Wonder if Covid, in terms of deaths, ends up being seen as a significant moment in history as it moved the needle on different kinds of vaccines/treatments and they, in turn, saved more lives than Covid could claim...

Unfortunately not, I guess I could measure that using log analytics. Perhaps I'll do another right up on the impact of getting to the #1 of HN
Even with enough lead time, displacing as much mass as possible at just above escape velocity is the most efficient impulse transfer. For an asteroid of appreciable size, your tiny thrust would have to be not-so-tiny anyway. (Plus, chances are that a large mirror stimulating the Yarkovsky effect might be more efficient at this, and without the issues that a prolonged contact with a complex spacecraft might bring.)
My PhD was (partially) on this. The inability to inhibit actions when facts change on a short timescale (sub-second) is thought to be biological. According to the most widely accepted theory, think of the brain as having a slow system and a fast system. The slow system is good for complex processing, but of course it is slow. There is also a fast system for quickly responding to things. If something changes while the slow system is working, usually the fast system is pretty good at stopping the slow system from acting, allowing the brain time to incorporate the new information into its plans. But if you are already planning on doing something and getting ready to do it, there is a limit to how quickly the fast system can interrupt the slow system. It tends to be on the order of 1/10 to 1/5 of a second.

On a longer timescale (minutes to days), there is a clinical symptom called "perseveration" whereby people can't let go of previously held beliefs in the face of changing information. It is common in, e.g., patients with schizophrenia.
I think so far the ReBCO tape is manufactured in small quantities by a handful of suppliers. If there were million-dollar orders coming in regularly, I suppose there'd be a lot of competition to develop the highest quality product. I expect it'd be like batteries; there's a lot of incremental improvements, and then once in awhile a major chemistry change. There's probably other high-temperature superconductors just waiting to be invented.

If I remember right from one of the videos from the SPARC reactor folks, they were experimenting with not bothering with insulation between the magnet windings. The ReBCO film is bonded to a layer of stainless steel, and they figured the conductivity of the film is so much better than stainless steel that they wouldn't actually get much loss from current leaking through. That seems kind of crazy, but I guess there's a lot of things about superconducting materials that don't behave intuitively.

Maybe manufacturers can make film that's bonded to a thinner layer of stainless steel or whatever, and thus allow for more windings in the same space?
If anything this article shows why Financial companies aren't moving away from Mainframe. It is comparatively speaking such as small amount of money while the risk are incalculable. Upgrading to Z15 is a much easier option.
Wow! Great job! Readability is extremely important! By making it easier to see what the current major threats are will make us more focused and secure in the long run!
Thank you, this was refreshingly deep and technical for a retro article. Straight to assembly in part 1 is nice! :)

As someone growing up coding MC68k assembly, I think I was still not aware of the existance of the "vasm" cross-assembler. That might push me to clean up and make buildable a really old game I wrote, that would give some nice closure. :) Thanks!
The reactor can’t meltdown and contaminate the whole planet. Also there is no radioactive waste
On the monetisation point we do plan to have a paid version of the product too. We think that one of the limiting factors of using symbolic execution to date has been in the path explosion problem when analysing large programs. A large part of our reasoning behind building a new symbolic executor from scratch was that we wanted to be able to parallelise it to help overcome this issue. We intend to provide a cloud hosted version of Symbolica that makes use of this so that users can get access to this compute power on a pay per use basis.

So our rough plans at the moment are to charge on a consumption basis to use this service.
I think generics will change a lot of the ORM space for go yeah. Will be interesting to see.
Some interesting changes in the Top 10 this time around and in general, I think they're good changes.

It does suffer a little bit though from some of the entries being quite wide ranging and non-specific, which I think could leave people scratching their heads about exactly what's involved.

I'm glad to see that monitoring and logging is still included as, in many years as a web app pentester, it was really common to see no application level detection and response to security attacks.
You can certainly plan the detonation point.
even more censorship measures that results in more extreme speech and more harassment by making the targets of it unable to respond or to bring awareness, even worse, removing ability to become aware of such.

This is a terrible way to promote one way harassment.
Many people would like to adopt a newborn. Various laws and other barriers make it essentially impossible to adopt a newborn from another country.

https://adoptionnetwork.com/types-of-adoption-options/domest...

> Domestic – If you are looking to adopt a newborn or young infant, you are looking at a domestic adoption. It’s that simple.

> more babies that need adoption.

That's a strange way of looking at it. When you say it like that, it sounds as if a new baby will create an imbalance between supply and demand. There's 2 million families waiting to adopt a newborn, so a new baby will help balance that, not imbalance it.

Fertility is dropping, so I wonder if there will be an even higher demand for newborns in the future.

Elixir – Schemaless Changesets to separate Web context and the Business context
Mildly struggling with procrastination. I want to become a better developer who can contribute to Open Source projects but to be honest my inaction is likely the only thing in the way. This turns inward and I start disliking myself the more I think about my laziness.
Depends on what you mean by better.
As a society we have failed to really use fission. Fission does basically everything fusion promises to do.

Fission has a absurdly high energy density, the step from oil to fission is far more relevant then the step from fission to fusion.

Fusion would mean basically no fuel cost, but thorium is already a waste product and even uranium fuel is a tiny part of any fission plant.

Some people seem to believe the fusion is inherently prove against weapons, but this is equally not really true. If you had a working fission plant there would be ways to use it to get what you want to make a weapon.

There are some places you might want fusion, mainly in space travel but even there we are not anywhere even close to where we could get to with fission. Open gas nuclear thermal rockets anybody?

In sum, I'm not against this reseach but its not a way to solve our problems anytime soon. Fission you could get to run with 60s tech and amazing reactors could be designed within decades and often with comparatively small teams in the 60-80s and somehow we haven't managed to make it competitive.

Fusion looks to be far more complex to build in every possible way. How this will be cheaper is questionable to me.
>and for tax reasons it's very difficult for Mozilla Foundation to give money to Mozilla Corporation.

I'm aware but as far as I know it's the other way around.
The foundation extracts revenue from it's subsidiary the Mozilla Corporation. When in a state of decline and faced with the option of axing development that might hamper or reverse this decline i'd expect there to be an option for the foundation to reduce the amount of revenue it extracts.
Especially since what it actually gives away seems so little when compared (which makes me look weird at the mentioned compensation again)
I don't think this sounds 'bad'

For some random and arbitrary reason you and this existing employee didn't get on and are likely not to work well together.

This fact is obvious to them, to you and even HR - everyone is in agreement on this.

I wouldn't look as the rejection as just personal criticism of you - I'd see it as rejection of a team consisting of you and them. Unfortunately as they're the current employee and you're the applicant, you get the shitty end of this 'team rejection stick'.

I'd take the suggestion to "apply to other teams" as strong positive feedback and do just as they suggest. I'm sure Twitter has a long and illutrious applicant list, so if they didn't think you were a fit for the company they could have just told you (or not) and phoned the next person.
OP if you can pass that interview go work at a shit hot start up where you can contribute on a level these guys will never get to in Twitter.
Retail electricity prices in France are €0,13/kWh, so not that cheap (€0,18/kWh pre pandemic).

https://www.statista.com/statistics/418087/electricity-price...

This doesn't matter, though, because France doesn't need many nukes anymore, therefore doesn't subsidizes new plants anymore. One new plant is built in France, and it already is hellishly expensive: "As of 2020 the project is more than five times over budget and years behind schedule. Various safety problems have been raised, including weakness in the steel used in the reactor." https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...

Handing 99% of the money to contractors for what will in short order be thousands of tons of radioactive slag contributes minimally to actual research. The developers of the overwhelmingly more practical FRC reactor are left to get by on scraps. Elsewhere in science, money is, in fact, being "granted" directly to scientists. This has gone on since long before you were born.

All of the "scientific work on" ISS is done with crew literally pushing an "on" button on each bit of automated equipment running it. Experiments are forbidden to involve more interaction, and also forbidden to operate without that "on" button, so the crew has something, anything to do.

Commercial manned spaceflight could better have been worked without ISS. ISS's role was nothing more than a place to take them. Plus, a huge money sink on its own. It will soon fall out of the sky, and with any luck not hurt anybody where it crashes down.
Fun fact: the microwave door switch does not only switch the thing off, it also shorts the power line. If the switch contact were melted and fused together unable to disconnect, it pops the breaker.
I think the surprise comes from how long it takes to get the answer, not that it's incorrect.

By comparison, gcc is able to reduce those two implementations to the same thing and prove them equal in a fraction of the time (https://godbolt.org/z/6oMEd8ebY). If it takes Symbolica a minute for the same tiny example, how does it work on real codebases?

nano is interesting to watch. it is one of those DAGs/lattices, like stellar. they were vulnerable to spam and got written off after a couple exchange scams soured the early adopters and ddoses brought the network to a halt, but years later they’ve patched the place up and maybe it’ll work

The effective size comes from interfering signals taken simultaneously at widely separated receivers, so no, you cannot increase effective size in that way. What you gain from increasing exposure time is that you can see fainter objects.
Depends on your definition of "reasonable". You now can't leverage your DBA's skills to optimize queries, because you're using the RDBMS as a key/value store.

You're misusing a tool because you didn't do the correct application design in the first place.

NoSQL has it's place, mostly in the trash. Lazy key/value stores (which is all that NoSQL is) throw away all the benefits of relational logic for a glorified combination of a file system and grep.

That's not "delivering value to a customer", that's delivering crap.

Standard "Agile" response. It was only "far too late in the process" due to a complete lack of process, oversight, product quality ownership and capabilities.

If nothing else, that developer should be "counselled" as should the PO, the Scrum Master and anyone else involved that allowed the situation to occur.

And the ongoing capex and opex for the additional unbudgeted support should be pushed back on the PO as a requirement to fix.

It’s not true that hashish is made from high-CBD strains. That idea seems to be based on the common misunderstanding that indica strains have more CBD in them.

There are various types of hashish; the traditional Moroccan screened variety is almost certainly all cultivated indica, but Himalayan charas is almost certainly all landrace sativa.

I don't think this reduces down that far. That's part of it, but it's not all of it.

Even if this is true, why is it true? Why are these businesses getting so much less return per employee? Is the only solution to sacrifice wages? Is it worth sacrificing wages for everybody?

We can't just declare a thing presumably bad for smaller businesses and then say end of discussion, there's nothing else worth considering here.
If you need to run with anything more granular than INFO, then it's not ready for production.

And logs are not tracing or metrics or canaries or any of the other required operational monitoring capabilities that an application requires.
Back in the day I spent the best part of three years working with NMR machines pretty much on a daily basis, also never noticed any physical effects.

Once I almost had a magnet snatch my bunch of lab keys out of my hand, having forgotten the cardinal rule to "leave all magnetic materials at the desk before you approach the magnet with your sample tube"...

Heard a joke about the children of NMR staffers having atypical sex ratio, but that was just student humour. I think :)
There's plenty of DUI arrests where no drugs are present, the driver blows 0.00 on the breathalyzer, and the only "probable cause" for arrest is an officer's subjective "expert" opinion.

https://www.youtube.com/watch?v=gWyzPpYslYc

People have been arrested because the police claimed that a standard dose of Tylenol the night before was driving under the influence of drugs or alcohol. If a police officer wants to take you to jail you're going to jail.
Very questionable if a fusion reactor is safer then a common molten salt fission reactor. I would argue that is far less likely to 'explode'.

And you can burn up the waste majority of that waste, the leftover waste after that would not really a huge issue.

Both of these are far more political problems then actual real problems a society based on modern fission would have.
The fact this site has a fixed AdSense ad at the bottom of the page suggests they don't care that much about privacy.
New to the list is Server-Side Request Forgery (SSRF), where you trick the remote server to fetch a sensitive URL on an attackers behalf (eg, internal service or cloud metadata URL from the context of an internal server), a language-agnostic defense is using something like Stripe's Smokescreen [1] which acts as a SOCKS proxy your app connects to when requesting URLs that should be quarantine'd, and it does the enforcement of access to internal/external IPs or not.

Say hypothetically you want to pursue a certain area of CS and become proficient in it. I struggle when the PDFs run out, and I look to contribute to a Open Source project in the area however there seems to the chasm(obviously expected given I've only read an introduction on the topic effectively). It's bridging that chasm that I don't get. How do i go from writing Spark jobs to contributing to Spark?
Hey, the reason for the long times on the playground is actually that we’re having to wait for build servers to boot up and then build the code before we can finally ship it off to our backend for analysis. We’ve had quite a bit of feedback on this slowness and we hope to eliminate some of this constant factor boot up and compile time soon, and for what remains make it clear that this is what’s happening in the status box.

So although it might seem like it, we’re not actually doing any looping, we’re doing constraint solving as you’ve mentioned.
Ideally you could edit ALL of your incorrect comments. And put the correction on top.

So basically it sidesteps the type system issues in a similar way that an inconvenient car trip instead of taking a flight sidesteps the TSA issues? ;)
Sometimes the absence of features is itself a feature. SML is a much smaller language than OCaml and F#. Offhand, I can't recall anything it has that OCaml doesn't, although it does some things differently (e.g. structurally typed immutable records).

I'm not sure there is much reason to use SML itself today, given that it has stagnated since the late 90s, but it is an excellent language for teaching programming because you don't have to sweep anything under the rug. But if you want to use it, then it does actually have well-maintained pretty good compilers. MLton probably generates faster code than OCaml and F# in many cases. The main problem with SML is that there are not a lot of SML programmers around, and hence very few libraries, particularly for handling modern protocols and formats.
This shows that all e2e encryption efforts are totally worthless with regards to the company owning the service/app. Of course e2e encryption is very important and a good thing, but I never trusted all the "not even we can see your content unencrypted on our server" talk, as they could access anything in the app anyways if they wanted.

I brought this argument up many times in discussions but it was often deemed as being a conspiracy theory, but now here we have it.
XTDB (Crux) – Database for querying across time with bitemporal SQL and Datalog

Per battery or overall to the planet?

Per unit of storage, Wikipedia says the lifetime storage capacity of batteries etc. relative to energy needed to construct them is:

Lead acid: 5 times construction energy; Vanadium redox: 10; LiIon: 32; Pumped hydro: 704; Compressed air: 792.

I can’t remember where I’ve seen this, but I think a unit of PV produces all the energy it took to manufacture after a month or two.

If you mean overall? As a rough guide we emit about 35GT CO2/year which is about 9.5e12 kg carbon; burning carbon releases about 32MJ/kg; so about 3e20 J/year, or 9 TW, or 19 mW/m^2.

There’s more energy in the hydrogen in gases and oils, this is just a ballpark estimate of the thermodynamic output of burning that much does to directly heat the planet.

Did it have one X11 window per document, or just one for all documents?
It is. As far as I'm aware issues like these are only problematic if you either manually run a workflow (it uses your credentials) or have a workflow with the "pull_request_target" trigger (uses a token with write access). The latter has a plethora of potential pitfalls and should be avoided if you can.
