Wonder if the finance roles of quants and quant devs will spread to other industries. Quant devs are math heavy programmers that might not do original research but still can understand/calibrate/implement the models the pure quants produce. Ie given an abstract paper with a shiny model (or a hacked together spreadsheet...) the qdev might need to analyze what monte Carlo error correction strategies are relevant for the problem or how a certain market's peculiarities might influence calibrations etc.

Also, quant devs are heavily involved in building the calculation engines that invokes the models. These engines handles real-time dataflow and calibrations etc and are often highly non-trivial.

My guess is that that type of role is relevant in a data science context. This is much more than data cleansing and piping data between databases.
Great product idea. At work we use Skype for business and it's a disaster - especially bad is it seemingly randomly says 'your device is causing poor audio quality' and mutes you. The only way to recover is to dial out and in. Before that it was the AT&T solution - such an ugly application with poor usability. If Amazon really polish this product and provide a great user experience and quality they could pick up a lot of business.

Edit: there's a problem here. Skype for business allows up to 250 participants. The AT&T solution (webex maybe) allows, I think, an unlimited number. Amazon Chime has a limit of 250 people. This wouldn't cut it for presentations in large companies e.g. announcement of annual results or divisional virtual 'town hall'
Or even put their Screenhero acquisition to good use and finally roll out screen-sharing.
Have you looked at Zoom(zoom.us)? We have been using it for a while now and it seems to work very well for us.
It's incredibe the infrastructure these things have. A plane is so utterly dependent on having everything ready where it lands, which is why this emergency landing probably throws everything into disarray.

Strangely like an F1 car where they don't have a starter on the plane, they need an assist to get going.
Yes, agreed. It is great — use it where I work (10k employees) and it was such a relief over all the conferencing solutions we tried (my team was a guinea pig for several).

The coolest thing is that the company rolled out hangouts in a weekend to 100% of the conference rooms, replacing all projectors in the process. It completely democratized remote work and remote offices since people are using Hangout by default.
You're right in that 99% of them are complete garbage. However I was pleasantly surprised when my company switched to Zoom[1]. A company I had never heard of before. In terms of call quality I've never experienced anything better. Beyond that their mobile experience is almost better in terms of raw features than their desktop app (which is still very good in its own right).

I sloshed a bit of coffee on my keyboard, first such fck-up in over fifteen years. They want $620 to rub wipe the coffee off and put the keys back in place (they sent a photo). I'm praying that tomorrow morning I can talk them into mailing it back to uncleaned but still disassembled and let me pop them back in place....
Zoom seems to be a lot better for pricing.

At a company of 12 people, our GoToMeeting bill was $15,000/yr.

But uhh, call-in rates of 1c/min/participant? That's going to add up. We would regularly have meetings of two hour duration (programming, planning) with up to six-eight attending is a $10 meeting in itself. Chicken feed compared to salaries but I could easily see pricing of up to $1k/mo with this.

Shame.
Or uses stripe which hides your real card number from the merchant. The annoyance of adding a card is one thing but fear of an app developer getting hacked and exposing your card doesn't strike me as a very strong reason.
> Using an RDBMS as a work queue is an anti-pattern

I don't want to appear too ignorant but why? I hear many claims of this but few explanations. The best I've heard is something about not being able to handle the load but I don't really buy that unless you don't need persistence/integrity.
Yes we've used full text search for quite some time for one of our products, it's great, we really haven't had any issues performance or otherwise with it. For one of our other products we index data from PostgreSQL / PostGIS into elasticsearch and that's also good, in other ways.

Correct. But the signature doesn't necessarily need to be per-file upload, so I have it embedded in JS. For my use case, saving the extra network hop is worthwhile.
It's definitely an organizational "SPoF" a-la Lavabit in that govts can lean on it, attempt to squash it, try to hack it, etc., whereas distributed solutions like i2p and BitTorrent are harder to strangle.

In a dark room I find the minimum brightness much too bright. Weird feature to wish for, but I think they need to crank the minimum brightness down by at least 25%.
Thinner implies a better ratio of surface area to volume for dissipating heat. Though, I suppose a laptop could be thicker by including empty space with fans and airflow to exhaust the heat out the sides rather than conducting it through the surfaces touched by users.
This was my first thought on this site too, on Chrome on macOS - I closed the website in frustration, it made the reading experience awful.
The Internet had immediate and obvious applications, it just took time for those to become fully realized. It was also a massive effort involving entire industries, not one dinky little company hacking away on some idea in obscurity.

There were companies making internet killers, don't kid yourself, and they're all dead. Prodigy. Compuserve. People don't even know what they are.

Likewise the mobile phone had immediate and tangible benefits, but it took a while for the devices to get small enough and cost-effective enough for everyone to be able to afford them. They had immediate appeal. This was also a push done by an entire industry.

It's extremely rare that a singular company ever succeeds on this scale.
> Does WhatsApp have reproducible builds yet?

WhatsApp isn't even open source, so no, it doesn't have reproducible builds. (Signal is open source and does have reproducible builds).

> Do we know that the app isn't storing the keys somewhere else?

No, but WhatsApp is still strictly better than either email or SMS. Even if you don't trust Facebook, that still only leaves three parties that can compromise the integrity of messages (you, the recipient, and Facebook), as opposed to the uncountable number of parties that can passively observe email or SMS in transit.

Decimal numbers along with zero ٠١٢٣٤٥٦٧٨٩ were invented in India. The arabs used them until early days of Islam. Then due to fraud issues with the zero, being just a dot that can easily be overwritten to anything else, the arabs set to invent their own symbols. The new symbol is angles based, zero being a circle has no angles, 1 has a single angle and so on ...
The symbols 0123456789 is yet to be adopted by many Arab countries because it was invented post writings of Quran, where it uses the original Hindi symbols.

Four Major Breakthroughs Made in Chinese Power Transformer Component
The power transformer is an essential equipment for the power transmission and transformation system and its faults have a major impact on power grid operation. There is a variety of component breakdowns and causes for breakdowns are also complicated. The transformer component breakdown accounts for 20%-45% of total breakdowns,which remains a prominent problem.

I really do not like conference systems which do not work on Linux. Not everybody is using a Mac or Windows. Microsoft is also ignoring Skype and Skype for Business on Linux. This is all crap.

The one thing that has most frustrated me is PHP's array syntax.
I'm still always amazed Apple doesn't offer better support packages for professional users, given that they clearly are in the premium market. Something like "we'll swap your SSD in a loaner device if we can't fix it immediately" sounds like it wouldn't be too expensive to implement.

We had it at my old company and it was garbage. Super frustrating to join meetings (type your automatically generated, super long meeting name on a tiny keyboard), random crashes freezes and relatively poor video quality. Another super annoying thing was screensharing had an extremely low bitrate. It was so bad that it was pretty pretty useless to demo any nice UI features or animations. The framerate was 2-5 fps.

+1 to this.

We're across 24 hours of time zones and conduct a majority of internal and external meetings over video conference. We've pretty much tried them all and Zoom has been the best.

Availing Premedical Courses
Secular??
I remember being in school playing with Google Earth. Hype back then was a bit different but I recall everyone who laid eyes on it was blown away.

Another great google product that I think is actually under hyped is Google translate. I was in Kiev and ordered off a menu by looking st it through my smartphone. Sitting at a table with 6 engineers and everyone was floored. If you haven't tried it I highly recommend it.
That's a fair point - though I think you could debate whether or not the current 48-bit address space of x86-64 is part of the architecture or just an implementation detail. But in the end I don't really think it matters which you consider it (And I'd be happy to consider it to be either). All that said, you're completely right that with current x86-64, there are 64-bit values that could never be a valid address.
If you look again, I didn't mention that name at all. The only relation is that, after the changes in London and Washington, outside interference will now not only be coming from Moscow, and they are capable of exerting far more refined influence than Moscow's online troll army and funding of anti EU activists.
Another non-team sport that has good problem solving aspects but on a faster pace is trail running. You don't get the same thinking through a route you might have with rock climbing, but leaping over rocks and ruts requires some quick subconscious analysis and careful pacing that can be quite exhilarating.
List of operating system for raspberry pi
I agree. And thinness to me is more about minimalism than anything else. And that I laude Apple for.
I find that history interesting.

What absurd path? I honestly don't understand what you are getting at.
Primarily, because it's hard to get right. Of course it can be done well, or correctly (and as The Fine Article points out, adding SKIP LOCKED to SELECT ... FOR UPDATE will go a long way towards that). But most people do them terribly.

As just one example, from a previous job: they were using SQL Alchemy in the code that interacted with the work queue, but somehow didn't realize that the DBAPI being implicitly transactional meant they'd need to manage transaction-state themselves. Consequently, they never released the implicitly opened transactions that every poll for new work created. No-one thought it was strange that the work queue system needed to be shut down weekly, so that a VACUUM FULL could reclaim the gibibytes of space that were wasted because the db couldn't clean up tuples (row version) that still appeared live to stale, abandoned transactions. Until I was all, "Uh, guys?"

The fix was obvious: disable implicit transactions. But that's just one example, if particularly egregious. I've seen and heard countless more.
Strictly true in the context of "first amendment".

But what I've realised recently is that "free speech" is more than just a legal right conferred by the government, it's a social climate. The climate of free speech is even more important than the government right, because if the climate is lost then people will start demanding that the government abolish the legal right too.

A social climate of free speech means a society in which people are accustomed to hearing things they find disagreeable, and don't flip out every time they do.

It means that although people hypothetically can punish each other for views they find disagreeable by means such as boycotting their businesses or shouting at them when they try to speak, they manage to refrain from doing so in all but the most egregious half a percent of cases, and generally tolerate disagreement.

This is what we're in danger of losing at the moment, and if this is lost then the legal right can't be far behind.
What other languages are you familiar with to compare it too? Because Javascript is in no way well thought out and it doesn't do parallel computing let alone do it right, it's bound to a single core.

This sounds awesome and fast. I'm curious to know:

1) What background did you have at the start?

2) What resources did you find most valuable, and how did you use them? (e.g. did you just get a book per topic, and work through chapter-by-chapter, doing the exercises?)

3) Did you get help from friends/colleages, or were you able to work through all the materials independently?
Thanks for the explanation. I think I might have slightly misunderstood your original comment.
what brand/model is the windows laptop? they are usually worse than mbp in battery life so i'm curious.
Do you know if it will slow charge from a low power usb power source?

If I plug mine into a 2 amp usb A charger it says that it is not charging, but does that mean it is drawing zero watts, or only that it is only drawing 10 watts? It would be nice to charge it overnight if only a phone charger happens to be around, or even just slow down the discharge rate while using the laptop.
Great. So let's just stick our heads in the sand and pretend that politics isn't relevant.

Maybe with previous models, but considering the new MBP SSD storage is soldered in I don't think that would be practical.

Grip and hand fighting are very integral to both combat sports. A sport like Ju Jitsu helps improve not only your grip strength, but foot dexterity and prehensility.

Thinner also (usually) means lighter, and a lot of people prioritize light weight over longer battery life.
My feelings about Indian education are re-affirmed in this article: http://www.thehindu.com/features/metroplus/The-Indian-number...

“Akkangalude Charithram deals with everything about numbers; the science and history of digits, ancient culture and tradition which led to the discovery of the number system, and how the political, social and scientific fabric steered India towards the magic world of numbers.

“This book which shows the history, science and uniqueness of the Indian number system can help instill in students a love for Mathematics. The sad part is, many Indians are still unaware that the decimal system originated around their homeland,” said Paulose Jacob.
Their claim of "a third of the cost of traditional solutions" is an apples and oranges comparison.

The basic and plus pricing options, while cheap, are practically useless with only 2 maximum attendees and the $15/user/month pro plan is hardly "a third of the cost...".

Looks like a great product with an average price point.
This is complete nonsense its entirely impossible to run a large scale conversation without stepping in editorially to some degree. The impartiality criteria you are specifying is probably in fact impossible to define sufficiently in practice while doing so and the fact that people may in fact say nasty things on the internet is an acceptable cost to having a free global communication system.
He is unafraid. He's rich and his livelihood is not threatened. He's got an audience already and being banned from twitter wouldn't affect his livelihood much.

Why is it revenge if passed as a law?

Indeed, recent years by Putin, Erdogan and Obama show that you can pass a lot of things as a law and everybody has to comply. To any kind of insane dung!

Unfortunately, not. Because in my culture, the commonplace handling of problems is not solving them but just piling up and then dying when they topple over.
Zoom is consistently garbage for us. The latency is high, the audio quality is low, and the apps have a really terrible user experience.
The Hidden Costs of Indexes
I've seen almost every solution used internally at Amazon to one degree or another. It's really telling that you get a bunch of highly competent technical people in the room and they still end up fighting with the conferencing software and waste a bunch of time in the meeting trying to get everyone connected.

I'm really not surprised they built their own in the end. It's a clear pain point for companies.

That said, my current employers (not Amazon) have been using Zoom (zoom.us) and it seems to be really quite good. I've had almost no problems with it at all.
Honest question what do you enjoy about the super slim phone? In the last years have you seen any phone thats too thick to hold or hard to put in pocket or just about don't fit in any place? Why slimmer, I honestly don't understand since it only makes it more slippery, harder to grip, more fragile. I don't see any use for further slimming than making a fashion statement or a notch for the marketing team.

I can understand if someone says they want even lighter.

Analogies are often useful tools to explicate things by relating them to already understood concepts but utterly useless to make useful proofs or arguments because it oversimplifies to the point of uselessness and misses the ways things differ.

These arguments via analogy are so worthless, so without substance that it is usually a massive waste of time to try to explain to the originator the ways in which the analogy differs from reality so I will simply ask you to come back with an argument based on reality instead.
We need a small size intelligent being in order hold the puppy carefully and place it in a basket or sth like that.
Robots? Could work, but agents are usually designed to do a specific task. For saving a puppy from a deep norrow well, I don't know if there any robot exists. Anyway, we dont need to call this an "engineering problem". It's rather a biology problem.
Scientifically proven that mature animals have instinct to save the youngsters. I would release down a basket with another dog in it. When it reach the bottom, the mature dog will hold the puppy from the neck, and place it into the basket with itself. So I could bring them all the way up. A small size monkey could work to. We may need a very small training for the saver animal tough, to mitigate the risk of loosing both.
