. once someone on the team starts using one header, with some relatively well proven and robust feature (like smart pointers), it creates a temptation for them and other team members to use anything else available in that giant library "for free".

And some features there could be more experimental in nature and some are either not intended, or not really needed for a simple use case you have at hand, so unless you veto each new #include by a panel, it becomes a giant cluster fsck full of infinite permutations of advanced, and poorly understood features which creates very fragile foundation for the project and maintenance nightmare.

Since the good parts of Boost are already in STL, i always recommend to just stick with (very minimal set of) STL, don't use what you don't need right now, and avoid the temptation to throw every available library or "neat" feature at a problem (which might save a bit of thinking time short term but open a can of worms long term)
I would suggest as an alternative to a refund a way to download you content with reasonable notice(30-60 days) in open formats.

ETH proof of stake is already live since December 1st, 2020, and it runs as a separate chain at the moment.

Why half the time? I'd expect that Uber tries to allocate a nearby driver, so that most pickups are near the last drop-off.

And of course with Uber Pool and Lyft Line, there may be only a slight detour for pickups.

This situation seems better than taxis, which drive an empty car around when they're NOT EVEN on their way to pick someone up. They'll just drive around and around waiting for someone to stick their arm out.
>don't know if they were more like tamagotchis.

They were and are! (They're still releasing new models, at least in Japan.)

But yes, the Digimon v-pets were definitely marketed as basically "tamagotchi for boys" and the gameplay is very similar.
Plus, this would a contract of adhesion—and courts hate contracts of adhesion and try to interpret them in favor of the consumer as far as possible.
A pay for access to content model would really only work if it were frictionless. If you have to decide before you read, people would simply say no. If you pay after you read, people would probably say no, too.

On the other hand, in the before times, people paid by the minute to a network provider (such as Compuserve, Genie, AOL, etc) as well as to their phone company to get online. I might consider paying per minute to access some high quality journalism... But then again, probably not, I'm cheap.
If this is going to work from my boat at some point, I'm never setting foot on land ever, again.
Rich Hickey and Clojure have a low-tech solution for you: use maps. This “wiring through all the layers” problem is basically self-imposed by the use of static typing for data objects. Instead you should mostly pass around maps, validate that the keys you care about are present, and pass along the rest.

Of course your Java peers aren’t going to be happy about this, so in some ways a new language is needed to establish a context for this norm. But the limitation isn’t physical, not even in Java.
> Another one is that single precision floating point doesn't have enough precision to represent both planet scale and human scale in the same coordinate system (let alone solar system scale or galaxy scale), yet GPUs don't support double precision well.

Could you do double-single computations on a GPU? (By that I mean something like double-double arithmetic, only with two singles instead of two doubles.)
Do you have any insight into why the machines are broken so often then?

No, Aditya's reputation has suffered because he is associated with the University of Minnesota. This is what happens when someone screws up, then all their associates get tarred with the same broad brush, no matter how much they were involved.

I'm familiar with a case where a faculty member engaged in a case of autoplagiarism and submitted the same paper to two high-profile journals. His graduate students had trouble publishing in reputable journals for years after, and he also earned himself a ban from the national funding agency.

For that kind of breach of trust retribution is savage, and that's why you don't engage in it to begin with.
I doubt its anything thinkpad specific, unless someone can find a datasheet for the parts involved.

This sounds like a sequence designed to get people to wait long enough until the computer is fully drained of power, causing any latch-ups to clear. Sometimes a tech (or their troubleshooting tree) will have you unplug/debattery the computer, then read out serial numbers or something to accomplish this task without you noticing. I bet if you just removed the power sources, then waited a minute timed by a stopwatch it would work just as well.

There is a art to making troubleshooting steps resolve a problem without the customer needing to tell the technician they made a bone headed mistake. Really well written steps like these ones make it so the customer is completely unaware that the actual problem was that they did not wait long enough.
>Usually, digi was a more complicated knock off that fit a different niche of people who like battling Pokémon.

"Knock-off" is a strange description for a product made by the same company as the Tamagotchi. Can they make knock-offs of their own product?
Sounds like more of an acquihire than they actually wanted the app, based both on how much they put into it in resources after purchase, and how much they sold it back for.
Apollo 8 proved it possible, actually. ;) The onboard sextant worked perfectly.
Yes, it works, if you can jump 2^64 iterations quickly. This is how xoroshiro achieves multiple streams. The PCG32 or the xoroshiro method guarantees independent streams. Using high bits in seeds doesn't have the guaranteed behavior. When you have many streams, stream collisions may become an issue.

One note about the aero research rules in F1 which makes this post particularly interesting: there are limitations on the amount of CFD simulation time teams can use.
If map and reduce were design patterns, you’d be writing out the iteration bits every time you used them. Instead map and reduce are abstractions, and you only have to plug in your unique functions and values.

They aren't "broken". It's operations failures. The basic fact of

1. Keeping the machine full of the right amount of product to complete it's nightly heat cycle

2. Have someone trained to fully clean the machine every 14 days

Is a burden too great for many franchisees to bear. The turnover is too high and investment in people too low to keep them operational. Nothing about them is "broken"
Public SaaS companies calculate dollar retention at least 15 different ways so there are many ways to do it. But I do agree with you.

Hired also doesn’t make it enforceable either. I received an offer lower than what the company said it would offer in the beginning.
That's interesting. It doesn't sound that simple though, I imagine there are some gotchas with that. They are probably constrained by what Unity allows.

In my custom engine I did the world to camera transform for each object on the CPU in double precision, essentially making the camera the origin for all subsequent single precision computations on the GPU. That works for small objects and even large objects that are split into small parts, like a planet split into LOD terrain tiles. But it didn't work for orbit lines because they are a single object at planet scale that you can zoom in on to see at human scale (I didn't have an adaptive tesselation system like the one in the article).

It also wouldn't have worked for galaxy scale, where even double precision wouldn't be enough. I don't know exactly what Celestia and similar "entire universe" apps do. Emulated quad precision floating point?

Edit: I just realized that you are talking about precision issues with the physics engine, while I'm talking about precision issues in the rendering engine. Related but slightly different. Physics engines aren't constrained by GPUs and can use double precision throughout. But they often have stability issues even in normal circumstances so I can certainly imagine that solar system scales would be a problem even in double precision.
Wow.

For a service that should have global reach, these are mostly in the US! I'm a lot more excited about LEO broadband compared to 5G. Sounds like a career change worth pursuing, even if you are halfway around the world.
