Perhaps a unifying way of saying this is: it's a research problem to figure out how to get ML techniques to the point they outperform existing heuristics on "hard" problems. Doing so will result in engineering improvements to the specific systems that need approximate solutions to those problems.

I completely agree about the importance of imperfect information problems. In practice, many techniques handle some label noise, but not optimally. Even MNIST is much easier to solve if you remove the one incorrectly-labeled training example. (one! Which is barely noise. Though as a reassuring example from the classification domain, JFT is noisy and still results in better real world performance than just training on imagenet.)
Huh. I honestly thought AIX was dead by now. I remember porting something to AIX 20 years ago, it wasn't fun. I guess IBM stuff doesn't die, it just gets more expensive.

Doubtless scrum can be imposed from above as a management tactic. This would open to more wider discussions about how power operates in workplaces.

I don't know if there is anything intrinsic to Scrum that makes this more common as imposition but there are certainly risks involved in it that can push a negative power dynamic that is certainly possible in any undemocratic workplace. I'd have to reflect on this a bit more before answering.

But in a couple of cases I've seen it was sought by the team "from below" to protect the quality of their work, make work more enjoyable and self-organised and basically work to more reasonable timescales. There is something to scrum being a toolbox you can use and having a brand. It means you can ask for a process and people know what you mean. Rather than say "I wish work was better".
Is selective power off for individual DIMMs a thing? Not sure I want the power consumption of 128GB when I don't need it.

That's the kicker. BPF is simpler, _and_ in spitting distance of native code perf. And if you're doing something crazy like injecting user code into interrupts, you care about perf.

That being said, you're totally right that it's possible to get parity, just orders of magnitudes more work.

But it _is_ noon.

You are probably thinking of sun transit time, "solar noon", the moment in each day when the sun appears to be "highest" in the sky. This varies of course by position on the Earth, it's how people set "noon" when they didn't need to agree with anybody more than a horse ride's distance away what the time was. So, let's say at least 200 years or more ago.

Do you know when solar noon is where you live now? No? Because it's irrelevant. Huge numbers of people live in places where the solar noon changes by an entire hour twice a year for no sensible reason. Does this cause a huge problem? No, there's a slightly elevated rate of road accidents and things like that, but nothing major. A few seconds per decade is _nothing_.
The info page states that they are all periodic solutions.
Don't know why you're getting down-voted - it's a reasonable hypothesis. Why wouldn't a corporation reinvest those tax benefits?

I think that the likely culprit is a more competitive labor market in general, but there's no reason to outright reject the idea that the demand for labor could in part be driven by said tax cuts to a non-trivial extent.

At Microsoft the compiler team (Visual C++) and the Windows team are joined at the hip. I'm sure the same was true at Sun. This can lead to good decisions about undefined behavior that I hope would make Linus smile.

I recently learned of one such good engineering decision (I hope I'm remembering it correctly). Let's say you have a struct with an int32 and a byte in it. That's 5 bytes, right? But the platform alignment is a multiple of 4 bytes, so there's 3 bytes of padding (sizeof the struct is 8 bytes). If we stack-allocate an array of 11 of these and zero-initialize with = { 0 }, what would you expect to see in memory after initialization?

It turns out the answer was that the first element of the array would have its 5 bytes zeroed, but the 3 bytes of padding would be left uninitialized. Then, the remaining 10 elements of the array would be zeroed with a memset that actually zeroed all 80 remaining bytes. It sounds weird but this is a legal thing to do from the standard's perspective. All they're obligated to zero out are the non-padding bytes. This UB was leading to disclosure of little bits of kernel memory back into user mode because Windows engineers assumed that = { 0 } was the same as leaving the variable uninitialized and then memsetting the whole thing to zero. Nope!

The compiler team fixed this by always zeroing out padding too. Problem solved. There are some cases where it's not quite as fast. But it's the right engineering decision by the compiler team for their customers, both internal and external.
> In Tesla's particular case, the opt-in UX was even worse, because its automatic emergency braking wouldn't engage if autopilot was off [3] -- a decision contrary to sane user expectation, and completely unlike cars of other premium automakers. And the fact that their emergency braking still can't detect all stationary hazards in a travel lane is tragic.

AEB is very much running when autopilot is off, I occasionally trigger the warning when going down the parking garage(car thinks I'm heading head-on into another car).

Also after driving rush hour from Oly->Tacoma->Seattle for the last 3 years you can pry Adaptive Cruise control from my cold, dead hands. 75k mi and not a single hiccup or false positive.

The mental overhead of having to constantly evaluate vs intervene when someone merges into the lane/etc can't really be understated.
That's some pretty dubious logic, that is not completely backed up by reality.

And the idea that the split is governed by the value of labor at the time has also been debunked. Businesses everywhere are complaining of a labor shortage, yet they're not raising wages. I'm sorry, but the simplistic Econ 101 stuff isn't really applicable in the real world.

...let alone the ocean is actually not acidic but has a PH between 7.5 and 8.4, so if anything the ocean is becoming more neutral if there were in fact any basis to the argument.

This is a bit like arguing that global warming isn't real because places like Antarctica are really cold and any warming would just make the temperature less cold and not warm.

It really isn't very bad; Intel is very overpriced relatively if you're talking about e.g. $/core or $/thread at a similar TDP. The bandwidth in P9 chips is pretty high, and they have huge amounts of L3 cache compared to any price-comparable Intel purchase. They also have a significantly higher thread count (SMT4), and comparable PCIe lane count for peripherials vs up-to $8,000 xeons. The individual cores are also very fast: it's not like those ARM64 servers that tried to win by having many slow cores. The cores are fast, and there are a lot of them. Things like COTS networking blades and big-ass database servers are going to be their prime turf, I think.

I actually have an Excel spreadsheet open right now with some preliminary numbers (evaluating some random specs from a recent Anandtech article, along with Sforza CPUs, out of curiosity), and in terms of $/thread, the Sforza CP9M06, an 8-core 4SMT chip for $600, is only beaten in $/thread by a Cavium ThunderX2 9980-2200, at $18.5/core vs $14.02/core, thanks to 128 threads. But, at a price of $1,800, with a significantly lower base/turbo clock frequency (3.5GHz+ vs 2.2+) and less than 1/2th the L3 cache.

Granted, these numbers are more or less impossible to verify at this moment and unbelievably fuzzy, and it's incomplete without filling in all the data on a wider array of Xeons, EPYC machines, and real benchmarks. But the back of the envelope numbers come off as pretty solid, and my experience with POWER8 makes me think these machines will perform very well.

There is also the fact that IBM is quite open about POWER this time around, all the way to making all their firmware/boot/BMC code open, and encouraging patches, under FOSS licenses, and making all the architecture/firmware documentation freely available. Might not matter for hyperscale data centers that negotiate themselves, but certainly a nice bonus.

The biggest price-related barrier at the low end is really the cost of the mobos, though. That's where most of the TALOS II's price goes to. The CPUs are relatively cheap in comparison.

I think interactive models are fantastic for learning about systems and how they work. The thing is, it's difficult to design and create these types of models, even today (2018). I don't know that we have created tools that empower non-programmers to build such complex models.

Even knowing and understanding programming, you'll have to spend a considerable amount of time to create such interactive media. This might be worth it if you have an online learning company and you're selling educational content for mass audiences. For the one off technical paper or write-up, the dozens to hundreds of hours it might take to produce interactive media (assuming you already have those hard-earned skills) describing your topic is too much for most.
The discussion on radiology is extremely sloppy.

Andrew Ng claimed human level performance on one radiology task (pneumonia). This claim seems to hold up pretty well as far as I can tell. Then the person criticizing him on twitter posts results on a completely different set of tasks which are just baseline results in order to launch a competition. These results are already close to human level performance, and after the competition it's very possible they will exceed human level performance.

Yes it's true that doing well at only Pneumonia doesn't mean that the nets are ready to replace radiologists. However, it does mean that we now have reason to think that all of the other tasks can be conquered in a reasonably short time frame such that someone going into the field should at least consider how AI is going to shape the field going forward.

Not for everything but Walmart is cheaper on many things. Amazon used to be the cheapest but that is no longer the case. People just assume Amazon is the cheapest for some reason but they’re just the most convenient.
Even in tech, plenty of corporate teams such as sales, marketing, HR recruiting, etc. are populated with people who had social sciences or liberal arts degrees. Not all of them majored in business. So long as their program taught them how to read, write, and speak publicly, it's better than no degree.
It should, since the banks need to be constantly refreshed. I think the bigger power consumption for standby phones is RAM.

Not everything is a conspiracy.

Colon and rectal cancers have increased 51% among adults under age 50 since 1994, the cancer society said.

That isn't a white paper.

> If you make most of your money off removing polyps

Preventative medicine is cheap. In accordance with the ACA, polyp removal is guaranteed to be covered if discovered during a colonoscopy. Don't want it removed? Maybe it becomes cancerous. Now you've moved on to curative care. Cancer medications can cost over $100k. Surgery to remove the colon is $35k+. These are just small pieces of a larger puzzle including other treatments, readmission risks for related illnesses, etc. Now you're done all your treatment and you've moved on to palliative care. If treatment succeeded, you have costs associated with the constant infections related to a colostomy bag. If the treatment fails, now you have the costs associated with end-of-life care.

If you want your conspiracy to hold some weight, they would be pushing the age in the other direction.

Yes, DRAM cells have to be refreshed every 60 ms or so. More RAM means more cells to refresh which means more power consumption.

> horrifying casual sexism that others have highlighted

Horryfying? You think that this is 'horryfying':

"This is not easy to explain to women and the mechanically innocent."

It's 1958. And yes most women (and especially at that time) tended to be less interested in mechanics. Not to say that there weren't women who were but nothing wrong in stating a point like that. Nobody cared back then either. And it wasn't horrifying that is a big exaggeration.

I watch a TV Show on Jet Airplanes. My wife has zero interest in watching that show or anything related. Ditto for my daughters and for that matter any past girlfriend. Of course there are women who watch and enjoy the same show. But I would love to bet anyone that the number of men far outweighs female interest.

Separately women make jokes about men and sports. That isn't to say that all women don't like sports or all men do. It's just a generalization that is rooted in truth and there is nothing derogatory about saying that either.

Is there a guide/reference on how to disable these optimizations in modern compilers? A list of GCC/Clang arguments that disable as much of this as possible would be greatly appreciated. I've seen a lot of posts and articles discussing C undefined behavior but almost nothing describing how to counter it.

Governments in the US have never taken up the responsibility of ensuring that everyone can get a post secondary education.

There's historically been substantial investment in universities and colleges, but that was always about increasing the number of people with those educations (economic development in other words) and never about universal higher education.

Nowadays there's lots of people pursuing professional education and the support available to each individual has been declining (this may still cost lots more than higher levels of support that existed when fewer people sought degrees).

But how does one go about raising seed? Forget pitch decks, pro formas, competitive analysis, and warm introductions - we have all that. I mean what's the actual proess look like, detailed? How can we learn to pitch (properly) to real VCs? Are there resources that are things like filmed/real pitches?

Basically... having read a tonne of this online, we're wondering how we go about doing it? How do we specifically set the valuation? How do we raise this seed/series A? Which is it? Thanks in advance for any responses, I really appreciate it!
>the kind of people who value that are unlikely to stop shopping at Walmart because of the negative PR

Walmart isn't worried about losing the people shopping at Walmart. They just need to continue to sell cheap food, clothes, and household things in order to keep them.

Walmart has always promoted from within. I bet very few people have worked part time in Walmart for 1+ year while going to college for a business degree and not been shortlisted for a promotion. The college subsidy will give them more managers with ground floor experience.

Walmart is very concerned about how to grow their customer base. You see this with the 2day online shipping, site to store, and their grocery pickup program. The increase in wage is a direct attempt to increase employee retention and attract better employees. This is about growth, not loss prevention.
Did you ever noticed that when it comes to protect a public official, for example a cop killing someone, all the State pieces work in perfect synchrony? I mean, everyone, from lawmakers, judges and the lowest of clerks suddently learn how to make exceptions and interpret the laws in new ways.

Yet, I have to believe that lawmakers aren't able to stop billionaires from screwing up the small guy without making complex regulations that impede progress and innovation, regulations that in the end make the rich and the bureaucrats a lot of money and sink hopes for the honest entrepeneur.
