Rate of descent is calculated from barometric pressure in a CYPRES.

When a CYPRES is turned on, it calibrates itself and uses the current barometric pressure to determine the reference ground. When you enter an unpressurized aircraft and begi your ascent, the CYPRES will arm itself above a certain altitude (1000 ft normally). When you exit the aircraft, the CYPRES knows your altitude because of the difference in barometric pressure between the reference ground and the urrent pressure. It will also calculate your rate of descent from change in barometric pressure over time. It will activate if you're too low and too fast.

Notice how the environment is fairly static. You're jumping right above your reference. You're in an unpressurized vessel so the CYPRES can tell when to arm itself. You're starting a descent by exiting a level-flying aircraft. Any departure from normal operating limits and the CYPRES will not arm itself or activate at the proper speed and altitude.

You want a system like fighter pilots have and not something skydivers use. The environments are different, the operational requirements are different.

A framework calls your code, a library is called by your code.

In the long run, when you start a web application using packages like "net/http" and the gorilla toolkit, sooner or later it becomes framework-like, because you start to group your code together, you refactor it and make it easiliy extendable _for the app you are writing_. So, every app becomes a framework on it's own. And what I like about Go is the fact, that building such mini framworks is easy, and does not take much time - but the most important aspect is, that you don't need a huge framework that does all the things.

Twitter's valuation isn't based on users - the stock is down ~35% this year despite user growth being 22% and revenue more than doubling.

The stock is being trashed because they missed earnings.

The S&P report itself said Twitter is experiencing very strong growth and little competitive pressure. It was downgraded because Twitter are investing their cash rather than hoarding it. Bond holders want companies to hold cash. What is good for bond holders is usually different to what is good for stock holders.

The long case on Twitter is that the fundamentals are good, the company is growing like crazy and that the market is undervaluing based on earnings which mostly missed because of one-off employee option and other writedowns as well as reinvestment.
Even if those kind of graph are bringing hope, we have to remember that oil is both a source of energy (by burning it) and a compact and cheap way to store energy. A solar panel is only the former. So comparing the cost of energy production is only half the story.

The problem is Twitter has even more significant expenses. What worries the bond rating agencies is if this will ever change.
The article feels like a slam against them.

> Twitter reported a ... 7% fall in timeline views per user

> -a 23% growth in its user base in the third quarter.

... I can't tell if that's a net volume increase or decrease.

> Twitter shares gave up most of the 7% gain made on Wednesday

If this is relevant to you, you're a day trader, and this would be very old news by this point. This is misleading as they're talking about the day-to-day price right next to the percent change over the year.

> Its shares have lost 37% so far this year.

That's not true. http://www.google.com/finance?q=NYSE%3ATWTR&ei=afBlVNPuCsXmr...

They're down 3.87% (1.61 points) from IPO to now (less than 12 months). Even if I was confused and picked their performance as a "year to date" it would be 23% down. However, if I cherry pick my data and find the high point from the short-lived spike at a very specific date 10 months ago (not a year), their shares have fallen about 33%. I'm sure it was cherry picked for when "today" was also.

Basically. I think this is biased junk or a financially literate reporter.

Frustratingly, I can't find the report on S&P's site.

After some digging into actual financial news outlets we can discover this is actually an unsolicited rating which are famous for being poorly rated.

Author of XRDPConfigurator here.

I'm also the author of X11RDP-o-Matic, an open sourced utility to automatically download, build, and install Xrdp and the X11rdp X server back-end; http://scarygliders.net/x11rdp-o-matic-information/

XRDPConfigurator itself is available to try out - versions currently available for Ubuntu 14 (.04 & .10) 32 & 64bit, and Debian 7/Wheezy 32 & 64 bit. I'm in the process of producing packages for additional distributions - the difficulty being making sure the python libraries the application uses are available in the target distribution.

The program was written entirely in Python, compiled to C via Cython, and subsequently compiled to object code dynamically linked to the python libraries.

I am however considering treating the Python version as being "the application was prototyped in Python" and re-writing it in C++, as that would help to solve dependencies on PySide and other python libraries - that might not be viable on my part due to not having done C++ for a long time. We'll see how that goes.

The xrdpconfigurator.com site itself is still a WIP. I'm busy making more content.

The application took me roughly 8 months to develop from scratch - a lot of that was due to Xrdp having lots of new features added to it in that time, which I just had to implement - the big one being the xrdp login window was made a lot more customizable.

The biggest challenge is time, and prioritising what gets done first - I'm a massive team of one who's doing _everything_ from setting up the web site (itself using django and weaving together djangocms, zinnia-blog, and oscar for the licensing shop back-end), running and maintaining the web and email servers, developing the product, producing the distribution packages, creating the site content, attempting to tell people about it (marketing ;) ) and probably lots of other stuff I've forgotten to mention :)
How much experience do you have composing I/O in Haskell to prove that I/O doesn't square with that concept? Others here have experience using Haskell with I/O, but you just seem to have a hypothesis without experience or examples to support it.
Speaking from the trenches here.

Banking, especially non-consumer banking (i.e. IB, prop trading operations, etc) is divided intro three tiers: front, middle and back office.

Front office are the people directly dealing with "clients" (or better "counterparties") and get shitloads of money and an aura of being business savvy and knowing where it's at. Basically it's sales, trading and some higher-tier management. Contrary to what one might think based on the "Wall Street" films, these people don't need to be smart or sophisticated. I know quite a bit of traders, who only finished high school.

Mid office are the people who do the actual nitty-gritty work, that one would actually associate with a working banking institution: research, risk oversight (in Europe mostly known as risk control), legal, compliance, marketing, accounting, ALM, etc. They usually earn OK, but nowhere near what front office makes.

Back office are the people who are there for the infrastructure. Transaction banking, for example (i.e. making sure that your transactions are settled correctly, that money is wired to direct recipients, etc.) Tech is in most banks a back office thing (especially if we are not talking about algo trading). They earn shit.

I'm involved in quant finance, so I hoped, that I would see a culture shift after 2008-2013 from get-rich-quick-with-other-peoples-money schemes to a more serious business culture, but that is not the case. I honestly don't believe that Goldie can change its culture so quickly.

The Simple Question Nobody's Asking About Net Neutrality
I've found that a lot of DSLR owners end up just sticking with the stock lens. Lenses are really expensive and stock lenses are usually pretty adaptable. For this reason, I've begun to prefer high-end point-and-shoots like the Powershot G16; it has many more features and much better processing abilities than my old Digital Rebel, and since realistically I'm not going to lug around the DSLR and 5+ lenses for any situation that may arise, I've found P&S cameras to be much more convenient and very versatile.

I would only use my DSLR if I knew I would need to photograph some circumstance that my P&S couldn't handle. I know this makes me a black sheep within the photography community and there are lots of people who like to make fun of me for it, but the reality is that unless you're trying to get a specific shot, a versatile, general-purpose lens is all you take with you on your DSLR anyway, and you're better off using the lighter, smaller, cheaper P&S.
Beanstalk - private repo hosting for business - just released a brand new code review tool that we've been beta testing for a while now. It's rather nice and addresses many of the rough edges of pull requests. It's definitely for same-company teams as opposed to large open-source collaborative projects, though.

> We are slowly managing to put bigger and bigger sensor sizes in phones, too, without any compromises in design

It helps that the phones are getting bigger. The camera in my Nexus 5 is a ton better than in my old Blackberry Pearl, but the phone is also twice the horizontal size.

This may or may not directly apply to twitter, but I really don't understand how unprofitable companies with no direct revenue model get such large valuations based on: number of users, and "potential" to profit from advertising.

Snapchat? Tinder? Twitter? Quora? Tumblr? Etc.

It seems like these are the companies that are viewed as prestigious and noteworthy by the media and startup community. Everybody wants to be the company that gets a massive funding from VC and millions of users. But all of these companies still have yet to prove they can really do it.

The only returns for investors so far is based on the fact that the theoretical valuation keeps going up, and it's self perpetuating. At what point are investors going to expect real earnings to justify the valuation?

Nobody (or very few people) seems to want to solve a real problem, or offer a really useful product that people are actually willing to pay for.

Everybody just wants to get a million users, get a bunch of money from investors, and cross your fingers that maybe one day you can figure out how to actually make the thing profitable. And if it doesn't work out? Well it's somebody else's problem right?

It's sort of funny that, as long as the investor community all agree on $X valuation -- you NEVER need to make a single dollar in profit because the next guy in line will cover your "loss." Or finally some giant will buy you out to acquihire or get rid of competition.

Probably sounds like I'm just a hater and ranting, but just my 2 cents.
> Its shares have lost 37% so far this year.

I think they simply meant 2014, and then it is more or less accurate.

Jan 1st to now is not a pretty comparison. Whichever way you interpret the figures they definitely not look good.
Petrochemicals http://en.m.wikipedia.org/wiki/Petrochemical
There is no _the_ way to use it. But I can tell you about how I use it:

- I follow a couple of industry professionals and companies to stay up to date with their updates. As a MSFT developer I follow MSDN, the .NET team, but also important players like Scott Hanselman and Scott Guthrie. By doing this I always get the latest updates.

- I never follow more than 50 people and unfollow everyone who posts too much... If there are so many tweets that you don't have time to read them, you're not being effective. Be picky about who you follow. You don't have to follow your followers in return.

- I use Twitter a LOT to communicate with people I'd otherwise have no access to, because I don't have their email or they are too busy answering me through the company mailbox. Twitter makes everyone (except for celebs) reachable. If I need some guy at Google who write library X, I just send him a tweet.

- I use the search to find what people are saying about my product, but sometimes I also use it to engage with people who are talking about a subject I'm interested in.

I would have thought that would be not enough but a quick Internet Search suggests that 16oz/450ml is about the optimal intake per hour. Huh!
This is an insightful comment, and the takeaway discussion is: is Twitter a product for just "quite a lot of people", or can they bend it to a product for everyone?

I think what investors are looking for is a move towards a product that is for everyone. But given that Twitter's core business / USP is precisely that it is not like "everything everyone else is using", could the conclusion thus be that investors had too high an expectation of what Twitter has to offer the world?
I don't see any issue with this, apart from the Clickbait title. As it stands at the moment at first install they would be blank, so they may as well put ads in them until you have surfed around enough to show something useful there.
Google Code needs web and UX designers STAT, or it will die.
Yea, I know it's a really tired subject, but twitter really needs a major overhaul from a usability perspective. I think they should keep the 140 characters as a limit for what is shown in peoples feeds, but the character limit should be much higher. This is particularly important when you get into a conversation with many people, and the handles start taking up most of your 140 characters (as Marc Andreessen recently pointed out). It's also really hard to follow conversations, and they get separated somewhat arbitrarily. You might scoff and say that this would basically facebook-ize twitter, but honestly I don't think that's a bad thing. Facebook is moving into twitter's space, so twitter shouldn't be be so slow to act or it will get eaten, IMHO.

Also, I use twitter to keep up to date on some of the industries I'm interested in, and while it's a great tool it's still frustrating sometimes, since there is a flood of info throughout the day. TweetDeck makes it better since I can group things by interest and triage depending on how much time I have. I guess you can do that with the web interface but I have never found it as natural as with Tweetdeck.
> but there's no mission and purpose behind, just making someone make big bucks. Quite the opposite in Sillicon Valley, I suppose, where one can build something that actually affects the world.

This is not universally true. One can find examples of SV companies that are not doing important things that affect the world (e.g., "Yo!") and one can find people on Wall Street who are making money and using it to affect the world (e.g., James Simons and the Simons Foundation).
Awesome what you're doing here with the video and the transcript. But can we make the transcript not include the pauses? It really throws me off the flow of the takeways when you put all the 'Ums' and 'Ahh's there in the transcript. It doesn't add at all to the message when reading it...

"Um, so, uh - so that was Twitch. And I'm going - I want to give you guys a little bit of a, uh - uh, a little bit of an insight into, uh, with Twitch what that, what that meant going to go talk to users."

I know keeping it real is great and all but for the people who are reading and not watching, it would be awesome if some editing could be used to make the read more succinct.

"So that was Twitch. And I want to give you guys a little bit of an insight into what that meant (when) going to go talk to users."

Minor irk of course, really appreciate what you've done otherwise, thanks.
Insofar as the largest, uncompressed version of a photo is its "source", I can see where s/he's coming from when using that term.
Sign up and follow people with similar interests. I follow very few people (approx 80) and remove anyone who starts tweeting things that's no longer relevant to me.

Within that timeline I get a decent amount of tech info from respected people in the industry and other small snippets from friends.

If you do as most people seem to and follow 500+ people you're never going to be able to keep up with the noise and to me it loses its value.
That's more a crop that gives you more "reach" than a true telephoto though. Of course most people just want more reach and don't really care for perspective when they say "zoom", so sensor array could definitely work for that. Also since a phone is just the right size to record stereo for vr as well, which is also bound to be the next big thing. Two sensors isn't far fetched given several applications for them, and low cost
I really don't know how anyone didn't see this coming. The Twitter IPO was the nail in the coffin for the company. It was wishful thinking that they would ever become profitable with their current model.

This seems to stretch the definition of "minarchist".
The math goes something like 'expected customer lifetime value * number of customers'. Where the lifetime value is based on either some base assumptions about conversion to a premium product or some base assumptions about what they feel they can make of their users in terms of ad impressions or some other relatively low yield income stream. If this yields a huge number then everybody is happy.

This is further inflated by exits such as whatsapp and instagram, after all if they are worth that much then surely this other non-related product will be worth at least as much or more.

In the end, valuations have a pretty high random component and the perceived market can push that up or down tremendously.

Who even knows what drove this company to issue a warning like this, maybe one of their bigger customers is planning a take-over bid. It wouldn't be the first time something like that happened either.
That was a typo, I meant 1%/day.

In my country, there are safe investments with guaranteed returns of over 12%/year (prefixed federal bonds). For instance, if you buy a LTN 010118 right now, it will return 13%/year (before taxes) when it expires on 2018-01-01 (the current buying price is R$ 684,17, it gives back exactly R$ 1000,00 when it expires).

Of course, that's if you don't look at the inflation. With inflation currently at 6.5%/year and rising, the true return is more like 6.5%/year before taxes, and more like 4.5%/year after the 15% tax on investment gains above 2 years. So yeah, if you do consider inflation, 1%/month is too high.
> I think that on the level of Netflix, they should indeed pay for special agreements.

I think this is a bad idea.

Firstly: This sets a hard upper limit on how much a startup can scale until the ISPs start to get to play favorites. Success thus becomes less about market fit and innovation and more about politics and back-room deals.

Secondly: Why should fairness and a level playing field be guaranteed only at small scale? Why should gatekeepers and oligopolies be given more power at scale?
Well, take the wired telephone (please!) Of course, "everyone can use it" but I bet since its invention, a few power users have made 100x as many calls per week as the average person has. They're the real benefactors. The only difference is that on Twitter you get to see who is doing this.

> secret courts and rulings erode the values of a free and open society.

secret courts allow the appearance of a free and open society whilst actually enacting draconian practices without fear of reprisal.
I don't think it is either good or bad, I think they should go their merry way but once you IPO you're putting yourself in an aquarium and this sort of thing is to be expected (assuming that the motives of this agency are pure, which is definitely not a given).

As I commented elsewhere in this thread I think it is ridiculous that a company can be taken to task about investing 12 months after an IPO but we're living in a pretty weird world where you're supposed to see your stock go 'up' every quarter or you're doing wrong in the eyes of the market. It's all perception and very little substance.

Comparing twitter with Visa is a bit of a stretch I think.
Ah, my apologies, didn't occur to me.
