I have to say though, having chrome that is virtually indistinguishable from a webpage is a phisher's dream. You also lose 25 years of low-level graphic development in platform toolkits, which likely means losing a lot of performance.
Interesting research but I am not sure how many people actually believe that startups want younger employees because they are more innovative. The more obvious appeals are that they are childless so they can work longer hours, will work for less, and have less experience in business so are less likely to question the dubious strategies of leadership.

The only 24 hour system in the world. That's nothing to sneeze at. Almost no other metro system is even close to the hours NYC pulls. It's sort of unbelievable to me how early metros like Tokyo as just one example close.
The top-voted reply by TillWinter may be excellent but it actually doesn't answer the question posed by the OP. TillWinter's reply is mostly about the "divide-and-conquer" approach to learning. Yes, efficient study habits are good to know but that type of answer can be generically applied to any learning endeavor.

The reddit OP is asking about specific resources that help with intuition. In contrast, many math teaching materials work from an analytical and symbolic approach (e.g. axioms and properties.) Unfortunately, most people can't truly learn intuition that way and they end up in mindless "plug & chug" to pass the test.
Doesn't Debian follow the ESR releases for their stable branches? E.g. when support for ESR 52 ends they'll upgrade stable releases to ESR 59?
See the NeWS PostScript interpreter code I posted in this thread.

NeWS has multiple PostScript threads, which must be able to block and re-start in the middle of parsing PostScript expressions or anything else that might block, so the entire interpreter has a switch statement for dispatching PostScript operators, and any of those operators which might block have "goto" labels so the interpreter can jump back into the middle of the operator when the threads gets switched back in.

The most complicated operator is the PostScript parser itself (the "file_execution" operator), which blocks in many places, and whose C source code was broken out into a .h file with the comment "be charitable and think of this as a procedure call".

This is actually quite similar to how C# and other languages implement co-routines under the hood. It's just written by hand in portable C.

Here's the comment explaining it:

/*
* The PostScript interpreter has a fairly simple basic structure:
*
* while (1) { 1. Pick up an object to interpret 2. Execute it }
*
* Part 1, picking up an object to interpret is handled by the statement that
* starts "switch (es->type)". es points to the top of the execution stack: a
* stack of sources of executable objects. The switch determines what kind of
* thing the object is being fetched from: an array, a string, ...
*
* Part 2, executing an object, is handled by the code that starts with the label
* "execute_top". It does some tests and switches on the type of the object
* being executed.
*
* All of this is complicated by the mechanism for blocking. If the process
* needs to block, say by needing to read a new buffer from a socket or by
* needing to wait for a message, then the interpreter needs to stop working
* on this process and leave information around that lets it restart. This is
* the "restart_state" variable: it is used as the index to a switch statement
* that is executed when the interpreter starts up, so it won't necessarily be
* intering the main loop of the interpreter at the top. There are cleaner
* ways of doing this, but they can't be written in C!

I hate WebExtensions, but Mozilla has at least demonstrated a commitment to improve and expand that API instead of letting it rot like Google has. They seem to be adding essential features to it so I think most of the good extensions will be possible within a few releases.

I still wish they hadn't crammed it down our throats before it was ready, though. Jetpack extensions worked fine.

> In 1961, as a project manager at NASA, Taylor directed funding to computer scientist Douglas Engelbart, who used the money, in part, to invent the computer mouse. Five years later, at Arpa (now Darpa), Taylor kick-started the internet when he convinced his boss to invest $500,000 of taxpayer money to build a computer network.

So they are giving him credit for everything Engelbart did? I wasn't there but sounds fishy.

> most "entrepreneurs" are not making new things, but finding new ways for others to advertise existing things

What a bizarrely reductionist lens through which to view Snapchat and I guess consumer apps in general — Snapchat is not it's business model (or lack thereof).

Snapchat clearly made a "new thing". It's just looking to an existing business model to monetize that new thing.
This is one thing I just do not understand about many of my countrymen. So often I seem to read about wanton destruction of precious places such as buildings, forest and so on. Some of the destroyers are demonstrably ignorant/moronic, but the worst are the intelligent but sociopathic cynics that wilfully destroy, almost always in the hunt for profit. Ugh. For example a property owner near me destroyed some greatly loved ancient woodland in defiance of legal protections on the woodland. His response to legal action is to sell the woodland - if there were any justice he would be forced to reforest it, and fined half his fortune or something equally fierce. We don't deserve to have nice things around when we let these people thrive.
There is speculation on every currency out there, and virtually all other assets as well. Speculation is unquestionably a good thing.
Why "9585.5", is that a particular unicode character? That only displays squares on my terminal. I've tried to replace this with 205.5 like in the example but that would only display Î or Í.

“Wall clock comparison. Instead of looking at the raw number of states seen, one can argue that the most important metric to look at is the wall clock time: how long (in number of seconds) does it take to solve a given problem? This quantity ultimately dictates the achievable speed of iteration for a researcher. Since ES requires negligible communication between workers, we were able to solve one of the hardest MuJoCo tasks (a 3D humanoid) using 1,440 CPUs across 80 machines in only 10 minutes. As a comparison, in a typical setting 32 A3C workers on one machine would solve this task in about 10 hours.”

I used to believe this too, but not anymore. High transactions fees and slow times are a problem, but increasing the blocksize is not the answer. BTC can currently process 7 tx/second with 1mb blocks. If you double the block size, you get to 14 tx/s, it scales linearly. PayPal processes ~150 tx/s, Visa processes ~5000 tx/s, and can burst up to 50k tx/s. This is orders of magnitude off, and would require scaling blocks up to 1GB. By setting the precedent that increasing blocksize is the answer to slow transactions, you open the door to a future where only a very limited number of powerful entities can afford to run a full node, which brings you right back to a centralized currency. In order to scale BTC, it basically needs to move to off-chain transactions or some other new tech. The devs know this, they want fast transactions too, but they don't want to risk centralization to get there.

> they can always lower it later

I don't think this is true. Once you have blocks on the chain greater than 1mb, those blocks must be valid forever. That means protocol must support new blocksize forever.
From one of the comments:

>"Professional heavy math people are those who said in the 60s that the perceptron's limitations proved all AI was impossible. And in the 90s that one hidden layer was all you needed, deep learning was useless."

Can anyone provide the citations for this? I was aware of the latter but not the first one. You can find people still repeating the one layer stuff up to a few years ago just by reading stackexchange.
32-bit PPC was recently dropped from Ubuntu (and Debian IIRC).
Verbose, unwieldy, harder to read by humans (especially without syntax highlighting) in terms of picking out key data. More unwieldy to write in most languages as well (most now have libraries that will convert a dictionary structure to [or from] JSON in a single call, while XML often still needs to be assembled element by element).

I think it would be an exaggeration to say that there's anything "wrong" with XML, but there's a reason JSON has by far overtaken it outside of "enterprise" applications.

That said, in some ways XML is preferable for standards - particularly in that there's a standard way to publish a document type specification, and widely available tools for validating a document against such specifications. The somewhat experimental equivalents for JSON haven't really ever caught on.
Honestly, I feel the opposite. After spending 24 hours sitting and disconnected from the ground world, I love to have empty chat with some local to know how things are going around there.
Right, but stocks weren't invented and sold to the digital community as a currency.

Is that no longer a thing? Does the cryptocurrency community acknowledge that their product is just a big gambling machine requiring the energy a medium country?

I recently was listening to a podcast (Sam Harris maybe?) where they were talking about the possibility of super intelligent AI being set to a complex task... but then finds itself spending some huge amount of resources churning out paperclips because of some erroneous assumptions about their value to solution.

If we're the super intelligent AI designed by some other "real" intelligence for a purpose, I'd say cryptocurrency is our paperclip moment.
9585 is ╱ 9586 is ╲ (both mentioned elsewhere in the thread by their hex equivalents 2571 and 2572)

Try a different terminal maybe? Works in xterm, xfce, etc, for me. Also, I have LANG set to en_US.UTF-8

The ".5" is because Perl's chr() will convert it to an int by chopping off the decimal portion. rand() returns a floating point number between 0 and 1. That's very similar to what the BASIC program is doing.
Ah, come on. It's not like consumers are going to insert their sims into this device anyway.
FYI, the JavaScript part doesn't start until 3:45-- everything up to that point is just the general history of the internet. I would have skipped there if I'd known, hopefully this helps someone else.
Currently getting my Masters in AI. I'll be honest, I can understand the concepts when presented to me, but the mathematical proofs are beyond me. I've learned to be ok with that. There's just not enough time in a 2 year program to teach myself the underlying vagaries of everything I encounter.

This article leaves more questions than it answers.

Is top 5% of patents really a good measure of scientist productivity as opposed to published articles or research awards?

Is outmigration more relevant than absolute residency numbers? If "top scientists" choose to start their career in a high tax state and don't move, they will not show up in this study.

What percent of this rather arbitrary group are professors, working at large corporations, or some other affiliation?

What is the effect of outliers? No sample size is given and the individual tax rate effect doesn't look very robust in the scatterplots. Does that fact that a large amount of patent law gets set in Eastern Texas influence this more than taxes?

Even for the corporate tax rate effect that does look like a positive correlation, the effect could be due to one or a few large organizations moving their R&D department.

This just seems like some half baked regressions that aren't seriously trying to understand the issue.
Yes. Current stable did not have Firefox ESR 52 when current stable was released, but it has it now.

Debian is providing Firefox ESR 52 even in oldstable (check security upgrades) https://tracker.debian.org/pkg/firefox-esr
This is soochi advertising disguised as question. Can you add the company name to the title like in previous submissions? (e.g. https://news.ycombinator.com/item?id=15621579)
Can't you just increase blocksize to 2-4 megabytes for now until a more scalable long term solution comes into play (segwit)? Sounds like a "best of both worlds" solution.
There are other options. It took me a bit of clicking around to find the pricing information: https://new.shoutem.com/pricing/
Fair enough -- my view may be too reductionist. Still, it would be refreshing to see something based on a business model other than "surveil and/or capture attention, then sell ads."
I suppose, continuing this thought experiment, the generic game engine behind the AI-generated game would be the AI generating games.
I don't see how this would reduce complexity. If you don't need to scale, postgre still better enforces correctness and uses almost no resources. When you do need to scale, you WILL need to switch to postgre. Postgre is also dead simple to install and use for the "simple personal blog" use-cases. The enourmous technical debt you're taking on to reduce the one time installation by 2-3 commands and a slightly quicker download is not worth it.

>'ve only bought a few things from Alibaba over the years, but most of them have turned out to be either faulty or a typical case of 'chinese manufacturer disappointment' which has led me to being reluctant to buy anything larger/more expensive. When I was in Marrakech a couple of years ago, the guy who owned the riad we stayed in referred to many things in the souks as being "China quality", and I guess that's the problem.

Which doesn't mean much ("China quality" that is) since iPhones are also made in China -- as are expensive clothes for the likes of Armani and co and tons of other high-end stuff. And of course lots of Chinese designed and made products that are of high quality.

Of course tons of cheap stuff is made there too -- almost all the world's manufacturing of cheapo stuff. Heck, almost anything you can get on a place like Walmart is probably made in China too, but sold for 2-5 times as much as in Chinese sites.

If someone buys some $80 "laptop" off of Alibaba, or some "leather jacket" for $30, or some no-brand el-cheapo "camera drone", of course they're gonna get subpar quality. If an offer looks too good to be true, it probably ain't, and if there are no reviews (on third party sites) or nobody knows the brand name, well, those things don't point to getting a good buying experience.
I like the comment that likens this sort of deeply-linked knowledge to a DAG. In my own (limited) experience, once I’ve mentally found the DAG where every node either references some other node or baseline knowledge, the learning task almost immediately switches from daunting to routine. Just work on understanding each node in the dependency chain until you get to the one you seek!
I read /r/BitcoinMarkets. It's more centred around day trading, they are very optimistic about the future (i.e. bullish, "to the moon!"), so take their opinions with salt, but it's a good, up-to-date source of information.

This feels like fundamentally the same problem as the whole big company inertia/innovator's dilemma situation. There's value in known-entities, but also a lot of value in trying to reinvent the wheel now and again.

Another problem is it doesn't leave as much room for people to learn from mistakes as companies grow larger and larger. You need wiggle room to get dirty for that to happen.

No Xlib for sure, since it should work on Wayland. I think GTK isn't a good choice for that purpose.

For some reason I'm fascinated by anything subterranean. The Great County Adit is quite an incredible feat, the world's largest drainage adit, started in the 1700s: https://en.wikipedia.org/wiki/Great_County_Adit

Yeah except for counters.

Those god forsaken counters.

You can't just say five pencils. You have to say

5 long thin object even-numbers-4-and-under-and-odd-numbers-5-and-over-counter pencil

Go hon enpitsu

The pattern for which is

Pon
Hon
Bon
Hon
Hon
Pon

Hon
Pon etc.

They can't simply say the number of clouds the same way they say the number of machine presses. Or count small animals the same way they count apples. Or demigods the same way they count flat objects.

Small round objects and military brigades would obviously be counted the same way though. Obviously.

There's also a unique counter specifically for armed naval vessels and slices of fish on top of balls of rice.

And one just for straw mats.

And one for graves, CPUs, wreaths, and dams.

And while small animals and arthropods have one counter, and large animals have another counter, you count butterflies using the counter for large animals.

Oh and the first 10, 14th, 20th and 24th days of the month essentially have unique names.

I knew a native Japanese guy who spent 4 years mostly away from Japan, and he started to have trouble remembering the days of the month.
The same holds true for Amazon. Read the horror stories. So it's not like it's unique to aliexpress.
> don't all the 1's still fundamentally change the equality since they change the units?

Not more than changing unities from meters to feet, or kg to pounds.

When two unities are related by a constant, they are measuring the same thing.
The alternative would be maintaining many toolkit backends. We already see how well that worked out. Qt backend wasn't maintained in a while, and fell into bit rot. That basically prevents Firefox from being used Plasma Mobile and the like. Having HTML backend is better than having none at all.

Learning all the advanced math within a few years is a hopeless endeavour. It would take decades of hard work because there is so much out there, and we need to know all of it if you want to make progress (e.g. pull out a fancy-name theorem out of nowhere to solve some practical problem).

I find a better approach is to focus on a few basic ideas you need specifically for your work and digging deep in there. Nobody can be expert-level in everything, but you can be expert level in your specific domain of research.

Also for ML stuff, it's hard to overemphasize the importance of understanding linear algebra really well. Here is a excerpt of a book I wrote on LA which should get you started on learning this fascinating swiss-army-knife-like subject: https://minireference.com/static/excerpts/noBSguide2LA_previ...
BigQuery would probably be the easiest, low maintenance approach. Normally I would leverage the Hadoop ecosystem for this type of ad-tech/analytics problem, but I am not 100% certain of your use case, budget, etc. Providing clients read-only SQL access would be much better than a REST API.
You read the onsite and offsite reviews, just like with every other store?
I think an important lesson for any grad student is to learn to read through the bullshit in papers and try and understand what the authors actually did.

It helps a lot that in CS you can often see the code that the authors published along with the paper. Just staring at formulae doesn't mean much, because for all you know the author just hammed up the equations to get their paper into a top conference. That's not to say that the equations are excessive, or the authors are being misleading, but I think there is definitely an expectation in some fields that putting equations in makes your paper look clever even if they're broadly unecessary.

It's also wildly different depending on the field. If you look at variational methods in computer vision, images are [continuous] mappings from some domain onto the reals (I : Ω->R3 for colour). Does that change the fact that an image in memory is just a bunch of numbers in a grid? Not really, but it's bloody confusing the first time you see it.

This doesn't help with understanding the maths, but at some point you have to give up and say "This guy proved it, and someone else peer reviewed it, so I can use it to solve my problem". It's perfectly OK to stand on other people's work and still make creative contributions to your field, that's the point of research.
Yeah, I hope this will be usable in Plasma Mobile.
People don't make decisions in a vacuum. Scientists also care about their children learning STEM, so they will want to live in places with good schools. It's partially why they stay in Minnesota over Wisconsin, Massachusetts over New Hampshire, and so on.
