Absolutely. And if they had done that I would have been dutifully impressed, but they didn't. They just calculated average kWh output for a block of wind turbines, which is just using the weather forecast and monitoring turbine output. I didn't realize this until I read the article more carefully (see my other comment). Small steps, I suppose....
You've clearly never built a deep network architecture and trained it. Success is highly dependent on both domain expertise for the problem you are trying to solve, as well as a strong math and statistics background. Sure, any Joe can use TensorFlow and make a small CNN to classify their family photos, but building something that can beat world champions at Go requires teams of experts.
Ah, ok, so I actually read the article (no I'm not new here). And it even says it right there in the summary, but somehow it didn't register. They are predicting wind power generation, not the wind itself!
Definitely not as impressive as my first reading. They are even using existing weather forecast data, so nothing particularly innovative here. I think there is a lot of potential to do something really cool in this area with DeepMind, though. There is a ton of historical and real-time data available.
What you are talking about? Most weather pattern prediction services just use the NWS's GFS, including Windfinder (it even says so right in their FAQ).
The DeepMind approach is completely different. A 36 hour forecast isn't exactly amazing, but it's just the beginning.
It's not guessing, but it's not strictly a model-based calculation either. Wind speed and direction, in particular, is a very complex system of equations (computational fluid dynamics) that doesn't scale reasonably at all if you try to use a physical model. So the field has been trending toward statistical models and stochastic simulations for a number of years. DeepMind can effectively do both, but on steroids, and it works well because of the enormous amount of data available.
At $200k/yr I got $5326 take-home bi-weekly, which is about $10,652/mo. That's 36% withheld for taxes from a gross paycheck of $16,666/mo, which sounds about right. Mind you this amount can change significantly depending on your allowances, deductions, and filing status, but it works for crude estimates.
If your rent is $3000/month then you need to take home $9000/month to be out of the poverty zone,
Uh, what? That's crazy, think about it. I know you're using the 1/3 rule, but while it is good advice there are plenty of caveats. The main one being that it doesn't scale linearly. If you are a single person making $900/ mo and spending 300/mo on housing, the remaining 600/mo could easily be spent on food, transportation, and incidentals. So spending more than 300/mo on housing would be pushing you into the realm of unaffordability.
But in your hypothetical case of a single person making $9000/mo and spending $3000/mo on housing that leaves $6000/mo left for "not housing." If you dump 1/3 of your income into retirement, which is highly recommended, that still leaves $3000/mo, which is quite a lot. So that's why you'll see people at this income level often spend significantly more than 1/3 on housing. Whether that's affordable depends on what you need the rest of your income for. If you are paying off lots of debt (ex: med school loans), you won't find it affordable. But if you are mostly debt free, you can spend more on housing easily and probably also still afford a tesla.;) Either way, it is nowhere close to poverty.
which according to a pay calculator I found requires an income of $375,000 in California.
You clearly don't know how to use that pay calculator then. If your numbers were right, your hypothetical person would be having a ~2/3 withholding from their paycheck, which is ludicrous, even if you consider all levels of taxes and things like the AMT. A single person making ~$200k could theoretically be taking home ~9k/mo after withholding, which is a high, but not crazy salary. Two people living together could easily make that as joint income.
No, but as I heard one nurse who worked on the Labor floor describe it: "I love my job because I work with patients who aren't sick." Presumably you understand the required hours before you take the job, but even OBs get time off.
Agree with your general point, but this whole discussion seems to be a little confused about nitrates vs nitrites vs nitrosamines, so a quick chemistry overview for some clarity:
Nitrates (most oxidized form) -> nitrites (two-electron reduction of nitrate. Outside of industrial processes only occurs biologically by the bacterial enzyme nitrate reductase) -> Nitrosamines (reaction of nitrites with secondary amines. Requires heat and/or acidic conditions. These are generally stable compounds.) -> Hydroxylated nitrosamines (Unstable intermediate formed by enzymatic processes that mostly occur in the liver) -> Nitronium cation (spontaneous breakdown of the hydroxylated nitrosamine. Cation is an alkylating agent that can modify DNA.) -> DNA damage -> DNA repair or cancer
The basic gist here is to illustrate that there is clear mechanistic reasoning behind the notion that nitrates have a cancer risk associated with them. But it also illustrates that the transformation is complex and there are multiple ways for harm to be mitigated long before a cancer risk is ever truly a risk.
For example,
Sodium nitrite in food cooked at high temperature with high protein content -> skips step 1 and facilitates direct production of nitrosamines that get ingested and transformed in the liver
Sodium nitrate plus antioxidants -> hinders production of both nitrites and nitrosamines -> lower risk of being transformed in the liver
Nitrates in vegetables -> typically have low protein content and lots of antioxidants, so low risk of producing nitrites or nitrosamines
Celery juice -> naturally occurring nitrates -> no intrinsic risk of being converted to nitrites, especially if antioxidants are also present
Celery powder -> evaporated celery juice (same as above)
Cultured celery powder -> celery juice that is treated with bacteria and then evaporated -> this causes the nitrates to be converted to nitrites (by the bacteria) and presents a direct path to nitrosamine production if used to treat high protein content foods (aka meats)
Bacon -> depending on above may have varying levels of nitrites or nitrosamines present after cooking, but generally low levels overall -> likely a low cancer risk, but may present a higher risk depending on frequency of consumption and other dietary factors
Celery, arugula, beets -> high in nitrates, but no nitrites or nitrosamines present, even when cooked in the presence of meats (ex: stews) -> low, probably non-existent, cancer risk
Cigarette smoke -> high concentration of nitrosamines inhaled directly into the lungs -> the nitrosamines still have to make their way to the liver, but represents a moderately high risk of cancer, especially considering the often habitual and frequent nature of smoking
Uh...yes, as I said strict confinement is a purposefully-built security feature of snaps. Classic confinement is intended for developers and is not recommended, but nothing stops you from using it if you want. The easiest solution would be to just bind mount your NFS share into/media as I suggested.
The SNAP version of VLC on Ubuntu doesn't work to play video files mounted on NFS, and hasn't been able to do this for months after the bug was posted.
It's not a bug. The VLC snap runs under strict confinement which prevents it from accessing files outside of/home/$USER or/media. If you have an NFS mount that you want to access, you just need to bind mount it into one of these two locations. You can also switch to classic confinement if you don't want to restrict its ability to arbitrarily access your filesystem.
3) Jupyter doesn't encourage enterprise deployment. Too often I see experimental data science done well, but due to the nature of rapid development, nothing is modular, nothing is object oriented,
I'm not aware of anything like this that works generically for Jupyter notebooks, but I've been using OpenCPU to provide this functionality for R. RStudio is kind of like Jupyter, but designed more specifically for R, and it has templates for turning R scripts into packages. So you start with R Notebook, modularize into part Notebook / part R script with embedded functions, the Notebook part can be bootstrapped into a basic UI, then wrap up everything in an R package and deploy with OpenCPU. It's not quite seamless, but can probably be made reasonably easy with some unifying glue code to be used across packages.
I agree with you because I'm in the same basic situation as you: surrounded by subject matter experts who need to learn to do some data science. Getting the tools in their hands to help them along the way is a persistent need. If you don't, they just go back to using Excel (or whatever) and that is truly a nightmare to manage.
64-73% of the cost of living differences in US states are due entirely to government policy decisions.
It affects it some, but no, the majority of the cost-of-living differences are due to economics. The key driver, housing, is inflated entirely by economics. More people want to live in SF because it is a desirable city and they work for a companies that pay excellent salaries and benefits. Those people turn around and spend that money on housing, but housing is a finite resource and supply-limited, so as demand increases price increases up to the point where some fraction of people can still afford it.
Yes, more housing helps some, but there is limited available space. And people don't want to live in high-density shitholes. They want to live in nice houses with land, quiet neighborhoods, with good schools, safe and low crime, some want to be near nature, others want to be near cool restaurants, etc. If your proposal is, "let's build a bunch of high-rise skyscrapers in the middle of your nice residential neighborhood", then yeah, expect people to fight that.
Finally, most of the infrastructure problems are the result of excessive government debt.
Great analysis. And why does the government have excessive debt? Because well-conceived programs with long-term plans and enough revenue to cover their costs are raided by politicians dangling carrots in front of lobbyists (pet programs, subsidies, tax cuts, defense spending, whatever) and sure enough, when those programs suddenly need that money for the circumstances that were planned for, now it's not there, it has been spent already on other things, and the only "solution" is to cut that program because it is too expensive and we can't afford it.
If you want to know where our debt comes from, look roughly in this order: Newt Gingrich, Cold War spending, medicare part D plus aging population (plus gradual increases in income levels with no adjustments made to FICA caps), Iraq wars (unfunded), bank bailout (not the loans, the cash that was handed out), the recession.
Look at the inversion which happened over time, as corporations (evil or not) moved their headquarters to other countries where the tax rate was competitive and much lower than here. Then look at what happened when the corporate tax rate was lowered.
That's not what happened. These companies kept their headquarters here, for the same reason companies still prefer to be in higher tax areas like SF rather than rural Iowa. They need the infrastructure, and the services, and the workforce that they get in the US. Otherwise there would have been a mass exodus to Iceland years ago, but that didn't happen. No, what happened is these companies engaged in a giant tax evasion scheme, where each company employed teams of lawyers and each tried to outdo the rest coming up with new creative means to avoid paying any taxes. GE a multi-billion dollar revenue company famously paid zero taxes as a reward for their efforts.
Think about that for a moment. A company generating hundreds of millions of dollars in profit is siphoning that money off to their execs or just coming up with ways to sit on big piles of cash (no they aren't reinvesting it; that would be tax deductible), while you foot the entire bill for things like Medicare/Medicaid and the Iraq wars and the bank bailout. Apple has so much hoarded cash right now they could never spend it all. They built a new building with it (yay), that used up maybe 0.1% of their reserve. They could stop making products tomorrow, and burn cash reserves long enough to let Tim Cook and all the other Apple execs and senior shareholders walk away with a nice parachute.
A company that wants to use its money to grow, or invest in new business opportunities, or pay bonuses to their employees, or pay dividends to their shareholders, or buy back stocks...all of that is fine, it's a great use of their money and they should be allowed to do that pre-tax, which they do. But if they just want to sit on a pile of cash, no. Pay a relatively small percentage back to society so that it can function properly and so the government doesn't have to keep adding to the debt and even maybe so tax rates can be lowered on wage income!
He had cracked the puzzle just five days before it was set to expire.
Cracked the puzzle?!! I'm sorry, but this is just stupid. There was no puzzle. The supplementary document provided by Goldman provides a precise specification for how the files are encoded. The only thing an interested person had to do is just apply that specification to a decoding task. Happy for the grad student, though, who has probably doubled his income this year.

So, works for me. As you said YMMV, but quirky system-dependent issues are difficult to debug. I'm not so quick to blame Canonical for a package that passes all
This is not the same problem. His configuration file is fine. Not sure what the problem is in this case, but plenty of people install mysql-server 5.7 on fresh 16.04 without encountering it. So suffice it to say it is probably something weird to do with his particular circumstances, maybe the slightly odd Microsoft Azure configuration. Weird stuff happens in VMs sometimes, especially on cloud services.
FWIW, I don't agree with the sibling poster. I think companies, like Canonical, are best served by supporting their ecosystem as best they can, including for non-paying users, but they can't support every combination of every package. Nobody does that. If you were having this problem installing on Windows, would Microsoft provide free support? No.
I wasn't finger pointing, just trying to explain your observation (marked as unassigned bugs), and I think it is reasonable. If you don't agree, please explain why instead of attacking with expletives.
The packages are stable. As I tried to explain, and you apparently missed, the problem with mysql-server is due to an upstream change. The software and packaging are not broken. The bug report refers to a problem during a major release upgrade. It was known possible issue that a user might encounter during upgrade reported in the release notes and is recoverable, so not generally something considered to be a show-stopper, by anybody. The problem with libreoffice was experimental functionality that the user enabled and is known to have problems. Solution: don't enable it. Again, not a show-stopper bug.
They are not ancillary systems: they are core functionality
That may be, but a commercial company cannot offer free support for every software package that someone considers "core functionality". Red Hat certainly doesn't. If you are having a problem with a package that is not in the "main" repository, and you haven't purchased a support package, you are left with community support only. This is clearly stated on their website, https://help.ubuntu.com/lts/se....
Your first link is to an issue encountered during a release upgrade. Release upgrades are tricky and nearly impossible to get perfect, especially when the software involved (in this case mysql-server) is complex and had an upstream change that affects configuration settings. There will always be edge cases that fail in these situations, and it is not necessarily worth it to try to fix every edge case as long as it doesn't corrupt data and the user is able to fix the problem manually. In this case, the upstream mysql-server change was noted in the release notes, so users upgrading should have been aware of potential problems going into it. The packaging of mysql-server-5.7 itself is not broken.
In your second link, the problem is an issue with the OpenGL rendering support in libreoffice and is likely hardware/driver dependent. It is not something Canonical is in a position to fix.
Also, both of these packages are in the universe repository and not officially supported by Canonical. So what you are getting from these bug reports is community support, which is why they are unassigned and don't receive much (if any) attention by a Canonical employee. I agree Debian is much better in this regard, but there is only so much a single company with a handful of employees can reasonably do.
Mitt Romney is one of the smartest presidential candidates this nation has ever seen, as well as a fundamentally decent human being. People tore him to bits over offhand comments and talked endlessly about his unforgivable sin of having - 30 years prior - taken his dog on vacation. (One New York Times columnist published no less than 86 columns talking about that incident, which seems like obsessive enough behavior to qualify for institutionalization.)
Agree (I usually ignore Gail's columns because she rarely has anything interesting or useful to say about anything). However, Mitt Romney did it to himself. He may have been smart and decent, but he grew up a privileged life and he was way out of touch with his base. He tried to portray himself as a "man of the people" by going to county fairs and eating corndogs, but it backfired on him. His Republican competitors in the primary did far more damage to him than Obama in the general.
Yes, there are multiple serovars of S. enterica, but you are mostly picking nits. Salmonellosis, of which (para)typhoid fever are particularly severe forms, is caused by S. enterica, which is transmitted via infected food/water. What we call "food poisoning" is just a milder version of salmonellosis that we can often recover from without antibiotics. In the present day, the epidemiological relationship between serovar and fecal contamination of drinking water points to how severe salmonellosis is most commonly spread, but the reservoir for the disease still has to exist, and 500 years ago this could have easily been domesticated animals.
Yeah, for some reason that feature doesn't seem to work in the new Firefox 57...at least not for me. I do remember using that in the older versions though.
No, it's not acceptable to refuse to boot because of such a bad entry.
Why is it acceptable to continue booting even if there is a bad entry and ambiguity as to whether the entry is required or not?
You are biasing your preference on "it has always been this way" rather than a rationale for why that's a good idea. The systemd folks make a good case for why it's a BAD idea, and thus have decided to make boot fail when it can't bring up an essential volume. If you have non-essential volumes in you fstab you need to explicitly specify it. Very simple, straightforward, and not at all unreasonable, as is usually the case when someone brings up a systemd "defect".
Plus, the OT is right, you're beeing hostile just for the fun of it...
I criticized the OP for not reading some basic documentation, and not preparing properly for a system upgrade that he knew would make major changes to the previous userspace. Sorry if you consider that hostile, but in the old Unix days of yore, RTFM was a very common meme, especially here on/.

Replying to myself, but just wanted to answer the question posed in the summary:
Is this a blow to Big Blue who purchased The Weather Channel's Weather.com to showcase Watson
No. If this is the extent of Google's interest in this area (hopefully not), then Watson has nothing to worry about.
, or is it news just because it's Google?
It's not news. It's a blog post on one of Google's websites.

If you want to know where our debt comes from, look roughly in this order: Newt Gingrich, Cold War spending, medicare part D plus aging population (plus gradual increases in income levels with no adjustments made to FICA caps), Iraq wars (unfunded), bank bailout (not the loans, the cash that was handed out), the recession.
Just to add to your point. The GP sayeth,
Look at the inversion which happened over time, as corporations (evil or not) moved their headquarters to other countries where the tax rate was competitive and much lower than here. Then look at what happened when the corporate tax rate was lowered.
That's not what happened. These companies kept their headquarters here, for the same reason companies still prefer to be in higher tax areas like SF rather than rural Iowa. They need the infrastructure, and the services, and the workforce that they get in the US. Otherwise there would have been a mass exodus to Iceland years ago, but that didn't happen. No, what happened is these companies engaged in a giant tax evasion scheme, where each company employed teams of lawyers and each tried to outdo the rest coming up with new creative means to avoid paying any taxes. GE a multi-billion dollar revenue company famously paid zero taxes as a reward for their efforts.
Think about that for a moment. A company generating hundreds of millions of dollars in profit is siphoning that money off to their execs or just coming up with ways to sit on big piles of cash (no they aren't reinvesting it; that would be tax deductible), while you foot the entire bill for things like Medicare/Medicaid and the Iraq wars and the bank bailout. Apple has so much hoarded cash right now they could never spend it all. They built a new building with it (yay), that used up maybe 0.1% of their reserve. They could stop making products tomorrow, and burn cash reserves long enough to let Tim Cook and all the other Apple execs and senior shareholders walk away with a nice parachute.
A company that wants to use its money to grow, or invest in new business opportunities, or pay bonuses to their employees, or pay dividends to their shareholders, or buy back stocks...all of that is fine, it's a great use of their money and they should be allowed to do that pre-tax, which they do. But if they just want to sit on a pile of cash, no. Pay a relatively small percentage back to society so that it can function properly and so the government doesn't have to keep adding to the debt and even maybe so tax rates can be lowered on wage income!
He had cracked the puzzle just five days before it was set to expire.
Cracked the puzzle?!! I'm sorry, but this is just stupid. There was no puzzle. The supplementary document provided by Goldman provides a precise specification for how the files are encoded. The only thing an interested person had to do is just apply that specification to a decoding task. Happy for the grad student, though, who has probably doubled his income this year.
The only widespread problem with mysql-server that I can find is the aforementioned upgrade problem. Nobody seems to be having problems with fresh installs, as I would expect.
I happen to be running 16.04 right now, so just to satisfy my curiosity...

So, works for me. As you said YMMV, but quirky system-dependent issues are difficult to debug. I'm not so quick to blame Canonical for a package that passes all
This is not the same problem. His configuration file is fine. Not sure what the problem is in this case, but plenty of people install mysql-server 5.7 on fresh 16.04 without encountering it. So suffice it to say it is probably something weird to do with his particular circumstances, maybe the slightly odd Microsoft Azure configuration. Weird stuff happens in VMs sometimes, especially on cloud services.
FWIW, I don't agree with the sibling poster. I think companies, like Canonical, are best served by supporting their ecosystem as best they can, including for non-paying users, but they can't support every combination of every package. Nobody does that. If you were having this problem installing on Windows, would Microsoft provide free support? No.
Whoa, emotional much?
I wasn't finger pointing, just trying to explain your observation (marked as unassigned bugs), and I think it is reasonable. If you don't agree, please explain why instead of attacking with expletives.
The packages are stable. As I tried to explain, and you apparently missed, the problem with mysql-server is due to an upstream change. The software and packaging are not broken. The bug report refers to a problem during a major release upgrade. It was known possible issue that a user might encounter during upgrade reported in the release notes and is recoverable, so not generally something considered to be a show-stopper, by anybody. The problem with libreoffice was experimental functionality that the user enabled and is known to have problems. Solution: don't enable it. Again, not a show-stopper bug.
They are not ancillary systems: they are core functionality
That may be, but a commercial company cannot offer free support for every software package that someone considers "core functionality". Red Hat certainly doesn't. If you are having a problem with a package that is not in the "main" repository, and you haven't purchased a support package, you are left with community support only. This is clearly stated on their website, https://help.ubuntu.com/lts/se....
Sympathize, but...
Your first link is to an issue encountered during a release upgrade. Release upgrades are tricky and nearly impossible to get perfect, especially when the software involved (in this case mysql-server) is complex and had an upstream change that affects configuration settings. There will always be edge cases that fail in these situations, and it is not necessarily worth it to try to fix every edge case as long as it doesn't corrupt data and the user is able to fix the problem manually. In this case, the upstream mysql-server change was noted in the release notes, so users upgrading should have been aware of potential problems going into it. The packaging of mysql-server-5.7 itself is not broken.
In your second link, the problem is an issue with the OpenGL rendering support in libreoffice and is likely hardware/driver dependent. It is not something Canonical is in a position to fix.
Also, both of these packages are in the universe repository and not officially supported by Canonical. So what you are getting from these bug reports is community support, which is why they are unassigned and don't receive much (if any) attention by a Canonical employee. I agree Debian is much better in this regard, but there is only so much a single company with a handful of employees can reasonably do.
Mitt Romney is one of the smartest presidential candidates this nation has ever seen, as well as a fundamentally decent human being. People tore him to bits over offhand comments and talked endlessly about his unforgivable sin of having - 30 years prior - taken his dog on vacation. (One New York Times columnist published no less than 86 columns talking about that incident, which seems like obsessive enough behavior to qualify for institutionalization.)
Agree (I usually ignore Gail's columns because she rarely has anything interesting or useful to say about anything). However, Mitt Romney did it to himself. He may have been smart and decent, but he grew up a privileged life and he was way out of touch with his base. He tried to portray himself as a "man of the people" by going to county fairs and eating corndogs, but it backfired on him. His Republican competitors in the primary did far more damage to him than Obama in the general.
Yes, there are multiple serovars of S. enterica, but you are mostly picking nits. Salmonellosis, of which (para)typhoid fever are particularly severe forms, is caused by S. enterica, which is transmitted via infected food/water. What we call "food poisoning" is just a milder version of salmonellosis that we can often recover from without antibiotics. In the present day, the epidemiological relationship between serovar and fecal contamination of drinking water points to how severe salmonellosis is most commonly spread, but the reservoir for the disease still has to exist, and 500 years ago this could have easily been domesticated animals.
Yeah, for some reason that feature doesn't seem to work in the new Firefox 57...at least not for me. I do remember using that in the older versions though.
Try the down arrow next to the tab bar then. It shows the complete list of open tabs.
No, it's not acceptable to refuse to boot because of such a bad entry.
Why is it acceptable to continue booting even if there is a bad entry and ambiguity as to whether the entry is required or not?
You are biasing your preference on "it has always been this way" rather than a rationale for why that's a good idea. The systemd folks make a good case for why it's a BAD idea, and thus have decided to make boot fail when it can't bring up an essential volume. If you have non-essential volumes in you fstab you need to explicitly specify it. Very simple, straightforward, and not at all unreasonable, as is usually the case when someone brings up a systemd "defect".
Plus, the OT is right, you're beeing hostile just for the fun of it...
I criticized the OP for not reading some basic documentation, and not preparing properly for a system upgrade that he knew would make major changes to the previous userspace. Sorry if you consider that hostile, but in the old Unix days of yore, RTFM was a very common meme, especially here on /.
