Java is a pretty nice language, it's the Java old-school waterfall java developers that bother me. Our IT development unit is a slow dinosaur waiting to be eaten up but no native competitors.

I've waited months for a bug to be fixed because it "wasn't in the schedule". Theres a kind of "sealed lab" mentality where they hold a bunch of meetings to get stakeholder views, and then disappear for 3-4 months and come back with some 1/2 working software that I could have(and a few times have) knocked out as an alpha in 3-4 weeks.

It's the worst aspects of people being "enterprisey" with people who have no performance or profit pressure so they're able to put out crap and if it's better than nothing the admins accept it.
I don't think I'm at that point. Not only is the birth lottery just another form of wealth disparity, but the economy is not a zero sum game. If we bring in rich and productive people they can create jobs as well as take jobs.
I find comparing situation of Jews in WW2 to the current situation of homosexuals in Russia tasteless.

It's unusual to see a coherent, from-first-principles explanation of a neural network. Especially one that's commercially valuable (i presume) to Totems.

Mildly alarmed to learn I'm only .039 probability male, though - better bloke it up on Instagram.
Depends on the parts of the .net community a lot. There's some really nice parts of the Java/JRE community too so it's not like it a function of the language, its a function of the organizations choosing the languages.

Everyone seems very focused on the tech, but IMHO outcomes are mostly driven by very familiar factors. Here's another perspective on learning online: make it full-time and ramp up social engagement. I operate an online learn-to-code program that parallels a similar in-person program (http://www.hackreactor.com/remote-beta/) and educational outcomes (assessments) are on par between the two.

I'm excited that Microsoft is dedicating some resources toward building a prediction market platform. It joins the space now occupied by Foresight Exchange, SciCast, Inkling Markets, Lumenogic, Predictious, Truthcoin, and similar software platforms. Hopefully Microsoft will build a better product and find more success, though so far it seems like the lack of prediction market uptake seems to be the result of low demand, not low supply.

As a long-time participant in prediction markets, I'll a list of my initial impressions of the Microsoft platform.

(1) I think it's big mistake to mix opinion polls with forecasts. It's quite confusing when one set of questions asks for facts and another set asks for opinions. It's also confusing when one set affects your score and another set does not. I think users would have a better experience if the two categories were totally separated (or if the opinion polls were just axed).

(2) The scoring method they're using is not at all transparent. I suspect it's the logarithmic scoring rule (best for low-volume markets), but the interface doesn't make it clear how the bets relate to the odds. (Look at SciCast.org for one way of doing this.) I understand that the math behind betting can be offputting to new users, but it's also tough to get engagement when new users don't really understand the possible actions or their consequences.

(3) The default bet sizes are awful. 100 points out of a 1,000 point balance means you'll be practically done with the site after 10 bets. Even if your bets are accurate, you can't bet again until they resolve. The SciCast play money market has had significant problems making accurate predictions because of a lack of liquidity for its high-volume users, who also tend to be the most accurate users.

(4) I think I've already run into some bugs. When I vote in polls, it looks like my vote is being assigned to a choice different from the one I voted on.

(5) I thought the design looked nice at first, but there are some usability problems. It's annoying how forecasts with three options require you to click a small button to scroll from side to side. A big part of casual non-algorithmic prediction market participation is quickly scanning over the markets to look for obvious mistakes. Making it hard to scan over the forecasts makes the market harder to use and less accurate.

Anyway, the momentum behind prediction markets has been growing for years. Perhaps in the future more companies will try experimenting with internal markets to predict things like whether projects will finish on time or on budget.

I wish Microsoft success with this new product.

It will go mainstream when the average Joe starts to care. So far, this hasn't happened, and there's no indicating of things getting any better. Circle so far is Coinbase minus the fees minus API minus adoption minus integrations minus large customers minus mobile apps. The only good thing is the lack of fees and the higher weekly limits ($2,500/week of instant buy vs $1,000), which isn't little, but not something that Coinbase cannot meet and beat given they have a lot more volume and ways to internally settle orders vs heavily relying on Bitstamp.

"You’ll not be eaten by computers any more than folks were eaten by electricity 100 years ago."

Although I enjoyed the post and agree with a lot of it, I disagree with comparing coding skills to humans having access to electricity. In think coding today is like writing was 500 years ago.

In the past you would hire a literate person to read your documents, write you letters, and so forth. Today we hire programmers to help us get the most of our computers. I think reading and writing code will be the new way to make the most of computers in the future. It may not necessarily be through the coding tools and languages we have now.

>What that means for you is that your company will most likely be moved to Texas, as is what happened when Vista bought my last company this year.

I'm guessing you worked for ACTIVE Network or Omnitracs. From a PE standpoint it's a great move to cut costs. You can pay less in rent and really save money on salaries through the lower cost of living in Dallas and from many of the employees that will quit because they don't want to move.

Really unfortunate to work for these companies when they are bought and moved though, if you're lucky enough to not get laid off in the first place.
Heard the same from friends - they were sending meat products that were a little on the grey side of import rules across a border. Vacuum packing + bleaching it overnight seems to keep the sniffer dogs away. Whether that works for drugs I can't say though.
I'm agree with you and aware about the fact that the Fibonacci metafunction is not a good example of real metaprogramming (Computing Fibonacci series using tmp has no much sense). I only picked that example because its recursive structure is pretty well known (Is one of the most common first examples used to teach recursion), so fits well to show people how a complex template is instanced, which is the idea of that part of the post. Compare that with using an instance of std::vector, for example. Is a much more realistic example, but people usually doesn't know about the inside of a vector and how it's structured internally. The main objective of these posts is to explain tmp in away that everybody understands it well. When we all are well covered about the basics, we will can get into more complex and realistic cases in depth. That's exactly why more complex examples included in the post, like build_string, are not explained in depth. Are more a proof of concept.

Test kits are cheap, ~$25 on Amazon: http://www.amazon.com/NIK-Drug-Test-Kit-Methamphetamine/dp/B...

The Silk Road (and presumably the darknet markets that followed it) let any user contest the charge and get their money automatically, which they almost certainly would do if they got MDMA that tested badly.

Further, if this happens too many times, the marketplace will just seize the account. Vendor accounts are expensive, so it doesn't make economic sense to sell bad shit.
Sure, but that's really just another form of "cache". Before you hit that, you generally get TLB stress on top of the cache line stress, so you're already hosted.

I have to say though, I've not seen too many cases where paging was caused by bloated object code size (lots of cases where it was caused by brutal bloat due to just outright bad code).

There was a time a couple of decades ago where it was a common issue with C++, but since then RAM has gotten a lot cheaper and C++ compilers/linkers have become much smarter (not to mention all compilers/linkers getting much smarter about code size). Sure, you can find pain points, but with a modicum of effort it's really hard to imagine a project really flapping outside the working set size purely due to the compiler/linker refusing to be drink from the water it has been lead to...

Tautologies are true, and identities necessarily hold. You are saying that a single dollar is a larger portion of a smaller net worth than that of a larger net worth, I gather. Of course this is true. The relevance remains unclear. It's the next step that is treacherous.

Interesting that "actual sleep mode" is mostly prevented because of cellular activity.

In any case the conclusion is mostly the same: the feature does not really appear to be effective at all.
That's not entirely true... E911 Phase II capable call centers (which is more or less all of them, per FCC mandate) will receive GPS coordinates from cell phone calls.

This works well for things like traffic accidents, where the caller may not know exactly where they are, but if you know the rough location, they're pretty easy to find (just look for the smashed up cars...).

It is a _lot_ less useful for a caller inside a house. We occasionally get dispatched to a geolocated address when a baby-sitter or some other visitor who doesn't know the house number calls from their cell phone. Unfortunately, even with the best accuracy available, it's still anybody's guess which house they are actually in (even in a suburban area, there can be several residences within the geolocation radius).

If they can get outside to flag us down, great. If not, it's a lot of knocking on doors until you find the right place...

> Our platform retrieves or refreshes around 400 user profiles per second (this is managed using 4 high-bandwidth servers co-located with instagram’s API servers on AWS).

Interesting, since Instagram's API only allows 5,000 requests per hour, (http://instagram.com/developer/limits/) and does not support bulk requests of user data. How does this application bypass this limit?
I think it was only supposed to be random when not associated at all (only during probing)
Yea after experiencing the buyout and watching it unfold over a year it got me more interested in how these deals work. One major question is - is the cost savings of hiring a worker in Texas with less experience at a 30% savings worth it if you're losing a few years of knowledge of internal workings and products? Very debatable and probably changes position by position, company by company. Also a buyout has a significant impact on general morale as everyone is now job hunting and wondering which week the layoff announcement is coming.

So something like "push to talk" is coming back to mobile phones. The more things change, the more they stay the same. Oh, maybe push-to-talk has never gone away.[1] (It's not a feature offered by my cell phone carrier.)

The article kindly submitted here with the interesting new news about phone-to-phone LTE communication reports, "In theory, LTE Direct could be used to create communication apps that route all data from device to device. Some chat apps can already use Wi-Fi and Bluetooth to link up nearby phones, but LTE Direct could offer extended range and better performance. However, carriers will control which devices on their networks can use LTE Direct because it uses the same radio spectrum as conventional cellular links. Wireless carriers might even gain a new stream of revenue by charging companies that want to offer services or apps using the technology, Qualcomm says." As usual, the actual implementation of this service will be all about carrier policies and business agreements.

Interesting, I know that it exists, so someone must be using it, but I actually don't recall ever seeing published web projects using ArcGIS. Why did you choose to use it?

Did you evaluate postgis + leaflet/mapbox?

edit: just looked into the subscription plan with ArcGIS and it seems somewhat expensive (and opaque - you are buying "service credits" which are consumed by how much you use their services - e.g. how many tiles are served, how much data is stored, etc. all use different rates of "service credits".

For those tl;dr, what Nick's writing about here is that you don't need to turn off cellular data or location services -- the requirement that the phone as to be asleep is instead too restrictive, because your phone is rarely asleep for long. (Those two settings let your phone sleep longer.)

> Unfortunately, the requirement of the phone being asleep makes this feature nearly useless, albeit within the description of what Apple advertised at WWDC. In order to get random MACs to be used I had to turn off notifications for multiple apps, turn off push email, and stay up late at night when there was a greater chance of my phone getting to sleep, uninterrupted, for more than a minute or two. Even under these circumstances, I would only encounter one or two rounds of probe beacons (which seem go to out every couple of minutes) with a random MAC before seeing my phone blast a bunch of probes with my real MAC. My best guess is this would happen when some process of push had woken the device up. With cellular data turned on, only about 50% of the probes I saw go out had a randomly assigned MAC.

But there's a worse problem, as mentioned in the last paragraph below from the iMore article:

> Rendering this feature even more useless, when the probe requests went out with a random MAC, the probes contained SSIDs of 5 networks that the phone had previously connected to. This means even when my MAC is random, the SSIDs it's broadcasting can act as a fingerprint for my phone. My MAC can be different every time probes go out, but if it broadcasts the same set of 5 network names every few minutes, it may still be possible for monitors to track my device.

>#1) Send a maintenance notice when no one will read it.

>#2) [...] Had we gotten notice on a monday, we could have switched servers or companies altogether. Hard to do that on a weekend with short notice.

These two appear to be the same.

>#3) Be sure to NOT use the word downtime. Disguise the issue as a likely small inconvenience.

>#4) Give Zero Expectations of Impact.

These two also appear to be the same. (These sentences themselves are actually contradictory, but the point of the description in these two are the same.)

>#5) Put details in riddle format. The official email said, “Maintenance window (all times CDT, UTC-5).” Whew! That cleared it up.

Why is specifying the time zone of the times given below a riddle? I can't think of any way to specify exact times in a simpler manner. I'm really not sure if 'When it's the middle of the day in some part of the USA' woul have served customers better. I assume there were times specified, as the quoted sentence wouldn't really serve any purpose otherwise.

>The Rackspace maintenance window was 6am - 6pm. Hmmm, thats odd.. thats exactly peak time. Sounds perfect.

You have no way to know how much traffic Rackspace serves in that timespan, Peak time for them might be way different than your peak time. They serve all kinds of countries all over the world, you know.

>#7) Spin lack of information as “protection.” Certain details? Like estimated impact? Progress estimates?

Most likely, they are trying to deceive anyone there, they should obviously be referring to lack of information about the issue's nature, not lack of information about maintenance work.

>#8) To pacify frustrated customers, just lie. I called into support 50 minutes into the outage and was told the migration was 85% complete. That pacified me enough to get off the phone. Then two more hours passed.

I don't think Rackspace was actively trying to deceive people. This sounds more like an issue with unexpected issues coming up, or the customer service rep being poorly informed.

>#9 Bonus Tip) Direct customers to remedies that dont work. My support gal was empathetic but at best, offered me the option to create a ticket so I would be heard by those who care. Lets forget how impersonal that is for a moment.

'Heard by those who care'? Again, I find it hard to believe that someone whose profession is to resolve customer issues via phone would care any less than people on the other side of the ticketing system. It is more probable that the representative was just unable to assist any further.

In my toy scheme interpreter I used two bits, and so could store integers, pointers to C functions, symbols, bools and characters in an "immediate" form. With the caveat that cells (which contained things that couldn't fit in immediate form) had to be aligned on a four byte boundary.

Just showing the different things you can do with tagged pointers I suppose. It's pretty common in Lisp/Scheme runtimes. I love bit twiddling hackery.

Hi minimaxir. We have a large number of tokens from our clients and people doing oauth to access our free demo. Since the data is public, we can use any of these tokens to access hashtags and account followers, etc...

Actually, Instagram API limit is pretty high when compared to other platform. Today we have something like 100k tokens available to us, which means we can make 12bn+ calls everyday. Almost like having a firehose. We don't use all of them but we're one of the top users. Though there are at least 10 bigger users than us on the API (according to them of course). Hope it helps!

There's an inherently subjective aspect to money anyway, though. The whole basis of capitalism is that people trade because it's worth it to both parties, and that value is created out of thin air due to the trading. It seems specious to object to progressive taxation on the grounds of "subjective value", while still defending capitalism itself.
No, we want it there too. We're moving to ArcGIS and just haven't finished adding it yet. It's very near the top of the to-do list!

How does something like the Tzar bomb compare in terms of sound pressure? Would the immense volume of ejected material from the volcanic explosion move more air than a nuclear explosion? I'd guess lots of mass (air molecules) is just vaporized in a nuclear explosion, leaving much less mass to create pressure deltas.
