Sort of, but not really. From the original report:

> It was the decision to cease the processor operation which finally proved fatal. Restart is not feasible since attitude is too difficult to re-calculate after a processor shutdown; therefore the Inertial Reference System becomes useless. The reason behind this drastic action lies in the culture within the Ariane programme of only addressing random hardware failures. From this point of view exception - or error - handling mechanisms are designed for a random hardware failure which can quite rationally be handled by a backup system.

> Although the failure was due to a systematic software design error, mechanisms can be introduced to mitigate this type of problem. For example the computers within the SRIs could have continued to provide their best estimates of the required attitude information. There is reason for concern that a software exception should be allowed, or even required, to cause a processor to halt while handling mission-critical equipment. Indeed, the loss of a proper software function is hazardous because the same software runs in both SRI units. In the case of Ariane 501, this resulted in the switch-off of two still healthy critical units of equipment.

> The original requirement acccounting for the continued operation of the alignment software after lift-off was brought forward more than 10 years ago for the earlier models of Ariane, in order to cope with the rather unlikely event of a hold in the count-down e.g. between - 9 seconds, when flight mode starts in the SRI of Ariane 4, and - 5 seconds when certain events are initiated in the launcher which take several hours to reset. The period selected for this continued alignment operation, 50 seconds after the start of flight mode, was based on the time needed for the ground equipment to resume full control of the launcher in the event of a hold.

> This special feature made it possible with the earlier versions of Ariane, to restart the count- down without waiting for normal alignment, which takes 45 minutes or more, so that a short launch window could still be used. In fact, this feature was used once, in 1989 on Flight 33.

> The same requirement does not apply to Ariane 5, which has a different preparation sequence and it was maintained for commonality reasons, presumably based on the view that, unless proven necessary, it was not wise to make changes in software which worked well on Ariane 4.

> Even in those cases where the requirement is found to be still valid, it is questionable for the alignment function to be operating after the launcher has lifted off. Alignment of mechanical and laser strap-down platforms involves complex mathematical filter functions to properly align the x-axis to the gravity axis and to find north direction from Earth rotation sensing. The assumption of preflight alignment is that the launcher is positioned at a known and fixed position. Therefore, the alignment function is totally disrupted when performed during flight, because the measured movements of the launcher are interpreted as sensor offsets and other coefficients characterising sensor behaviour.
After reading the article, I think my anecdote is still relevant, and that the article reinforces it. As @the_duke surmised: If you don't understand your tools, you can use them so inefficiently that other, supposedly worse tools are much faster.

The article doesn't mention what versions of each compiler was used. I'd also challenge the author to use Compiler Explorer to discover compiled-to-assembly-level differences between their C and C++ code.

I had assumed that Jeremy Grantham was investing his wealth to save the planet, this was the conclusion that the author presents at the end of the article under the title "Bottom Line".
But this is not necessarily the case, Mr. Grantham is investing in technology that will show a profit because of climate change, it is a subtle difference but an important one to consider, sort of the grain of salt that should be taken with reading of the article.
Your requirements aren't necessarily the same as everyone else. For people who want something silent and inexpensive to run a few containers, rpi can be hard to beat. Extremely cheap, extremely low power and take up very little physical space.
This depends heavily on the age and wage of the employee. For a typical 20-something developer making $100k, the monthly cost for a good HMO might be peanuts at ~$300/mo., a mere 4% overhead.

But for the 60-year-old hourly line worker making $40k, whose wife and two kids are also covered by the plan (thanks union!), a good HMO might cost upwards of $2000/mo., an almost 50% overhead. [0]

For a PPO, the numbers would be even higher.

> For most people, that transition happens between the teenage years and adulthood.

No, I don't think it does. Certainly, you'll often encounter people going through the first phase of it (the discovery of and infatuation with libertarianism) in, say, the first couple years of college, but I don't think most people go through the whole arc (or even the first part) at all, much less most people going through it in the age window you describe.
The g-code variant my machines use contains most of the control structures of modern programming languages. It has variables, comparisons, loops, subroutines, the codes are all fairly straight forward and honestly a lot of g-code is produced automatically with CAM software rather than being written manually these days.

It's a simple language, you don't have to memorize the codes and you end up memorizing the few you use most often anyway.

Honestly the actual math and figuring out the toolpaths for your machine ia far harder than writing the g-code for it.

Ask HN: What can we do about spam calls with spoofed numbers?
I received 14 spam calls in the past two days. I just called back one of the numbers and the person on the other end was not the person that called me. She told me that this has been happening to her too.

It looks like spammers are using other people's numbers to make these calls. What can we do to stop this?
So I ride bikes and always monitor my heart rate while working out.

I've always used a chest-based heart rate sensor until I started trying wrist-based about 4-5 years ago. I've used countless brands and models (ranging in price from about $49.99 up to about $399) on my wrist - and literally none are as accurate as the chest-based strap. The chest strap responds immediately to increases and decreases in heart rate. Whereas the wrist sensors always seem to lag, sometimes by up to a minute or so.

The wrist-based sensors always seem to differ depending on where on the wrist they are worn - high, low, inside of the wrist, outside of the wrist, etc - by maybe 5 bpm or so.

In either event, if you really want to test the accuracy of the wrist-based sensor, you should really compare it to the output of a chest-based strap.

In fact, the results will largely be personal - because the electric signals may differ per person greatly in different areas of the arm.

Needless to say, my apple watch is worn daily, but when riding, I have gone back to a chest-based strap.

That all being said, there is a guy that reviews these gadgets and will often wear 2-4 sensors while working out, and post an overlay of the results from his workouts. The baseline should generally always assume that the chest-based straps are accurate. His site is called DCRainmaker, if anyone wanted to look up his comparisons/reviews.
> For example, when women started to enter the work force starting in the 70/80s, it lead to a dramatic rise in prices.

I agree with the earlier point about inflation due to free money, but this one doesn't follow.

Women mostly entered the workforce during the war. Not to mention cheaper labor (which would happen if more labor enters the workforce) should actually cause the prices of goods to drop, not rise.

However in case of UBI, labor pool isn't being increased (it's being shrunk), and more money is being given to that segment of the society (taken from other segment of the society), which would mean the prices for the goods which these people wanna buy would go up.

When I tried on an Apple Watch at an Apple Store, I noticed that the heart rate it displayed was definitely different from mine.

I mentioned it to the employee who was manning that table, and she told me the demo watches had some pre-programmed data for demo purposes.

I was puzzled by this since heart rate monitoring is a key feature users care about. It occurred to me that heart rate data of everyone who has tried on the watch might count as the kind of medical information you shouldn’t publish on demo watches.

Imagine ridiculous stories like “CEO of X’s heart rate was 130bpm when he tried on the new Apple Watch, says journalist who tried it on right after.”

Ask HN: Embedded Database Design Papers
In order to learn more about database design principles I thought it would be great to read papers on embedded databases. I have searched around for material on the popular open source databases like RocksDB, LMDB, or LevelDB but haven't found anything concrete. Aside from reading the source code, how can I teach myself about the data structures and abstractions that these provide? Eventually I would like to write a toy implementation after getting acquainted with a subset of this knowledge.

Spindle crashes are terrifying. I've had a few. I've destroyed tools and pieces. Cost thousands of dollars in damage from a single misplaced tool path or lead in/out.

There's also this very transitive nature to the programs. Unless you make a whole bunch of the same pieces your programs tend to be one time use. 99% of the things we make in our shop are fully custom meaning brand new programs for every single table.
Yeah, I think most people would be surprised to learn that the same blood tests done by different labs can sometimes show 10% difference in values or even more. This could be the difference between a doctor declaring someone "within the normal range" or having a health problem.
Right before they ask “why arent you married” and “when are you having children”?

I hung out with a quite left-leaning bunch of neo-hippies, hipsters, trad musicians, techies, hackerspace people. The blue part of Houston, basically. At one point, I was dating a neo-hippieish woman and was invited to one of her parties. The assumption in conversation was that everyone had kids. It's not necessarily a social conservative thing.

Texas is pretty diverse, though. Did you know there's a significant German speaking community there? Lots of them come from a group that ended up there because they were a community of staunch abolitionists trying to move away from governments that supported slavery. (That part didn't work out, though.)

I would say that Houston is sort of "working man's cosmopolitan."

Because it's a proprietary Verizon standard that is different from and not compatible with the standard that the 5G committee is producing.

We have an interesting relationship with taxes.

We have no state income tax, and our gas tax is low enough to force most new highways into being toll roads, but our property taxes are sky high.

In fact, we have higher property taxes than California. Now, because property is so much less expensive here than in CA, you still have cheaper housing costs, but in Texas a much higher percentage of that is tax.

I think you are oversimplifying.

Your conditions don't really account for Minnesota being #3 on the list. As a Minnesotan I'd proudly describe our state as high-tax, having an appropriate level of regulation (aka much more than Texas), community focused, with lots of interest in finding smart government way to fix lots of social problems. Just another way to get to being a better place for women entrepreneurs.
Of course, the more you can activate recollection from that specific event the more data you can gather to reconstruct the whole.
They're not high enough. And while there are gasoline taxes at the pump, there are various subsidies on the extraction and refining part of the supply chain. I'm not sure the taxes cover the subsidies. It's a wealth transfer from consumers (the ones buying gas) to the producers (the ones receiving subsidy)
I would interpret the article as one with the following abstract:

C++ has a lot of generic programming solutions like std::vector and algorithms, [and we think of these things as being fast even though they are generic because of templates and “zero cost abstractions”] but we show that we still pay for their being generic (because they must support operations which make everything else expensive, or are doing more work than we need done), and so [for situations like this] we prefer the trade-off of implementing specialised functions that may be similar to other functions elsewhere to gain runtime and compile-time performance improvements. We demonstrate this thesis with a case study of a mash simplification algorithm.

I think this is a reasonable topic to write about, and I think the article does an ok job of it. I think it is silly to get hung up on specific cases (e.g. you need to do some magic custom allocator thing to make a c++ thing about as cheap as a c thing that achieves the purposes you have, or that you might want to replace an exact sort with an approximate one (note that in this case, using a full radix sort would have you pay 30ms instead of 10, so 572 -> 340ms which is still a large improvement, and one that will become larger with larger inputs)). I think one should instead treat it as a case study which shows some general ideas like “you often do pay for what you don’t use in c++/stl” or “often one can use a more specialised algorithm with much better performance then a general one so when one is writing performance sensitive code, having generic algorithms to hand may not be useful”
Wow. Bigoted much?

I'm confused by the premise:

> dropping C++11 requirement allowed me to make sure anybody can compile the library on any platform, removing std::vector substantially improved performance of unoptimized builds

What platform doesn't have C++11 support? And why is the performance of an unoptimized build interesting? -O2 is basically a standard compiler flag...?
This "study" is yet another in a long line which look at things they think should drive business growth, rather than looking at actual business growth. It's basically a list of states that have the most right-wing public policies.

The most relevant factor -- number of female owned business -- is only weighted 25%. It mentions that 20% of businesses in Texas are woman-owned, but it doesn't provide numbers for any other state for comparison.

Lucky for us, the National Association of Women Business Owners has commissioned a more accurate study of the subject:

Why is elitism implied to be a bad thing in this context? Professional standards and ethics are something we should strive for, right? For those to work, you have to discern between people who uphold those standards and people who don't.

There are places where egalitarianism is most appropriate, e.g. in tallying political interests, and where elitism is most appropriate, e.g. no one wants an amateur surgeon.

Even if they want to open the group to hobbyists, as a professional I have more in common with a hobbyist who actively maintains a software project than one who doesn't actively contribute; specifically, if you're having a discussion about software you're largely on the same page with the former. That's ultimately the point of association, it's to improve conversation by gathering people who have a shared understanding.
