Whether intentionally or not the article entrenches some narrow ideas of what blockchain is. At this point talking about Bitcoin as _the_ blockchain is an ancient narrative and does not see wood for the trees. Bitcoin fulfills a certain goal but the world of blockchain (and related to them) systems has become extremely diverse, with many systems racing to fill many niches in various ways. We should drop the Bitcoin == blockchain narrative. It's a narrative for non-technical people and maximalists. We should even stop using the word "cryptocurrency".

Let's take Baseline project as an example of one that defies our ideas of what blockchain is meant to do. Baseline is a protocol developed by a few parties, in particular EY and Microsoft, that means to reduce friction in _communication_ between business entities. If, say, a factory needs more parts delivered it's SAP system communicates with the supplier's Oracle system through a public mainnet protocol encrypted via Zero-Knowledge Proofs. Yes, the system could potentially also handle transfer of value, but it's more than that. It's not bitcoin, it's not a currency, transfer of values isn't even the main point, it's a system of record and communication.
This is definitely my guess. People don't sleep as well when they're anxious even if they're in bed the usual amount of time.
How does it know whether certain IPs are static? It labels XS4ALL's residential range correctly as static but surely the owners of this site didn't investigate a random Dutch ISP to find out whether they rotate IP addresses. Is there s registry for this sort of thing? It's not in the whois info that I can see.

I know people who feel more burned out at a job with no deadlines and very little work to do. Some people burn out because they feel their work is meaningless, and so in a way their life in meaningless. Add to that the feeling that they are still subjugated to their boss's whims, so they are not in total control over lives. I think finding a company with a culture/purpose/product that fits your personality is definitely worth the effort in that it can alleviate those issues.
These questions often ignore the investment (both in time and money) people have made in a particular platform. Even if you assume each platform is equivalent (which isn't true), there's still switching costs incurred moving from one to the other. For many people those switching costs will outweigh any costs incurred from the chip transition.

The next release of our PerfectTablePlan seating software (https://www.perfecttableplan.com) will have a social distancing feature. This will allow you to check social distancing at seated events (such as wedding receiptions and galas). It wasn't too difficult to add as we know the x,y position of each seat and the group each occupant belongs to.
> A digital currency that requires a sophisticated global computer network to function.

That's stretching it a bit. While Bitcoin looks sophisticated to the average Joe, it is actually a very simple protocol and require very little bandwidth. It's possible to run mining operations from all over the world on very limited connection (in fact you might need to connect only a few times per day). Processing transactions also consume very little bandwidth.

The crypto-folks have come up with something for you: https://blockstream.com/satellite/

So now even if your local infrastructure burned, you can still transact in bitcoin. Granted, there should be some guys somewhere doing the mining to ensure that the network is secure enough.

I think you are massively incorrect. Equities right now are at a pretty massive discount to future value. If anything I think the coronavirus effect on the economy has just demonstrated that economic growth is fundamentally not impacted much by around 1/3 of all jobs. The labor product and consumption activity of that 33.3% just doesn’t matter.

The implications of this seem mostly sociological to me. Is that a good state of affairs for the world? Could we use those people more productively?

The implications are not about the current stock market.

Amazon and Microsoft are pretty damn likely to keep growing in value for 10+ more years regardless of any coronavirus situation. That’s an amazing / dumbfounding situation. But it still would imply a rational longterm investors sees those stocks as being attractively priced right now.
If you expect to continue to scale, the multi-tenancy should be in software.

One reason is overhead. Each instance of the system will have overhead, and as you scale to more and more customers, that overhead will eat up your profits. If it's a well-engineered multi-tenant system, you won't have this issue.
It takes a lot of patience but it is oh so rewarding. I like to think of it as "software archaeology".

It's fun to gradually discover the model that the programmer was intending to program, then to see where it broke down X months/years later and was fixed with a hack. Then, you get to design a new model that fits both cases elegantly, instead of just a subset.

You kind of feel like the scientists in Jurassic Park! :)
Thanks a bunch!

I think the biggest issues with this approach is the requirement for embeddings. It's hard sometimes for a customer to understand what layer to pull out of their net to send to us, so sometimes we just use a pretrained net to generate embeddings. One net for audio, one net for imagery, one net for pointclouds, etc.

I'd say that it's harder for this tool to work with structured/tabular data for a few reasons.

One, most structured datasets are domain-specific, so it's not easy to pull a pretrained model off the shelf to generate embeddings - typically we would need a customer to give us the embeddings from their own model in these cases.

Two, neural nets actually aren't the best for certain structured data tasks. Tree-based techniques often get better performance on simpler tasks, which means there's no obvious embedding to pull from the model.

Three, an alternate interpretation is that a feature vector input for structured data tasks is already an embedding! When the input data is low dimensional, you can do anomaly detection and clustering just by histogramming and other basic population statistics on your data, so it's a lot easier than dealing with unstructured data like imagery.

So I wouldn't say that our tooling wouldn't work for structured data, but more that in those types of cases, maybe there's something simpler that works just as well.
Scrum is a framework prone to gaming simply because what gets recorded and measured is what gets used to evaluate someone and Scrum records and measures primarily tasks.

I wrote an answer on Stack Exchange about this (see link below), but Scrum tends to make everything about Scrum itself and all other actions begin to serve the sprint and not the project. When that happens, it becomes more important to look good according to Scrum than to actually get anything done (especially when the product owner/Scrum master are non-technical).

I know that in my job, people often judge me on the task board alone. It would not surprise me if something similar is happening in your company.

If you read some of the other answers to that question, there are numerous stories of developers using Scrum as a way to slack off.

I don't know what you can do about him as I suspect he is acting rather rationally. The fact that he can get away with this seems to indicate that overall productivity and work product do not really matter.
I’ve felt exhausted for the past month. I also started full-time remote work in December. My previous routine of working out at the gym before work vanished.

I don’t know how much of this is anxiety and how much is new bad habits (or lack of good habits). Some of it is stress (my new job is stressful). Some of it is the constant fireworks, instability, and the rise in violence in my area since the protests started.

But I definitely relate to feeling tired now.

Something I don't see a lot of people talking about with Tesla is that over the last couple years, the writing has appeared on the wall about internal-combustion.

Wild.

I guess with custom protocols there’s not much that can be learned from that setup. Presumably wrap the request in security, handshake to verify authority, use the custom protocol to deliver the secret which is also wrapped in security.

Too bad they keep it close to the vest, but I certainly don’t begrudge them for it.

Great article! The above comment has it all wrong.

Article date is june 30, stock price was .008 on june 30. On July 6th CLWD hit .0162 high.

Some of these things do not quite work this way, but they demonstrate some interesting peculiarities! The eval should be expr, as you are trying to evaluate a mathematical expression, not a command. Similar to the common footgun:

set a 1
puts [expr $a + $a] # Wrong!
puts [expr {$a + $a}] # Correct

Also $$b expands to $a, not 5, as dollar expansion stops at the next non-alphanumeric-or-underscore character. This would usually be written as [set $b] (equivalent to [set [set b]] ), utilising that the set command outputs the value of the variable with that name. Similarly, [set var[set $b]] for the last line. Also, # is only a special character at the beginning of a statement, so comments have to follow a newline or semicolon.

In the “everything is a string” department, my favourite are block comments:

if 0 {
This is a comment.
}

You can write any kind of comment in there, even special characters like $undefined or [undefined] which would cause errors in normal code. Only wrongly matched {} would be a problem.

> Downclocking because of overheating and insane waitcycles to get out of this mess which is AVX512, plus poor HW support (only on insecure Intel CPU's which need to be probed at runtime) makes it an esoteric extension. AVX256 is good enough for most purposes and is not that insane.

> Lack of adoption of AVX-512 would be Intel's own issue. If they wanted it to succeed, they would try to put it on more chips than just the few lines you mentioned. As it currently stands, Intel is setting up AVX-512 to fail by only putting it in so few products.

It will be fun to revisit these sorts of comments next year when AMD releases Zen4 based processors that support it. Like with raytracing, I suspect people's tune will change when the red man does it instead of the blue man or green man ;)

(it may even be in Zen3, that "50% improved FP performance" sure is interesting if you figure that's about what you would get from ideal-case speedups of AVX-512... I suspect they are moving to dual 256b units and at that point you might as well make them gangable into a 512b unit. If they don't go there with Zen3 it is an obvious low-hanging fruit for Zen4.)
Maybe there is a case to be made here, and maybe you can make a convincing one given more time. However, as it stands there's a world of difference between the rise to (local) power of someone like Kejriwal and the claim that India is more democratic than the US. That is a rather specific feature that, even if true, is neither sufficient nor required to be democratic.
We haven't even rolled back the quantitive easing from the last recession. These financial rescues are now becoming permanent fixtures on our balance sheets. At least with health care, we would have something to show for these massive injections of money. Instead we just get inflated asset prices and growing wealth inequality.

I can vote for local taxes - either directly via ballot propositions in California or indirectly by electing the people who will decide these taxes. Can I vote for the mafia here?

There is a predictability with taxes - I know exactly how much I am going to pay, how and when the tax rate is going to change etc. Any change comes with sufficient notice and always subject to a democratic process which I can participate in (town halls, petitions to governments, elections). What is the predictability / process here?

Taxes are still constrained to the constitutional framework of the USA. And there is a clearly defined legislative process which people can follow in case they think taxes are unjust. Judicial rulings are enforced throughout the country. What is the process here to address my grievances? Is it predictable or subject to whims of the local mafia?
I think these are excellent things to keep in mind, but the vast majority of real life is not D-Day or crash landing in the Hudson. I'd go so far as to say that most people hardly ever even spend any time solving "dynamic complex problems." People being really, really good at stuff is important, but I don't think it follows that everyone should only do one thing.

I have a hunch that Eisenhower himself was probably a person who could do most of the things on that list.
Enterprise indeed, including charging premium for features that should come by default.

Guilty

IMO it comes down to good habits and (more importantly) kids. I have never been more relaxed in my life. I get 8+ hours of sleep every night, and sometimes nap during the day. Cutting down on long commutes has made such a positive difference to my life that I'm never doing it again, pandemic or not.

Everyone I know with young children is on the opposite end of the spectrum though, now that childcare/daycare/babysitting/family assistance options aren't available anymore.
I’m going to see a sleep doctor on Friday. I’ve been napping two hours every day from 12-2 like clockwork and I wake up feeling confused and more tired than when I went to sleep. I did a sleep study years ago and was diagnosed with OSA but always felt like I was suffocating wearing the CPAP. Tried in the last few weeks to just force myself to wear the thing and I feel like I’m stopping breathing as I fall asleep. It’s awful and a damned if I do damned if I don’t kind of thing. Hopefully it’s “just” apnea because I feel like I’m literally going crazy from such poor sleep.
You've kind of tainted the answers you might get by leaving in the assertion that those that say they are out to make the world a better place are secretly wanting to make more money, but I'll bite.

I did my stint in a couple fintech and yes, I consider the industry evil. Not Machiavelli evil, or Saturday morning cartoon evil; but evil in the absolute banality sense.

They're out to make more money. Alright, how?

The answers vary, but invariably boil down to:

A) Make previously impractical value extractive transaction practical through automation augmented with ubiquitous connectivity. This is a winning business plan, but doesn't really make the world a better place for everyone. It just makes yet another financial extraction mechanism.

B) Make or exploit arbitrage possibilities through exploitation of information asymmetry to extract value. May be good for liquidity, but these micro-extractions of value don't tend toward creating a macroscale change, but nevertheless, more "value" is created. This suggests to me an artifact generated by fundamental constraints of the model rather than actual problems being solved.

C) Make something marginally "cheaper", but extract a small slice, multiply by economy of scale. This model maintains status quo, and never really pays off for the end user until someone really puts competitive pressure on another actor, yet with consolidation happy markets that competitor never tends to stick around long enough.

D) Loss lead, but monetize data. Should be self evident.

Making money just to make money is not in and of itself a virtuous goal for the world in general given money's fundamental purpose of being a promissory note on the improvement or capacity to follow through on a promise. If all you're spending time doing is making more I.O.U.s, your problem solving is never actually meeting the road and propelling society down the road of not having to worry about things they previously had to. This manifests in pattern where making more money in the face of climate change for instance, blooms like a good idea because you're making more money right now, but you're ending your fiscal yardsticking there. Feel free to replace "climate change" with any long cycle problem that can be exacerbated by putting it off til later in order to optimize on some more achievable and tangible metric now.

That's my two cents. It's the most boring kind of evil. The kind you can't really build up the motivation to fix, and even worse, bewitching in that even when you're pretty sure you've discovered that "neat trick", once you see it out to the end you realize you just did the same thing everyone else did, and didn't realize it.

> With closures you often end up with circular references.

In that case, you can manually lift the data object involved into a function argument, as opposed to a variable capture - with its ownership being thus managed explicitly. This is generally an improvement in design.

Of course, Rust does only solve memory management problems "to a point"; there are cases where fully general GC is pretty much a necessity. But even most uses of closures - a fairly high-level language feature, all things considered - don't require this in many cases.

I based that belief not on the article but the fact that Signal threw up a modal dialog the other day and forced me to add a PIN which I had been postponing doing due to misgivings about the SGX thing.

The word "some" is doing an interesting amount of work in your comment, incidentally, since every other mainstream messenger just stores this stuff in something like a serverside SQL database.

It's only doing the work of disagreeing with your blanket assertion. I'm not now and nor have I ever gone about telling people they need to get off Signal and use [something else], so it's unclear to me why you'd read that into my comment.
When you open a .torrent file or magnet link the client connects to a set of trackers (or DHT, a distributed tracker network) and receives a list of peers to connect to. This site just repeats that process for a bunch of different torrents and collates the resulting data. Of course, dynamic IP addresses are a thing—and the trackers can (and do) lie about which IP addresses are part of a swarm. If you see something that you didn't actually download it could be because your IP address was shared with another customer recently or it could simply be a tracker "poisoning the well" by mixing in random IPs.
