To get a real handle on this you need to look at metastability in electronic circuits. Essentially any asynchronous circuit with feedback even one as simple as a flip flop can fall into a stuck state such that it may never converge to a valid state (i.e. 1 or 0). The fix in electronics is to clock everything such that the setup and hold times are satisfied. The price for the clocking is a reduction in speed. In more general distributed systems, the fixes are going to be analogous. You'll need some mechanism for admission control and you may need it internally and externally. The article discusses not meeting the response time budget for the web page or app. With admission control you can tell if you're not going to meet that budget and implement a circuit breaker, rate limit and/or polling mechanism on the clients. That increases the complexity of the system but provides increased reliability. Building glitchy systems or circuits is an engineering failure.

See here for the discussion of metastable circuits.

Rob Pike’s 5 rules:

https://users.ece.utexas.edu/~adnan/pike.html

Rule 5. Data dominates. If you've chosen the right data structures and organized things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.
It was before my time.

I know the Commodore 64 was somewhat popular. There were other computers with games but I don’t think any of them had the capabilities the C-64 did (Apple-II, TRS-80). The ZX was released under the Timex brand but like the Atari I’m not sure it ever went anywhere.

From the history I’ve read I think part of it may be that Atari was just kind of a disaster here. The fact that Atari actually had popularity in Europe plus they could probably make their own decisions without interference from Atari US may have been what allowed them to succeed in Europe. But that’s a guess.
Not saying you shouldn't go for space tech, but I know lots of people and some European tech companies who went into space tech. They all had pretty much same kind of experiences:

- Lots of regulations (for launching rockets, operating ground stations etc.)

- Everything is REALLY slow

- Very high risk (your 500k mini satellite may blow up with the rocket during launch)

- Things are very expensive and there are lots of (small and large) hidden/unknown fees that you'll face during the projects
Absent further information, it's not clear that anything novel was revealed: it's likely this was already public information, and that the AG has merely lowered the bar to (automatically) accessing it.
I've had to work with some really complex data types and I have really appreciated the utility types, conditional types, modifying data type recursively, template literal types etc. I was wondering how many other types languages are able to do all that stuff.
In fact, these are the exactly the kind of people that the LC process is designed to filter for.

The light bulb was a great invention but what really changed the world was the lightbulb making machine.

Billions have been invested in engine and transmission design and manufacturing optimization. Engines are surprisingly cheap to make.

Emissions and efficiency requirements have made them more complex.

I wonder if the last hurrah will be an engine with fully electrically controlled valves, like Koenigsegg already has. Getting rid of all belts and chains could be great for reliability. All pumps would be electric.

The Australian government also put its citizens in concentration camps with total impunity last year. That sort of outrageous mistreatment of lower and middle class people is not feasible outside of a few cities in the United States. Cheran in Mexico is also a good example of how resisting state-mandated civilian disarmament can discourage the abuse of citizens by powerful organizations.
This is actually due to the camera having a difficulty distinguishing whether your hand belongs to you or not. One thing you can do if you still want a fake background is to get one of the white photo background sheets that professional photographers use and put it behind you. It makes it a lot easier for the camera to tell what’s you and what isn’t and also really helps to prevent the bleeding effect that happens around where your face meets the background.
Seeing an open source project's reviewer begin with "Why did you do it this way instead of X?" is the the most shocking shutdown I have seen this year.

> In type-driven development, types are tools for constructing programs. We treat the type as the plan for a program, and use the compiler and type checker as our assistant, guiding us to a complete program that satisfies the type. The more expressive the type is that we give up front, the more confidence we can have that the resulting program will be correct.

“Overall independent app developers’ average monthly revenue is $1,500, medium-size company developers make $7,500 a month and large studios developers teams generate on average $44,000 monthly.”

I'm quite aware of the BP rewrite problem.

I should explain that what I had in mind is that nearly worn out blocks should be marked no-longer-to-be-written-to. I left that part out due to writing too quickly. The point is there's no need to move blocks, just stop writing to worn-out blocks, and then the CoW nature of the filesystem will take care of the rest. Eventually you'll run out of non-worn-out blocks and the filesystem will become effectively read-only.

(Naturally one would want to keep a count of the number of worn-out blocks in the volume, and one would need an internal file in which to keep track of worn-out blocks, probably.)

As for BP rewrite, the fundamental design fault in ZFS that makes BP rewrite hard is that block pointers include locations in them and so the checksums of blocks that have block pointers must change when any of those pointer-to blocks are relocated. What should have happened instead is that physical locations should have been separated so as to avoid block checksums binding physical block addresses: a) block pointers should have had no physical location in them, b) every block that contain block pointers should have been followed immediately by a "cache" array of physical pointers corresponding to the logical block pointers in that block, c) the "cache" of physical block addresses would then be easily excluded from block checksum computations, d) block caches would have been easy to overwrite.

Once block checksums in block pointers do not bind physical addresses, you can then traverse the tree and relocate blocks by copying them to new locations then re-writing the physical block addresses in the caches (that are now not bound into those checksums). This is a very simple process. You do need to avoid creating multiple copies of blocks that are reachable via multiple paths (because of hardlinks).

This proposal tends to obtain replies to the effect of that design increasing the risk of checksum collisions. That's fallacious for cryptographic checksums.

I continue to be shocked that the BP rewrite problem isn't properly understood.

However, it is probably too late to fix ZFS to make BP rewrite easy. The reason is two-fold: 1) the lack of BP rewrite has been worked around for things like vdev evacuation, 2) moving physical locations out of the block pointer would essentially yield a completely different on-disk layout for znodes and indirect nodes and so on, and moving to the new on-disk format would result in special-casing a lot of code, and would be quite a process. It would almost be easier to start over.
History repeats itself a lot.

I believe some of the early PS2 games were programmed in a similar manner. Devs had trouble getting their head around the Emotion Engine so they used the piece of the hardware they understood well: the older processor.

And we know the same thing happened with the PS3. The SPUs were hard to use so many early games practically ignored them, the same way many Jaguar and Saturn games ignored the other processors as much as possible.
Best way into front end development for mid 30s career pivot?
I've worked as a musician and supplemented that with video production work for about a decade.

In March 2020 when the world shut down for COVID, I started learning web development. Taught myself modern HTML, CSS, Javascript, React, common JS libraries, SASS/SCSS. Built some portfolio. Hustled and did a bit of freelance work.

I am now attempting to find a job doing front end development, but I'll admit it's pretty discouraging to apply for an entry level job with 100+ other applicants and rarely hear back from the company or recruiter.

What would you suggest to someone like me trying to work their way in?

P.S. Currently learning more about MongoDB, node/express, and Typescript because a lot of jobs ask for experience here. Maybe this is the problem? Just not knowing enough tools?

> verifying the authenticity, integrity and/or the physical state of an item by employing the propagation behaviour of electromagnetic waves. In particular, it enables to check for any tamper attempts for larger structures, such as off-the-shelf computers and their periphery. The technology extends existing tamper proof approaches from the chip/PCB to a system level and is easily retrofittable.
In this presentation, we are demonstrating exemplary tamper proofing in order to protect secret information without an attack-detection or data-deletion circuit (!), which is a known difficult problem and an imperfect undertaking. Therefore, we demonstrate the simplicity and effectiveness using a very cheap self-made testbed (using alumium foil) to protect standard hardware against invasive attacks, such as needle probing through the case. Cyber-physical systems are ubiquitous and are often located in non-trustworthy environments, in which data is processed that is both sensitive and worth protecting.

This is often brought up, often by very vocal people on r/chicago, but I've lived in Chicago for years and have never missed nature. The lake is good enough for me. I suspect there are a ton of people like me. I grew up in a big city and I'm energized by the energy of big cities. I like green spaces, but I don't actually feel a compelling need to be in wilderness.
There is a very clear distinction between the two.

Assault rifles have automatic (or select-fire) capabilities. One trigger pull can produce many bullets.

Semi-automatic rifles, which were later called "assault weapons," can only produce one bullet per trigger pull. What makes them semi-automatic is that they automatically reload after firing. Many other types of guns also do this (eg double-action revolvers) and many take minimal movement to reload (eg lever-action and bolt-action rifles).

This is a very big difference. A commercial semiautomatic rifle is only slightly more lethal than a bolt-action rifle. An assault rifle is much more lethal than both.

> And pretty quickly, the highest tier is saturated and lower tier housing is built.

That’s definitely not what happens. Highest tier is saturated, developers say that “the market only wants highest tier housing”, and so more of the same gets built.

> Or higher tier housing is overbuilt and drives down costs of all tiers.

The opposite is what’s happening - the highest tier gets more and more expensive, and the lowest tier goes up too.

Many, many people will max out the house they can afford and pile 2 car loans on top of that. That right there can be 40-50% pre tax income.

We now have a public with only a fuzzy memory of what a real recession looks like. Thanks to the accommodative Fed over the last ~14 years and more recent COVID free money bonanza, people have been rewarded for blindly taking risk and conditioned to think that prices always go up.

A severe contraction with a jump in unemployment and no Fed bailout seems quite possible and might be a painful lesson for the overextended.
This develops an immobilization in which the best choice is suspiciously-often found in accepting whatever comes; it's the prophet's conceit, a non-executive position which seeks to intuit outcomes rather than take risk and develop a smart path forward.

In application this psychology is not suitable for the full scope of political decisionmaking.

One needs to design a subjective logical system in which the leverage operates. The leverage could be used in thousands of different ways.

It relates, brcause everyone piles on the bandwagon to stay away from GAI, but doesn't articulate the fact that Artificisl Intelligence's utility as a tool stops the moment we have to recognize a sentient entity being behind the black box, with all the perverse incentives around setting the definition of "sentience" that entails.

If you can't see someone aggressively lobbying to have sentience defined in regulations just so in the forseeable future to get out of having to pay or recognize the self-sovereignty of a colloquially sentient AI... I got news for ya.

Mortgage and student loans play a part. A lot of it comes down to lifestyle choices and discretionary spending, essentially they are either bad at budgeting or sticking to it.

I've been thinking about this and IMO really it is more about the focus on regret as a motivator for action. Regret is a negative emotion, so this is basically a strategy of pain avoidance.

Where exactly is the "doxxing"? This data appears to have come from individuals who willingly filled out government forms in a state with a FOIA-style law (the PRA) that includes all government information not explicitly excluded.

This is consistent with how FOIA and CCW laws interact in most states. For example, here's NY's explanation of how SAFE and FOIL interact[1].

My favorite underutilized approach to debugging is a hybrid of printf/trace debugging and using an interactive debugger. It's great to be able to tap into a running program and just dump variables at a location to a file.

For things that are called a lot and very threaded it's great to not have to lock up the program setting and resuming breakpoints, but the flexibility to be able to introduce new logging as you investigate instead of whatever you thought to log is great.

Especially because these sorts of predictions have happened before. Look at this prediction for the world in 2022 from 1922:

>Vive la France?

> No one would be left to appreciate the Eiffel Tower or the Arc de Triomphe.

> French scientists were concerned about the nation’s birth rate 100 year ago. In 1860, there had been 1 million births in the country. In 1922, the number had fallen to 450,000.

> As one observer noted: “At the rate of decline in number of children born in that country, in the year 2022 — 100 years hence — there will be nobody left in France, except as they drift in from other sections of Europe. The figures show, unerringly, that the present rate of decrease, maintained for 100 years, would reduce the birthrate to zero.”

And what happened in the 20th century post WW2? A French Baby Boom driven by increased marital fertility: https://en.wikipedia.org/wiki/Mid-20th_century_baby_boom#Eur...

> France and Austria experienced the strongest baby booms in Europe.[19] In contrast to most other countries, the French and Austrian baby booms were driven primarily by an increase in marital fertility.[28] In the French case, pronatalist policies were an important factor in this increase.[29] Weaker baby booms occurred in Germany, Switzerland, Belgium and the Netherlands.[30]

We really have no idea what is going on with fertility and what the end result will be. When population was booming everyone predicted mass starvation that didn't happen. Now when population is declining everyone is confidently predicting disaster, but who's to say it won't self-correct? (alongside appropriate societal efforts)?
