If it's really that trivial, the developer should be doing it so routinely that it should take less than 15 minutes to write unit tests for the take home exercise. Your statement literally demolishes any excuse for not doing it.
Show HN: Ethereum wallet with erc20 support built with React
I have a website hosted there, and manually renew a let's encrypt cert for custom domain pointing to it every few months. Unfortunately this involves removing and re-adding the custom domain.

I got a notification the cert was going to expire soon so I went through my usual renewal process, only to get redirected to the linked post from the new domain button immediately after deleting the custom domain. So the custom domain now 404s which is the last thing I would have wanted.

I'd strongly suggest a warning get attached to the delete domain custom domain button, or something similar, until this is fixed.

That is correct, but a non-distributed blockchain (i.e. something you use locally) sounds like a something that can also be solved by using a database or even your filesystem.

I'm not saying blockchains are bad technology, non-distributed blockchains can be a very good solution to certain problems, but it's not the "world changing" revolution many claim it to be.
Came here to ask just this. Even if the journalist/contractor were being as sloppy as possible with netsec, HTTPS would protect traffic between browser and Google's servers. But I'm guessing a place like Facebook would have proxy servers that could be inspecting the traffic if it were done at work? But if the employee took screenshots and waited until they were home to send them, he'd be OK, right? The article says he did this from his personal laptop:

> So when Zuckerberg’s admonition circulated, a young contract employee named Benjamin Fearnow decided it might be newsworthy. He took a screenshot on his personal laptop and sent the image to a friend named Michael Nuñez, who worked at the tech-news site Gizmodo. Nuñez promptly published a brief story about Zuckerberg’s memo.

I was thinking about dedicated application on phone for it instead of regular mail client. Mainly to provide easy interface to manage big amount of accounts, banning hosts etc. Also then the app could just use service like Google's Firebase Cloud Messaging. That would wake my app and then it would get a message. I hope that it is fast enough that a sending SMTP server would not timeout.

I don't really get this mentality. Yes, its good to have your home go up in value, but when you sell, are you moving to South Dakota? If not, then the houses your hoping to move into have ALSO gone up in value. The difference being that nobody can afford 'starter homes' at the low end, so people have a harder time selling them, and moving up to a nicer house.

The page tables and private memory shouldn't be needed for that.

But ultimately it comes down to the cost to complete some amount of work. Google also offers Nvidia GPUs in their cloud for training and should be able to compare the cost of using one over the other as both are supported by TF.

That is the ultimate guide on how good or not good the TPUs really are.

They're closely related though, since if the perf per watt is lower then Google can charge you less doller per perf. The price they charge you is ultimately tied to the operating cost.
Rumor is that an interposer alone is $20, and HBM is also rather expensive. Basically, you'd easily double the cost of these $99 chips if you put HBM2 onto them... maybe triple the costs if you consider that AMD should charge a margin and actually make a profit from these designs.

After that, the GPU would be too-strong on memory and too weak on compute. The minimum HBM speed 1024-bits / 250GB/s from one stack. Yeah, the same memory-bandwidth as a RX 580 with 2304 shaders, while the APU 2400G only has 704 shaders.

The Intel + AMD chip manages to solve the problem: the CPU, GPU, and HBM2 are all on the interposer. So the expensive interposer has a shared design. Second, the GPU is a fully dedicated Vega design that's roughly the size of an Rx 580. That way, the dedicated-GPU can "keep up" with the super-fast HBM2 RAM.

«It's simply a poor currency according to the metrics of price volatility, transaction verification speed and transaction fees.»

Bitcoin critics like you always focus on temporary issues. All the points you list are either being solved or fundamentally solvable. It's like criticizing cars from the early 1900s and missing the point that, obviously, they, like Bitcoin, will improve over time. For example:

• Volatility: on the long term it's declining because markets are getting deeper https://mobile.twitter.com/lsukernik/status/8649208737189519...

• Transaction verification speed: new technologies like Lightning Network make them instant; even a 0-conf non-RBF transaction is relatively safe to accept instantly for most use cases (eg. certainly safer than a CC transaction which can be fraudulently charged back.)

• Transaction fees: solvable by off-chain technologies like Lightning, or by increasing the block size (Graphene or UTXO set commitments make this scalable).

SQLite hadn't been kicked to the curb, the WebSQL API whose “standard” was essentially “act like version x of SQLite” was kicked to the curb.

The concept of WebSQL was good, but the standard itself wasn't great, and the absence of any intent to implement from other vendors or intent to improve the standard from those who had embraced it made it a dead-end standard.

It looks like you're mistaking "good programming" for "programming the same way I do".

In my opinion, there's no justification to describe his opinion as a "professional opinion" and himself as something as official as a "blockchain researcher". It's just an appeal to authority when there are no clear standards for what an authority is in this field.

>>Unfortunately for this central value proposition of blockchain, there is no lack of trusted enough intermediaries in the financial/accounting sector.

Has this individual ever tried integrating a payment system into an online business? Payments on the internet are rife with inefficiencies and problems. The lack of electronic cash is a serious impediment to frictionless commerce.

Without cryptocurrency, the road ahead seems to fork between a future with a hodge podge of non-compatible processors, or one with a single payment processor holding a virtual monopoly over the market.

>>Very few people outside so-called crypto-anarchist community are opposed to trusted intermediaries as a matter of principle, and outside this (admittedly vocal) minority and those who for their own personal reasons want to believe in this scheme

It's not just "crypto-anarchists" who care about removing trusted intermediaries. Anyone who doesn't want
to be a captive consumer of a trusted third party that runs a platform they are locked into by virtue of its network effect, will be interested in immutable protocols replacing platforms run by trusted intermediaries.

>>also by certified wingnuts from the long-discredited hyper-libertarian Austrian school of economics,

Ad hominem nonsense like this really discredits the article.

>>the bog standard public blockchain with its Proof of Work scheme (e.g. how Bitcoin burns electricity) is certainly not going to cut transaction costs enough, as throughput rates are simply not even within two orders of magnitude from what is needed. Case in point: a Bitcoin developer conference just announced it won’t be accepting Bitcoin as a means of payment, because it’s too slow and the transaction fees are too high.

As a self-avowed blockchain researcher, it's odd that he's not aware of Bitcoin Cash, and is using Bitcoin Core's self-imposed 1 MB per 10 minute throughput cap as the technical limits of what Proof of Work could scale to.

The article is a disingenuous hit piece.

It is condescending. Asking people to do FizzBuzz indicates that you expect a large portion of your candidates to be completely clueless. That's not a good message to send.

Think about the following. FizzBuzz filters out some extreme cases of incompetence, but tells you nothing of value about the people who passed. You can use the same chunk of interview time to ask a more challenging question that will still filter out the extremely incompetent, but also give you some level of confidence in the people who passed. So why would you prefer to ask a question that gives you less useful information?

It's not unlike a sorted array search algorithm. To maximize your efficiency you start in the middle, not at some arbitrarily chosen low point.

I'm guessing you are pulling less than 80 lbs. Probably closer to 40. The article mentions that 20 a minute wouldn't be an issue at this weight but the longbows in question where over 100 lbs and often 150 lbs pull. This is what they are saying is impossible to sustain at a rate of 10-12 per minute. You might be good the first minute but would drop off quickly after that.

For those not used to the sport, most untrained adult men have issues pulling back 70 lbs more than once. With a little practice this becomes "easy" but there is definitely and learning and strength curve.
