One of the greatest System Design stories of all time is the evolution of mammals.

Warm blood? A huge, complicated heart? Are you insane? The metabolism rates will be off the charts.

Record-breaking spin-up times before adulthood? Where the parent animals will have to actively care for their helpless young? And spend bodily resources to produce a fluid with which to constantly feed each one? How could they ever compete with a species that lays 10,000 eggs a year, dashing off after — or before — they hatch?

And yet, as They Might Be Giants put it, these disruptive designs, so seemingly flawed, made the difference between extinction in the cold and explosive, radiating growth.

P.S. Did you recognize the chicken-and-egg problem in the second paragraph?
If anyone had alleged "toxic paper is being stuffed into these CDOs and rated AAA by the ratings agencies even though they know it's garbage" while it was ongoing, it would have been dismissed as "conspiracy bs".

Part of the philosophy is to change the mindset from a “person” perspective to a “process” perspective. I.e., what gaps in the process led to the mishap, not what person caused the mishap.

Organizations that are people dependent rather than process dependent tend to have higher risks of failures.
Yeah I guess this is the life we have now. It is really strange. Now I understand why mankind want to achieve immortality. Life is too short, and distance is too far. There's no greater value in life than living in the moment with people you treasure.

This is a bad example: traffic is a complex sistem with a century of ruleset evolution specifically intended to isolate personal responsibility and provide a simple interface for the users, that, when correctly used, guarantees a collision free ride for all participants.

The systemic failures of trafic are more related to the fallible nature of its actors. The safety guarantees work only when humans demonstrate almost super-human regard to the safety of others, are never inattentive, tired, in a hurry or influenced by substances or medical conditions etc.

We try to align personal incentives to systemic goals with hefty punishments, but there is a diminishing return on that, at some point you have to consider humans unreliable and design your system to be fault-tolerant. Indeed, most modern trafic systems are doing this today with things like impact absorbing railings, speed bumps, wide shoulders and curves etc.
Yup, you are correct. However, the CPU still needs to figure that out by examining the read and write locations of all 3 instructions, which need to be decoded, then fused before execution.

I'm a dilettante in this area, but it doesn't sound trivial to me.
How do you enforce that other people provide provenance on text?

Taking the translation example - how do you enforce that users of Google Translate keep provenance in their translated text that remains with the text?
I wondered that as well - I suppose the added weight/complexity of using vanes that could be folded in (sort of like a big turbocharger) must not be worth any gains. Hard to beat the simplicity of a big tube.
The tool in question is (mainly) for scheduling meetings with third parties.
You can hack it if you get access to an older furnace being junked. You need the 24VAC transformer and the main relay (the really old furnaces don't have one of course). Then the smart thermostat (which probably needs the parasitic power from this) can run off that, and your millivolt system can run off the relay contact closure. That said, as always, keep your existing thermostat paralleled to it, just in case.
India is also focusing on RISC-V, as they do not have their own chip industry yet. Depending on the Western countries for your processors is something any country wants to de-risk.
I was looking at linear. But we do use kanban (no sprints). Do you know if sprints are basically a required part of using Linear?

Great project. Most games are too sedentary and making them physical has the potential to make a healthier genre of games. I’ve had some similar ideas that I never put to practice but the main idea was augment sports games with technology and bring them to the 21st century. Think about a basketball referee that keeps track of rules, bounds, etc or a mixture of augmented ball played with a phisical ball but which could interact with the background: eg projected shapes, sounds; etc

Look pretty exciting, debugging is the feature I'm always missing when working with Ghidra.

Will be intersting if ida also adds the debugger to there free version.
Let's entertain this idea...

Without a monopoly of violence, you have 3 alternatives:

a) Multiple entities keeping each other in check, in perpetual competition...

b) One faction becomes more powerful than the rest and eventually assimilates the rest or turn them into vassals.

c) Factions decide to ally up and either assimilate the rest and make vassals out of them.

Basically, smaller fish gets eaten by larger fish. The world is just like a large prison where you have to either become a large entity or belong to a large alliance otherwise you're fucked.
I think there are 2 problems:

1. Hydrogen is hard to contain and store cheaply; it's so light it escapes containers easily

2. Hydrogen is kind of explodey
An excerpt from "The Blue House" by Tomas Transtromer, which talks about this.

-----

The house is like a child’s drawing. A deputizing childishness that grew because someone—much too soon— gave up his mission to be a child. Open the door, step in! In here there’s unrest in the ceiling and peace in the walls. Above the bed hangs a painting of a ship with seventeen sails, hissing wave crests, and a wind that the gilt frame can’t contain.

It’s always so early in here, before the crossroads, before the irrevocable choices. Thank you for this life! Still I miss the alternatives. The sketches, all of them, want to become real. A ship’s engine far away on the water expands the summer-night horizon. Both joy and sorrow swell in the dew’s magnifying glass. Without really knowing, we divine; our life has a sister ship, following quietly another route. While the sun blazes behind the islands.
You can get an old school mechanical thermostat as a backup. I've suffered a total frozen house disaster in a past place - most of the plumbing wrecked - because of a heat failure during the Christmas break (gas valve in that case though; a mechanical thermostat wouldn't have helped). That's what started the obsession with remote temperature monitoring - I was into DS18B20s before they were cool - and from there it was only a little bit more hacking to just take control as well (so I can control it over the internet the way I like it - ssh!)

Ah, we're talking about exactly the same thing. Just a question of how we phrase it.

> After lots of practice (perhaps less for you, since you are already accustomed to playing without a shoulder rest -- I wasn't yet), you can get it to a minimum even in Concertos like the Tchaikovsky.

I tried to go full Baroque first where I shifted around an immobile thumb. Despite having big hands, there's that down shift in the first movement of the Mendelssohn. I spent a few weeks trying to figure out how to reliably make that shift without using the chin, and never found a way.

So at this point I ideally only apply pressure to the chin rest when I need to do a downshift, and only just enough to keep it the violin from pulling away from my neck. I've found Ricci's recommendation of glissando scales to be a great way of training this (as well as so much else): ascend without touching the violin with your chin. Descend with as little pressure on the violin as you can manage.
I love this, and also the fact that I can control my devices from control center. Not having to open an app to turn on/off the lights is game changing
The poet Robinson Jeffers also did this. He'd walk around in circles composing his poetry. If he stopped...

Yes, but not right away. It took a while for the knowledge and processes to become established. Piracy wasn't what sank the Dreamcast. By the time piracy became commonplace, roughly mid-late 2000, the DC was already pretty obviously going to lose in the market to both the PS1 and upcoming PS2.
>I also see the deployment of those massive fleets of satellites in LEO to be suicidal.

Incorrectly, fortunately. First, remember space is big. At hundreds of km up, even tens of thousands of satellites are by definition spread across a greater "surface" area than the entirety of the Earth. There will be fewer of them then there are aircraft flying through the skies.

Second, you might find it reassuring to look up orbital drag. The atmosphere doesn't simply stop at some set point, but rather gradually thins to irrelevance (or arguably to the bow shock of the solar wind). But anything below 600-700km or so requires regular reboosts or else it will experience decay (eventually exponential) and burn up/crash (depending on construction and design). SpaceX is leveraging its launch capabilities to have lower satellites which don't last as long, but offer superior performance, eliminates many of the space trash concerns, and doesn't lock them into design decisions nearly as much.

I mean, is this really such a surprise? SpaceX of ALL players clearly has enormous vested interest in making sure space access remains straight forward. Like, that's their entire foundation of business. If LEO really was closed off, no more SpaceX.
I'm not into drones myself so forgive me if I'm missing something obvious, but I'm a bit puzzled by all of these comments about safety. What exactly do you see as risky in that video?

That drone is what, half a pound? It seems like the biggest risk is it hitting a pedestrian or cyclist (of which I did not see any), and could result in perhaps a single person needing to go the hospital.

Meanwhile that video shows a bridge full of a hundred vehicles with one ton+ curb weights, driving at one another, piloted by what are most likely bored inattentive drivers. Due to the vehicle weights, there's extreme danger to pedestrians (over a hundred thousand causalities per year in the US, deemed acceptable). Due to the large difference between weight classes of vehicles, there's a significant risk to the passengers of those vehicles. And it's kept in line mostly by voluntary adherence to visual boundaries and an expectation that drivers will hit the breaks if the vehicles they're driving at change course.
Old reddit gives far more information about each submission on the page and is lighting fast. Nu-reddit wants to be an instagram style mobile first feed app and you can only see one submission at a time. Clicking on the comments is maddening because it doesn't even show all the comments before ending and suggesting other posts from the subreddit. If I wanted to see them then I would click on the subreddit hyperlink. Additionally it only shows the first node of depth for each op content so I can't follow the conversation without clicking again.

Wow, I literally just watched his [Turing award acceptance speech](https://youtu.be/I1lf2MBy3J4) last night. Horrible news.

I remember thinking, it’s so difficult to pick one subject to dedicate your life to. He chose software verification and model checking, and made a ton of advancements in that space. He was also very willing to give credit to the people who helped him and who he built his work on top of.

I hope he felt that he made a meaningful impact on the world. That’s all you can ask for I suppose.
Just my anecdote - I usually shop at Kroger owned stores (various brand names depending on your region of the US). Their "normal" prices are about the same as any other non-discount grocer like Safeway, but they're very aggressive with large discounts for store "members" who use their tracking card.

For example, when I shop, I'm not that particular to specific brands, so if I'm buying soup or cereal, I will always choose the one that is on sale that week, usually around half price (e.g B1G1). I end up paying about 60% of what a normal customer pays who is loyal to specific brands no matter if they're on sale or not.

What I've noticed is that the normal prices haven't really gone up all that much, but the discounts are very small and there are far fewer of the really good ones (e.g. $3 per lb. of chicken, the $0.99 carton of eggs, half price cheese, B1G1 soups, etc).

Thus, I'd say my grocery bill has gone up about 50% or more in just the last year, whereas it had really held stead for the last decade.

This is, of course, on top of home prices in my area nearly doubling in 10 years when considering increased taxes, HOAs, repair costs, etc.

>Have "can't fail" safeties.

I am lucky enough to have a couple of mercury thermostats for this purpose but I don't think I can get any more of those at this point. New "mechanical" thermostats tend to be actually electronic, some with a embedded battery that will eventually go dead.
That entire writeup is a scathing indictment of C++'s template system. It just gets progressively more horrifying and less understandable the further you read, until you're left with a mess of angle brackets, scope resolution operators and a pounding headache.

Yes, buying chips from Xilinx would be a bit like buying CPUs from Intel, not like buying a complete turnkey solution from MobilEye (which I realize is also Intel).
At a company where I worked, red badges indicated someone was a contractor. Everyone else had a white badge (sometimes with a colored marker for certain kinds of access).

"Red badges" were routinely made fun of and hazed. A pretty high percentage would end up getting hired full-time and the hazing would stop, so it wasn't exactly "personal", but it was definitely kind of weird.

(I have no clue what a red badge indicates at Amazon, though.)
To your point about sheets, I once purchased a supposedly-new white bedsheet that was not only torn, but soiled with small spots of some red/brown (blood?). I was obviously resold a used item.

I was so disgusted that I still remember this was when my perception of Amazon changed. It wasn’t the last time I would be disappointed by item quality. I still use Amazon, but mostly for consumables these days.
The central point of your comment is obfuscated by unnecessary condescension.
'Talking to yourself' makes it sound mad. I prefer 'vocalizing'. I find it's helpful when trying to objectively consider your own thoughts.
15k could be cost to the company, which also looks at employment taxes, office space, health insurance, benefits, hr/support overhead, interviewing, training and managing. A new developer earning 8k/mo easily costs the company 15k/mo.
It sure is an interesting instruction to implement. I can only assume that someone, somewhere, has graphs of commonly executed code sequences and concluded that there was merit in supporting Javascript's requirements in the ISA.

> During and after the economic collapse of 2007-2009 I wondered who was at fault; who to blame. I kept waiting for a clear answer to "THE root cause".

Well, there can be a difference between "who is at fault" and "THE root cause". Quite a large difference, potentially.

In the case of '07-'09, maybe nobody was at fault (seems plausible) but there was a very neat root cause. The government handed out a lot of money to people who shouldn't have gotten it, the people responsible were largely protected from bankruptcy and the system forced to reform largely as it was. The people who took excessive risk earned an excessive reward - they should have all gone bankrupt. The financial system should actually have changed, and people who made productive investments and didn't take risk should have become ascendant. Instead we have the same old crowd playing the same old game.

Disabling the major feedback mechanism of capitalism is about as root-causal as can be gotten. Nobody in particular chose to disable it though, it was a consensus decision among the powerful.
> The fact package managers exist proves my point: deciding which files go where is a big deal and there seem to be an awful lot of opinionated package managers making different choices here.

Consider that "package managers" only really existed in the UNIX world until relatively recently. Other OSs just didn't make everything so complicated to begin with.

"which files go where" just isn't really a problem if you don't make dependencies some third party's problem.
This isn’t really “testing”. It’s just signing up for their own service. They aren’t making stripe transactions and then reversing them.

If stripe bans you from buying your own service, they may want to rethink that policy.

The title does not do justice to the article. What a wonderful story that had an Indiana Jones quality to it.
$200/mo across the time is like the cost of one developer laptop accidentally left under the dripping faucet of a hotel sink in Las Vegas. I know this stuff can add up and people should be careful about racking up recurring charges for stuff they're not really using or getting much value out of, but optimizing away $200/mo doesn't seem like a huge ROI.

If you're paying people on your team, the most expensive thing you probably buy is a person/hour of time.

What’s your opinion on the scalability of formal methods? Isn’t it still the case that basically formal verification is impossible to do for larger code bases (like at least 10-100x that of sel4 in lines of code) and even sel4 took many many years and experts?
there's a difference between giving his words weight vs taking it as gospel though.

I think it's fair enough to do the former, even if i don't agree with them, and likely won't change my mind in this case.
For anyone looking to tinker with automating their thermostat, I highly recommend looking at the OpenTherm Gateway[1] (OTGW). It uses the OpenTherm protocol which is supported by a lot of heating systems.

Though the protocol is backwards compatible with the old type of thermostat which would simply turn on and off for heating, OpenTherm works with modulation as well. Not simply turning the heating on at 100% capacity and turning it off again when the target temperature was reached, but taking a bit more of a gradual approach.

The OTGW fits in here beautifully. It sits in the middle between your heating system and your existing (OpenTherm-speaking) thermostat. Listening to all the messages being sent between your heating system and thermostat. And if the onboard firmware fails, it should even fall back to that behavior completely.

For me, it allows to get a ton of information from my thermostat and heater, and automate heating and cooling down my home. All in a much better way than a simple relay with an ESP8266/ESP32 could do. It also retains my (non-smart) home thermostat functionality, including the ability to change setpoints on it. Which is much appreciated by my partner.

Third party support for the OTGW is relatively good as well. Home Assistant and Domoticz both support the OTGW, and the serial protocol it speaks is quite simple as well. Best of all, its opensource and has no need for any cloud connection you don't want.

Originally MIPS (or DLX) was the dominant architecture used for teaching computer architecture because the standard Computer Architecture textbook (by one of the main designers of MIPS, David Patterson [1] along with John L. Hennessy [2]) was used in most universities [3]. These two authors were basically the university-lead designers of the RISC philosophy. Patterson's team designed the RISC-I and RISC-II processors (Berkeley RISC [4]). Hennessy and his team designed the MIPS processors (Stanford MIPS [5]). This culmination eventually begot the RISC-V. So yeah, the RISC-V is now the dominant architecture used for teaching computer architecture as they now use RISC-V to teach computer architecture with their latest book edition [6]. Also for more information on that, read [7].
