I wonder how this would work out legally if someone accepted this offer and then was sick and unable to work during the window it pertained to.

Consider, maybe, that the worker has a migraine and feels like it'd be unsafe for them to be driving.
The in-frame patch panel (aka junction box) may require pulling a few other things off the bike like the cranks (if access is through the BB cluster) which is often only a few minutes work when you have the correct tools.

Which leads to the fact that many bike tools are incredibly specific, and require updating almost more often than the parts they are meant to be used with. Insert old joke about standards and having so many to choose from - but that's an issue that stands to the side of electronic against mechanical parts.
Makes complete sense! Your English skills and also answering
my question with something measurable are impeccable. I hope you write code like the way you answered my question. Would be one readable piece of code.
As to [1]: Yes, I was not honest in the sense that non-standard SVD implementations for generating your PMIs will scale with the square of |V|, not the cube. But as I will go on to show, that is not good enough to make count-based approaches competitive to predictive ones.

Re. [2], these measurements by Radim have several issues; First, word2vec is a poor implementation, CPU-usage wise, as can be seen by profiling word2vec (fastText is much better at using your CPUs). Second, even Radim states there that his SVD-based results are significantly poorer than the w2v embeddings ("the quality of both SPPMI and SPPMI-SVD models is atrocious"). Third, Radim's conclusion there is: "TL;DR: the word2vec implementation is still fine and state-of-the-art, you can continue using it :-)".

So I don't really get your points. Instead of referencing websites and blogs, lets take a deeper look at a "proponent" for count-based methods, in a peer-reviewed setting. In Goldberg et al.'s SPPMI model [1,2] they use truncated SVD. (FYI, that proposed model, SPPMI, is what got used in Radim's blog above.) So even if you wanted use SPPMI instead of the sub-optimal SVD (alone), you would first have to find a really good implementation of that, i.e., something that is competitive to fastTest. Also note that Goldberg only used 2 word-windows for SGNS in most comparisons, which makes the results for neural embeddings a bit dubious. You would typically use 5-10, and as shown in Table 5 of [2], SGNS is pretty much the winner on all cases as it "approaches" 10-word window. Next, I would only trust Hill's SimLex as proper evaluation targets for word similarity - simply look at the raw data of the various evaluation datasets yourself and read Hill's explanations why he created SimLex, and I am sure you will agree. "Coincidentally", it also is - by a huge margin - the most difficult dataset to get right (i.e., all approaches perform worst on SimLex). However, SGNS nearly always outperforms SVD/SSPMI on precisely that set. Finally, even Omar et al. had to conclude: "Applying the traditional count-based methods to this setting [=large-scale corpora] proved technically challenging, as they consumed too much memory to be efficiently manipulated." So even if they "wanted" to conclude that SVD is just as good as neural embeddings, their own results (Table 5) and this statment lead us to a clearly different conclusion: If you use enough window size, you are better off with neural embeddings, particularly for large corpora. And this work only compares W2V & GloVe to SVD & SPPMI, while fastText in turn works a lot better than "vanilla" SGNS and GloVe. What I do agree with is that properly tuning neural embeddings is a bit of a black art, much like anything with the "neural" tag on it...

QED; This article is horseradish. Neural embeddings work significantly better than SVD, and SVD is significantly harder to scale to large corpora. Even if you use SPPMI or other tricks.

I just think that's breaking-expectations-bias: "Man bites dog" stories get more attention than "Dog bites man", because the community expects the latter and doesn't see it as newsworthy.

No, its not. (Its true that it contains content that is to the right of what you'd usually see in the WSJ, but it also contains content very far to the left of what you'd find in the WSJ; on balance, it is very much not to the right of the WSJ, though it might well be to the libertarian side of the WSJ.)
Not every project is deserving of funding. Grants provide at least one filter, and at least in my experience have some correlation to merit. There's just not enough money, spreading it out doesn't help.

Attaching funding to academic politics sounds like the death of innovation, but that may be an exaggeration.
If the CFTC writes a report about, say, Corn Futures, they talk about what the rules are, and what you can do if you get scammed because a bad actor violates those rules. The CFTC might say, "you have the right to appeal a decision" yada yada.

>But that suggest prices are set by the available cash flow. Which means without other factors if we just lower everyone’s wages to zero everything will be free. Obviously this isn’t the case.

Prices can rise above cost, as long as someone will keep paying for it, But prices can only drop until the seller loses their incentive to sell, at which point the product/service will be withdrawn from sale.

It is amazing how different the regions of Maine are. I'm in NW Maine, which isn't like it is up in the county, nor the mid coast, down east, southern, central, or even western.

I'm more Jackman and less Bethel, but the village is more Bethel and less Jackman. It used to be a bit more Bethel, but the ski slope needed money to replace the lifts and they are now shut down.

So, just in this one State, it is a lot of variation.

Curious: did unionization reduce the # of graduate students UC Berkeley was able to allow in?

This has been a common criticism I've heard, and would have potential ramifications on the long-term research pipeline if it were true + spread nationally.
I occasionally design fabric patterns, so the pages on applying graphics to the tessellations are interesting to me. What I'd like to end up with is a generalised script for creating repeating patterns from a small set of images (e.g. dinosaur outlines for kids' clothing, or flowers for haberdashery). If I could be procedurally generating a variety of designs based on different tessellations, it would greatly increase my potential output.
Any idea what the criteria were? Was it by department? Degree status? Teaching vs fellowship status?

In higher ED this seems like a long time coming.

Grad students essentially work as slaves for the Uni's & professors with triple-duty in lab time for professor + teaching + self-research.

Their reward comes in notoriety & bi-lines on research that helps them become professors in their own right in higher ed.

The cost is minimized rights to IP they've been crucial in inventing, outrageously low wages, and an average of $100k (1) in debt.

The brutality is sold as a right of passage, but the reality is the incentives are completely out of whack - uni's have an inverse incentive to admit Phd / grad students to benefit from the wage-slave / revenue generating aspect.

And it shows in the data - there are now a "glut" of PhD's that are far outpacing the very limited # of academic positions.

The system needs fixing and if unionization exerts some pressure on correcting the macro problem I am all for it.

I'm excited about this. I had the advantage of working full-time while in grad school, and my company paid for most of it, but I missed out on being a TA and getting classroom experience.

I watched a lot of fellow grad students struggle, constantly worrying about grants and funding. Some just took loans, others rushing so they could get through before their fellowships ended.

Meanwhile you watch new buildings, dorms and student centers go up as undergrad tuition goes up. Most professors I know who are my age are all adjunct or part time, but it's their full time gig.

Adjuncts positions were meant for professionals in the field who wanted to teach a class or two. The position is really being abused to keep from paying hard working professors a full-time wage and keeping them from a tenure track.

So where the hell is all the money going. Yes there are cuts, but we still see new buildings and programs. I realize these are different budgets a lot of times, but it's still getting really ridiculous.

If universities want to do something real, they need to stop worrying about unions and start tackling the student debt situation. They draw students deeper into debt than they've ever been in history to fund their institutions. You can no longer work a part time job and pay for many state schools. And what if those kids graduate and decide they really hate engineering or business or whatever they got. Now they feel like slaves, working jobs they hate to pay off that debt.

We desperately need student debt forgiveness. It has to happen. The bubble needs to burst, the system needs to collapse and schools need to scrap and rebuild programs that are affordable, that work and that are significantly better and different than their shitty for profit counterparts, which they're becoming more like everyday.
"Confining scientific critique to scientific venues"

When you take your BS "studies" and sell it to the audience at TED and then the wider internet, go on corporate speaking tours, sign book deals to promote your "science", and try to affect public policy, you are open to criticism from anyone who sees through your shoddy methodology and wants to correct the record.
Given the pyramid scheme nature of graduate programs, this may be a positive outcome.

>"But migrations --" well, Arc makes it super easy to define a "template", which is just a set of fields, and each field is whatever you want them to be.

That's... just a struct or a map in any other language. Convenient but not necessarily a point in Arc's favor per se.

>So yes, theoretically if you wanted to rename "kids" to "children", you're gonna have to process all the old data. But 1. then don't do that, and 2. even still, it's not hard to do that anyway.

It's still an argument against using flat-files. Updating a site with a proper database isn't typically tied to disk read/write speeds - at best renaming "kids" to "children" means changing a field in a model and maybe a template - and that's a fixed amount of work regardless of the number of records you have.

>My main focus has been updating Arc to run on JS, and to add keyword arguments. That way you'll be able to use the whole JS ecosystem too.

You mean Node/NPM on the backend? That might be interesting. I'm not familiar enough with Arc to know (I've only played with Anarki a bit, but I have too many random projects on my plate as it is) but does it even have dependency management?
Those sound like good ideas, though something that big would still have an issue fitting on something other than a recumbent or cargo bikes (often see lights that size already on those now).
IANAL, but it's similar to how cabs, barbers, strippers, and other contractors operate.
Same experience here in SF.
Most users simply don't care whether a framework or hand customized code is used anywhere in the stack. This includes the front end all the way down to the assembler shoveling bits through a processor.

Why should somebody who is technically proficient or even highly skilled in developing on the backend bother with becoming equally skilled enough on the frontend to not "need" these frameworks? Especially when it matters very little.
Have no idea why you're being downvoted. I think your point is salient and under appreciated. Certainly from my own experiences it's easy to get caught up in the product and the tech, and not focus enough on the biz side of things. Ie. Sales and Marketing.

Basically I'm in complete agreement with you, and feel this is a hard learned lesson.

Ugh, that's a really disturbing strategy. Is this a common tactic for freemium games? I've seen "daily login rewards" type things which give you an incentive to play daily, but I've never before seen something that is an actual punishment for not playing.

I suppose "lingots" don't really have a monetary value, but imagine this tactic done in a game where the currency is worth some amount of actual money.

Yes,

Recently I read about Postgres 10 release. Almost all of the features of that are available in MongoDB too.

4 or 5 years ago, MongoDB was bad. But nowsaday the landscape was changed, and I would say MongoDB is quite decent to work with now. It's the easiest database to manage, compare with MySQl, PostgreSQL, ElasticSearch.
Not obviously, though most people I knew were in reasonably well funded departments/programs, and at any rate they were unionized well before I got there, so I wasn't around to observe any changes.

For what it's worth, I'm not convinced that the research pipeline isn't already overfull. The tenure track shouldn't be the goal of all incoming graduate students, but I think the increasing length of postdoc positions, the massive oversupply of adjunct professors, and historically low rates of grant funding are hints that there's something wrong.
The article is also referring to a very small group of herbs.

If you have to use both brakes to stop your bike then your brakes are too weak.
I was thinking about that and it could just attach to the frame and then use something like an aluminum pole to hold it out over the rear tire. It'd be light and adjustable.

It'd look dorky, but it might save lives. I doubt it would add much weight or reduce aerodynamics very much, at least not as regular rider speeds. It's not like they would use it while racing.

It's funny that the liberal ivory tower academics in charge don't want unions...... Oh the... I'd say irony but it is really hypocrisy.
Not a professional bike mechanic (I build bikes as a hobby) but in general your front brake should be set up to be powerful enough on its own. This requires clean rims, and clean, non-worn, non-hardened brake pads.

"As in, I would prattle on and converse in Spanish - fluently. Except, at the time, I wasn't actually fluent."

My dreams frequently claim I am a master composer, and that this tune is wonderful, or that I've written a really clever joke, or that they've told me something important. None of the things I've ever dragged up to the waking world have ever even remotely panned out as the dream promised. (If I may anthropomorphize for convenience.)

I've come to the conclusion that that is the dream, in some sense. You dream that you were fluent in Spanish, but not just that you abstractly believed in it but that you had the experience. But what language were you speaking? Nothing. Nothing comprehensible, and possibly literally nothing at all; simply the empty experience of fluency without any concrete referent.

Which makes the Dunning-Kruger effect more comprehensible, if it is possible to experience the feeling of "competence" divorced from almost anything concrete. Dunning-Kruger IMHO happens when the competence is firing and the person in question has no counterbalancing reasons to suppress it. So one of the keys of true competence is to be sure to eschew that feeling, in favor of seeking out the ways in which you are not competent. That is another way of looking at "deliberative practice", where you are always practicing just a wee bit beyond your capability. If you don't do that, it's too easy to rest on your laurels and feel soooper confident and awesome that you've really licked this Twinkle Twinkle Little Star tune, so now you really know what you're doing.
Switching costs for consumers is low. There is really no difference where I live between Uber and Lyft, and I could see another two or three competitors doing the exact same thing.

Another industry that has low switching costs for transportation are the airlines. They had to implement rewards programs to keep customers loyal, and that still hasn't stopped the race to the bottom in terms of price.
To pile on to the no non-sense, it also means it doesn't try to do social networking and share my information publicly by default.
That makes sense but if people are trying to level set it's worth knowing that WeWork is 0% of the way towards monetizing its subsidized tenant base this way. There's a "WeWork Services Store", sure, but there's nothing remotely interesting in it.
Facebook security boss says its corporate network is run “like a college campus”
Something I often see overlooked in critiques of the wework buildings:

Their offices are vastly different in renter demographics, I have found after working from different offices on an ongoing basis. Even within the same city you will find a vastly different feel from building to building. Boston, New York, and San Francisco have multiple buildings that are quieter and noisier, some with mostly mature companies and some with all single person co-working renters.

It's not perfect, but as a company with up to 10 people or a need to have distributed office space... I'm a huge fan over the last couple years.
