Everyone using cell signals takes up that much bandwidth that could otherwise be used for emergency personnel - I'm not saying not to use cell towers, I'm just saying that if you could choose between the two with no penalty on either, wi-fi would be preferable.

Also I would think it's far cheaper energy-wise to transmit the signal from my living room to my study rather than beaming the signal from a cell tower miles away. I could be wrong.
Who said anything about costs at the margin, i.e. 95th percentile?

You've just 'moved the goalposts' across the field :)

Bandwidth is a commodity like anything else and has underlying structural costs - it's far from free in any sense of the word. Even at the 95th percentile, as you say, there's no guarantee that there's unused bandwidth at all.

>If we want security standards, they need to be legislated democratically and applied to all devices -- not left up to consumer choice.

I get where you are coming from, and forgive me for going all libertarian but... I have less than zero trust in governments (especially mine in the UK). They don't understand tech. They don't want or try to understand tech. They have zero interest in personal freedom or autonomy.

If the UK government did this, I'd go out of my way to find a "non secure" phone as anything they licensed would just have massive insecure backdoors and probably wouldn't actually work as a phone...

Sorry for the rant. I'd honestly like more security in my devices...
This is entirely anecdotal, but I know six people who've quit either heroin or prescription/illicit oxycodone usage via Kratom.

The only real problem to Kratom is that there is no standardization to potency or means of labeling.

The percentage content of the active alkaloids in Kratom (Mitragynine and 7-Hydroxy-Mitragynine) can vary widely, with the stuff sold in gas stations and smoke shops being particularly low-potency or volatile.

The worst that will happen in the event of a Kratom overdose though, is horrendous nausea and vomiting that will make you wretch at the sight of the stuff for a good while.

Another personal anecdote, I have been a daily user for several years and had periods of weeks/months without use due to inconvenient life circumstances (traveling, too busy to buy more, etc) and never felt any ill effects from sudden cessation. Some people online report the opposite, though I suspect this might be largely psychological.

I don't know if you guys are aware of it, but two other overlooked medications for opiate withdrawal/recovery are Baclofen and Loperamide (yes, Immodium, the drugstore constipation medicine).

Immodium is active at the mu-opiod receptor but does not cross the blood-brain barrier, and so is not psychoactive. This can help to ease some of the withdrawals without risk of relapse.

Baclofen is mildly psychoactive but helps with opiate and benzodiazepine or other GABA-ergic drug withdrawals, with much less of the risk factors associated with traditional medications like methadone or buprenorphine.

Do you think these companies will continue to exist if they fire all the employees who get sick from the virus? Do you think these employees will survive without their paychecks?

Do you believe that anything benefiting "corporations" goes directly into the pocket of evil 1% CEOs and confers no benefit to employees? You probably work for a corporation. Corporate well-being is employee wellbeing because corporations are staffed by people.

Makes sense. There is some logic here. My main plan was to include ranges of stats as they come available and allow for people to play with the maths themselves so they can see what the rates could be if we knew them.

As there are already numbers out there that the press have released which are incredibly misleading as all the variables have yet to be calculated! I wanted to show this somehow too.

I am considering how to change it now. As the feedback here will help.
My perspective is that if you don't have competent people you can trust, then you might as well just pack it up.

Any technical or non technical person with any skill level can be competent in their role and trustworthy. It doesn't take years to develop that, it's a personality trait.

YCbCr (often called YUV for... reasons) and 4:2:0 chroma subsampling (half the vertical resolution for each plane of color information as for the brightness) are still the dominant color encoding used for digital video, HDTV, Blu-ray, etc.

The "CRY" model used by the Jaguar is fairly different than (though as you say, related conceptually in its separation of brightness/darkness information, of course). I think it basically just arose from a combination of big focus on smooth shading while keeping the color values workably small and fast to calculate on.

We have universal healthcare here in Canada, and we have basically no ability to care for sufferers of this pandemic. The U.S. has a lot more acute care facilities, a lot more response.

These policies are not a panacea, you need strong, accountable institutions for any of these things to be a benefit. Italy's hospitals have been over capacity for more than a week now, we will be soon, and so will the U.S.

Also, the U.S. defense establishment and industry is the source of many of the medical advancements you pay taxes for today, you don't live alone in the world. It is extremely childish to lash out, and call everyone a joke or a bully or an idiot, when these advancements are basically stagnant in your society, but people are willing to share them with you.

It's amazing how many of these recommendations are cloud based. If you have a cloud based box with bad security, anyone can get to it.

,,I avoided using any TypeScript- or JavaScript-specific language features in the''

I don't understand this part. The hardest part of compiling TypeScript to machine language is that you don't know what an operator does, as you don't know the exact type.

The book doesn't seem to have a specific limited scope to me, it seems to not choose between interpreting, JIT compiling techniques (optimizing/deoptimizing) or static compiling.

For a modern language I would probably use Rust instead (also stay with Intel architecture to make trying things out easier).

Anyways good luck for the book!
I was trying to emphasize the "based on personal experience" part. Of course you can still criticize the government. But elections have time and time again shown that the opinion of experts matters much less to the electorate than their personal experience. That's one of the reasons why the state of the economy is so important for the reelection of a president. That being said, if the US economy really does tank that could make his reelection more difficult but I think he can easily blame that on the virus.
Scientists agree that the Cambrian explosion caused an inexorable trend toward complicated nervous systems and I suppose therefore the initial flexible brain.

What I can't see evidence for is any notion that the brain was less flexible then became more flexible over time. Would it be incorrect to assert that it essentially began flexible, as a result of the appearance of nervous systems, and that's its primary property? Of course complexity increased with time. But did the flexibility also increase?
Yes, but the ones used at that point slow bacteria growt, but do not kill bacteria. They are therefore not considered antibiotics.

This sounds like a horrible way of running a society. This is like the government intentionally keeping the tax code complicated and making filing taxes difficult so companies can exist that then fix that problem. You are forcing the government to be immensely inefficient, for no other reason than that a small number of people can profit from those inefficiencies at the expense of improving society as a whole.

The government is gathering this data. Building your business on top of what another entity is doing (government or company) is always a risk. The exact same risk is taken if you build something on top of the API or data of another company. If you were to build a Twitter client and then Twitter would make their own client available you are shit out of luck. That is the risk you take when you build something on somebody else's infrastructure. I honestly don't see why the government is so special that it should be completely handcuffed and prevented from making meaningful positive changes in society just so the profits of a small amount of people can be protected.

If the government does something to improve society and you can't compete and make a profit, do something else. Would you start a firefighting service and then complain that the government offers this service for free? At that point, why have a government at all?

> Even if someone did genuinely want to switch, game development skills aren't necessarily easily transferable to other kinds of development, even if it helps.

This needs a lot of qualification. Even someone doing scripting probably has picked up coding fluency at least. Programming game engines and networking code is definitely tackling complex problems and could at least get a mid-level dev role. I think 3d asset creation is probably the most game-specific role, and even that is something that is used by special effects companies and design firms.

> That advice makes sense if a company you works for sucks, but if an entire industry is broken, you can't just tell people to suck it up and find a new industry.

You absolutely can tell people to suck it up and find a new industry. This mentality is why the game industry can get away with bad work life balance and low job security. Because people keep working there. If the game industry was starved for talent, then they'd have to offer better work experiences.

Not to mention you need teams to solve larger problems and/or support more customers. So OP's comment basically amounts to a cruel boast about the BS he doesn't have to put up with.

It'd be like telling a construction worker taking a water break: "That's the nice thing about the office jobs. No need to worry about hydration because I'm not out in the hot sun all day." I have a feeling this kind of observation would not be well received.
I routinely deal with large docker images, deployments, sometimes VM stuff, video files, model files. 20-30TB a month is considered a good month.

Remote desktop is also a consistent ~50-70Mbps per screen to have readable text while actively working on something (not using RDP/VNC).
Some proxies follow redirects... It enables devs to do things like "redirect request to the old server", and the client never needs to know (which is important for maintaining compatibility with an old api)

In that case, I'd expect all cookies etc. to be forwarded.
This is a great answer. I can see broadcasters buying licences from these teams, many of which are already owned by professional sports clubs.

Actually, given there's usually quite limited amount of attempts to guess a pin, I don't really worry too much about somebody just guessing a 4-digit pin. So what if there's "only a 100/500/800" of combinations to try, if you have only 3/5 attempts and only 1 phone you care to break into?

What I do worry about, though, is somebody watching me enter the code. And I don't have any paper and a promotion-site with a catchy name to provide, but it feels like catching somebody rapidly entering 4 pseudo-random digits is quite a bit easier than catching them rapidly entering 6 or 8 pseudo-random digits.

Is it hostile to call an attitude pretentious? I don't think it is... Some attitudes are pretentious.

What is pretentious about the quote that started this thread is the apparent belief that the kinds of people that do the things we talk about and admire on this site - building new kinds of software, starting growth-focused companies - are the only people "that are interested in ideas and making new stuff". I agree that there is a fairly thin stream of the building-software / starting-companies hackers that you're thinking of, but I see huge numbers of people from all walks of life being interested in ideas and creating things. Artists, writers, journalists, directors, bureaucrats, other types of business people, on and on and on. I think it is pretentious to look down our noses at pursuits that are not our own, that's all.

Your comment about hackathon event planning is illustrative: hackathons are honestly not at all where I would go to find the highest concentration of people creating interesting new things.

While I mostly agree with your comment, I do want to mention for anyone who finds it useful: there's quite a bit of modeling and simulation work in the scientific computing and research industry, including the US government and contractors that lends itself well to certain game development skillsets.

There's typically more focus on analytics and the science skills over artistic skills (sorry graphic artists, environmental artists, etc.) obviously, but backend developers in gaming often have a lot of useful overlapping skills and knowledge in terms of systems design, design patterns, sets of problems, etc.

Pay is good, work/life balance is great, intellectually stimulating, it's challenging yet enjoyable (though arguably not as fun as game development). In many cases, industry borrows or leverages work from the gaming industry quite a bit.

A step further and the defense industry/military industrial complex would also love to have more game developers--though tech has a pretty anti-government pro-business vibe overall (not surprisingly).
You are correct, my bad. But the production problem is what I described. The fungus is resistant but not immune to its own poison. It therefore proved very hard to produce commercially viable amounts. However once a mass production method was found, it was considered vital to the war effort and we quickly ramped up production.
What did zombie movies say about the 2000s? Nothing really.

Christopher Nolan’s dark night trilogy proved that these films can make money and be critically acclaimed.

Also is it really a craze? Christopher Reeves Superman was pretty popular so was Spider-Man and the Hulk when I was a kid. There were loads of movies and tv shows in the 80s and 90s with super heroes. I actually can't remember a time when they weren't popular.

The only difference now is Marvel is raking in at the box office. Is anyone else actually making money? DC aren't.
A slightly unfortunate trend in protocol design has been to prepend rather than append "info" fields to hash inputs. In other words, we tend to see

H(info || msg)

instead of

H(msg || info)

There are some good reasons to prefer append to prepend. One practical reason is that---related to what's discussed in the article---if we have to compute two values

H(msg || info_1)
H(msg || info_2)

we can do this with just one pass over msg (though admittedly in a non-blackbox way, namely, by saving an intermediate state of the hash computation). In contrast, for a well-designed hash function there should not be any way to save work when computing

H(info_1 || msg)
H(info_2 || msg)

and this lack of work savings is one of the reasons we tend to get prehash modes.

In addition, prepending to msg comes with a range of subtle security issues. As an example, for Merkle-Damgaard hashes like SHA-2 a proper prefix design needs to pad the prefix to a multiple of H's block length. This is to ensure that msg starts on a block boundary, which means that the hash digests as much of msg as possible in a single invocation of the compression function. Otherwise, if msg is short and it gets broken across a block boundary, this can make meet-in-the-middle--style attacks easier.

In contrast, appending the info string guarantees that msg starts at a block boundary, which is a small nicety. Moreover, one can easily guarantee in a black-box way (and independent of the value/encoding/&c of the info string) that msg ends at a block boundary (just by padding msg). This can be useful as a defense against some kinds of power analysis in the case that msg is a secret [1].

To be sure: appending also requires care---and care is always required when a Merkle-Damgaard hash! (Sponges like SHA-3 are more resistant to misuse.) At the very least, whatever is appended to msg should be prefix-free, and you will likely want to stop length extension attacks and related issues (see [2] for further discussion of this).

But in general my take is that the set of footguns for append is a subset of the prepend ones, and I hope that more folks go towards appending in the future.
