Wow this is really well done. It's like a visual-algebraic approach... I've never seen this before.

I like how the author sets up a "grammar of matrix multiplications," and then reuses the same patterns in the rest of the document.

What you're missing is that since the Comprehensive Test Ban Treaty came into effect it's illegal to test-detonate nuclear weapons. Which are narrowly defined in terms of fission devices, with or without a fusion booster.

Fission devices have been very well understood since the early 1950s, but fusion reactions are somewhat less so. The NIF provides an instrument for probing the plasma densities and temperatures that occur inside a nuclear fireball, so is directly relevant to H-bomb research.

This becomes trivially obvious when you realize that a laser implosion fusion reactor producing power would need to achieve in excess of ten ignitions per second to produce the sort of power output needed just to power its own lasers ... and that each hohlraum costs on the order of a third of a million dollars. (What kind of power plant costs $11Bn per hour to operate?) Answer: it's not a remotely practical design for generating electricity, so it must be something else, and promoting it as "clean energy from fusion power" is a cynical propaganda move to disguise a nuclear weapons research tool.

The final clue is that the NIF is operated by Lawrence Livermore National Laboratory, whose primary job is designing and ensuring the reliability of nuclear weapons.
A single pellet contains a lot of atoms. The current process is able to fuse some of those but soon the plasma cools down.

The goal is to start fusion by compressing the pellet using lasers and then use magnets to keep the plasma (charged, very hot gas/thing) confined to a small volume and hot enough so fusion becomes a chain reaction until all atoms of the pellet becomes a heavier element, when fusion stops (because a much higher temperature and pressure is required to fuse those).

This will generate a lot of energy which you car harness capturing the heat (by stoping the neutrons it emits or other method).

Use that heat to vaporize water to very high temperatures and use the high pressure to squeeze it through a pipe and then to push a generator.

So, this is a pulse thing. Pellet, laser, fusion, discard. Repeat.
Sure, I agree.

The issue is the word "computer" means not "device we have made" but "universal turing machine".

Ie., a computer is any system which realises a function from the Naturals to the Naturals.

Physics barely, if at all, has any use whatsoever for those functions. It is a very important point.

Computer scientists (ie., discrete mathematicians) are not the people who are even able to describe, engineer and build whatever is needed for an AI -- if, as I claim, continuous dynamical properties are needed.

(As, for example, they are needed by pretty much every system.)

No, not really. Epik can probably continue with their business relatively unscathed.

This isn't going to straight up eviscerate the company like some ransomware attacks we've seen recently.

In this case the hackers were either lazy or incompetent, they could've defaced every single Epik customer domain and made it very difficult for Epik to restore the DNS configurations. For some reason they didn't do that ¯\_(ツ)_/¯

Use of fusion as an energy source removes a lot of threats our civilizations are facing but it also comes with some caveats rooted in human behavior.

Human energy consumption has always gone up when the supply got more efficient, from coal to oil to fission. While here, the power generation itself won't have such a drastic impact (unless humanity overdoes it, though, we seem to always do that) but maybe more power means more consumption and demand for other goods that get used up while using things that consume power. And with enough power you can think about making things that consume more or even build more things that consume more power. Lots of processes that were considered too wasteful suddenly become feasible.

Just like with digital documents, when people predicted that paper wouldn't be needed in the modern economy and the demand for paper would decline, it has actually skyrocketed - because a paper document isn't important anymore. You throw it away and print a new one when it has a crease.

Historically, we've been very bad at predicting such side effects. So I won't buy in a 'fusion solves everything' mindset. Fusion power can be a boon for humanity on a global scale but it could also make some problems worse.

I would say it is not about writing style but more about the personality of the author. According to MBTI for example, people are either Thinking (T) or Feeling (F), and I would imagine that strongly Feeling people focus much more on emotions (as compared to Thinking people) when expressing anything - be it talking, writing, etc. To them, the expression of emotion towards a particular subject is as important, if not more, than the objective value / knowledge / information imparted.

I can also hazard a guess that there are more Thinking people lurking in HN vs Feeling people, thus the general repulsion towards that style of writing.
I always thought this was the normal size for churches until I left home (I grew up by St Albans Cathedral, also known as the Abbey amongst locals as the church previously had a monastery.

It's effectively measuring emotional response to fictional events, which sounds like a plausible way to diagnose a huge range of mental disorders. But if the subject wants to be diagnosed, why not just ask them how something made them feel? And if they don't want to be diagnosed (like you would expect for some sociopaths, pedophiles etc.) this won't help. If a full polygraph can't be proven to work against unwilling suspects, then one fourth of a polygraph won't work either.
Given the current trends, it seems very unlikely that fusion will be even close to competitive with solar or wind by the time it arrives (which is still probably more than 20 years away as a commercial endeavor).

Fusion, in any of its forms, requires some of the highest technology ever produced by mankind. It then exposes these ultra-high-tech wonders to extreme temperatures, and extreme temperature differences, and large amounts of extreme radiation (neutron bombardment), plus corrosion from the extremely fine hydrogen gas. Initial fusion power plants will operate at a very small energy efficiency, and they will need constant maintenance via high-tech robots capable of withstanding the radioactive environment that the neutron bombardment will create all around the reactor. Most pieces of the reactor will probably not last for more than a few months or at best years, due to all of the pressures described before.

Not to mention, the potential for catastrophic failure, though much less than with fission, is still enough to completely destroy the reactor and a good chunk of the plant, if the plasma containment fails. While of course incomparably safer than a fission reactor meltdown, it would still be a massive economic issue.

So commercial fusion, when it does finally arrive (or if), will be extremely expensive, with its only plausible use case as a somewhat reliable base load. Cheap fusion, if it is even possible, is much further away into the future than that - I would confidently bet that cheap fusion will not exist this century, even if ITER or others reach all of their milestones as planned.

Rationality was hip at the end of the 19th century when the intelligentsia believed religious dogmatism was the root of all evil. Rationalism was the logical counter-draft.

The early 20th century proved that humans can also commit atrocities and form dogmata without religion.

Later thoughts relativized rationality, which was a necessary step in my opinion.

We rarely see rationality today even if many try to claim it for themselves.

I think bigger house and nicer holidays are mere examples of what to do with more money. There is no point in comparing them in particular with the effects of working inanities team. The good thing about money is that it buys you freedom to do whatever you think is worth.

For example, I know people that look for higher paying jobs so they can work 2 years and not work 1 year. So the “spending 8 hours a day with a team” calculation is very different. You are looking for a higher paying job precisely to not need to spend 8 hours with people working. Which kind of applies to everyone when you give the option to retire earlier and have good money to take care of themselves and their family when old. You are earning ore to work less.

Lastly, you seem to apply a correlation between higher paying jobs and not liking people I your team. In my opinion, there is zero correlation. So leaving a job for a higher pay doesn’t mean at all that you will find a team that you enjoy less working with. The chance of actually enjoying more is just the same.

If you happen to find yourself in a team that makes you unhappy, but all means, leave immediately. But not changing jobs to a earn more because tou are afraid it will be a team that you will enjoy less working is the wrong thing to do.

I think looking for a higher pay (be it by negotiating promotions in the same company or by changing jobs) is almost always the right choice. And I do not mean in the “greedy” sense, I mean that is a very effective way to achieve more happiness.

But yes I could see a few good reasons for setting up one of these, if for just a learning experiment.
Event sourcing (and CQRS in general) is often compared (as comments here are doing) to "simple" CRUD and why add the complexity.

The difference is that event sourcing, aggregates and CQRS force you to actually identify the entities and the external and internal events that cause them to change.

It forces you to do the analysis that you should do anyway, but is often lost or forgotten when it devolves to "simple" CRUD. You end up adding change logging, histories, materialized view updating etc etc, all of which come "for free" if you do the work to establish what you're trying to build.

WALs are not the same as a business level entity/event stream, WALs are event streams for the database, not the business logic you're using the database for.

Yes, it is more complex, but, in combination with techniques like domain driven design and creating ubiquitous languages, your business logic will end up actually being simpler and closer to reality.

I was part of a team that the developed a workflow management system for managing telecom's infrastructure. We were really quite proud of it, it pushed our boundaries during development and we learned a lot of new skills. It was implemented exactly as per the clients spec.

It was also quite expensive, my employer billed them €300,000 for the work.

They accepted it.... and then didn't use it.

There was some use in the first few weeks, but then it petered off - despite this they kept paying us to manage the hosting and suuport of the system.

After a few months our manager approached them to ask if everything was Okay. Their response was to say the thought it was an amazing system, but now they realised it was way over-specced and using it was more of a burden than they expected it to be.

I suppose it was the software development equivalent of ordering the biggest thing on the menu and then regretting it.

If you host with Azure or Epik you were exposed to serious security vulnerabilities in the last 3 months.

You can't claim Epik is an "insecure location" while Azure is not while Azure has the absolute worst kind of security vulnerabilities. I'll remind you that Microsoft spends multiple billions of dollars on security and has large security and incident response teams :)

I think it's pretty unlikely you'll be able to learn the UK rules to a human level using brute force ML - take a fairly easy clue like ‘Drunken men are more despicable' - you need to split this as (wordplay = drunken (anagram of) "men are") / (meaning = "more despicable") = "MEANER"

This is really hard for supervised learning - the reward is quite sparse (e.g. did you get it right / how many characters did you get right) but the task is reasonably complex (e.g. it would have to learn how to spot/execute arbitrary length anagrams on its own, already something that is nontrivial for ML). Sparse + complex usually means gradient descent will fail or converge to a more trivial minima e.g. only look for synonyms in the clue.

I reckon you would have to codify the different types of cryptic clues manually for this work well.
I want to say that I have friends who are against installing a video surveillance camera in the house because, lol, they are afraid that they will look ridiculous later on the record.

- Link detection in comments with hotkeys to open them directly

- Better readbility and formatting of comments

- Hotkeys for the most common actions

> fusion power as it gets closer to success and eventual general availability

IMO it is not clear that fusion will ever be useable for power plants: Depending on costs (construction/maintenance/decomissioning), it might never be competitive with (battery backed) photovoltaics (or wind), no matter how much progress we make.

Personally I believe that fusion research is worthwile no matter the outcome, but calling it a "purely academic waste of ressources without positive environmental/economical ROI" might turn out to be correct (playing devils advocate here but this is important to consider, no matter how much pro-nuclear you are).
Yup a few fields gets you a long way, though I would recommend an audit log updated by triggers, rather than audit fields.

For example on my CRUD rails app, we use audit triggers in combination with setting a postgres local config variable with the username, the audit triggers pull the user info from the variables and record them into the DB. With a little more work I could probably also pull a backtrace of what line of code caused the trigger. Best part is because its all in the DB, if we rollback a transaction, the audit entries dont commit either.

Because this stuff gets set in the application controller as an around filter it's all completely transparent to the devs. They just make ActiveRecord calls and the database records the queries, user, etc that made the change as well as storing all the changed fields into the audit log. Even if it's one of those update all commands.
