Even with your hard constant of <200ms you haven't really specified enough to really talk about HFT with out being more specific. Is your constant the amount of time an algorithm holds inventory? If so tons of low latency systems can and do hold inventory for much longer than that.

Is it the amount of time it takes a computer to make a trading decision? Nearly any modern computerized system in under that time constant, and many non-low latency trades happen in that time frame.

Any electronic trading system (which I think most people agree are good things) will allow for algorithmic trading (how could they not?). The question is should we try to prevent low latency trading? If so, why? And how can we? Will any system we put in place cause more problems than it is worth?

Finally, if you don't think currency markets are fair, why use them as an example where you are getting better prices than you would be otherwise? Currency markets do not provide better pricing to all of their participants than electronic markets with HFT do.
I like that hammock shelter. To make a little "base" or home or whatever, you could put your stuff inside and have the ropes over higher branches, then lift it and tie down the ropes to keep out animals. If the emergency is of the apocalyptic or state-ending variety, a bunch of looted cable locks could chain together and even make it locking, making people climb to steal your stuff.

Then again, if this is in a go-bag, I suppose it all fits in the bag, doesn't it?

> I believe what Mr. Messersmith may have been referring to was a temporary restriction on Chinese nationals that you put in place earlier this year after serious security protocol flaws were brought to your attention by some in Congress, including me, specifically regarding violations at Ames and Langley Research Center. You indicated at the time that security policies for foreign nationals for particular countries of concern would be reevaluated and new accreditations would not be approved until the security process was vetted. However, any restriction against Chinese nationals on NASA centers is entirely an agency policy and not covered under the statutory restriction. Furthermore, it was my understanding that NASA’s temporary restrictions had been lifted after a review of security protocols for foreign nationals at all NASA centers.

As you know, NASA’s inspector general recently produced a report documenting the serious failures in the security process that led to violations involving a Chinese national at NASA’s Langley Research Center. I hope a copy of this report will soon be made public. For these reasons, I supported NASA’s policies that were put in place earlier this year to ensure that these security flaws had been dealt with. I continue to support every effort you deem appropriate to ensure that NASA centers are fully compliant with laws and regulations governing security.
> If you don't pay rent (eg you live with parents), its probably a net win. If you don't consume much housing (eg, 4 person house share), it might still be a net win.

The typical person in the job market has a spouse or children. Having to have multiple roommates on top of that is generally considered a nonstarter.

When you say, "If you don't consume much housing...," you're saying, "If you're single and unattached..." And it's only a net win as long as you stay that way, which isn't usually the case.

To connect the dots the rest of the way, when housing prices shoot through the roof, people with families and special needs get pushed out. What is left are people with fixed housing costs and single people who don't see having many roommates as being a quality of life issue.
The implication (point?) of the research is that older companies (regardless of size) create fewer jobs relative to younger companies.

I would disagree with the statement that reducing taxes on profits has absolutely no impact on overall job growth. Furthermore, a reasonable conclusion would be that reducing taxes on young (and almost by definition, small) companies independent of profitability would have a greater beneficial impact on job growth than reducing taxes on highly profitable and older firms (large or small).

Based on the research, maybe the best course of action for job growth would be to reduce all taxes (profitability and payroll) for young companies regardless of size and profitability rather than an indiscriminate scheme that reduces payroll taxes based on time constraints (such as 5 years of expanding employees) for all firms large and small.

The price for all this luxurious state of the art tech starts at around $300, which makes it affordable, but not really Raspberry Pi cheap by any stretch.

It's true that even having something like this software imbues a certain awareness of, "Gee, if there has to be special software to keep transmitted files secret...does that mean all the other times I've been transmitting files via email is unsafe?"

But even when the spirit is willing, the flesh is weak...It's been well known for at least a century that you should wash your hands before doing critical surgery...and yet today it's been somewhat of a revolution to mandate checklists that enforce this at modern hospitals. It's not because surgeons are stupid, it's because the workflow can be so dynamic that critical, easy steps are often missed when unexpected scenarios occur...especially when humans are involved (i.e. all major surgeons today)

I agree with malnutrition. In fact, many modern societies are malnourished due to lack of vitamins/minerals in the local staple. It's one of the reasons flour and cereals are usually "fortified". And in Asia, significant R&D efforts are not unusual to get rice to be more nutritious based on deficiencies in the local population. [1]

The problem I have is that grains are pointed to be alternative diet folks as some kind great evil by itself based on dubious claims around unsubstantiated reasoning. Like I said, some external factor is more likely the issue.

Actually, QML has included Desktop Widgets for QML since Qt 5.1 under the name Qt Quick Controls[1], which means that desktop-type applications are now supported for QML as well.

Having used those a bit, I have to conclude that they are FREAKING AWESOME. Sorry for yelling. If you are used to developing Qt applications using C++ and the Widgets only, please do check that out. It is amazing!

Assuming "we" is the young, tech-focused, urban demographic of hn: At least from my anecdotal experience, that demographic did apply an awful lot of effort in 2008 to get the President they wanted, a supermajority in the Senate they wanted, and a House majority they wanted. Did anyone think that a Washington that looked like that would have any incentive at all to modernize (sorry, "privatize"!) Social Security?
Thank you very much! That's great.

That is still different than voting for a party. In proportional representation you would cast your ballot for e.g. The Democratic Party. If they got 54% of the vote, they would get to then appoint 54% of the representation for that district. In this way, a very heavily Tea Party district would still have representation for the democratic minority, just less.

At $300 this is a tough price point, for $50 more I could get a fully functional laptop, sort of this system with a hard disk, monitor, keyboard and CD-ROM.

On the other hand, for $300 I could get 8 Raspberry Pi B's.

So while it's cool and all, not sure how it well sell at that price.
This shows a complete lack of understanding of what's has already happened in the Qt project (notice the past tense).

Qt widgets will not see any improvements. They haven't see any improvement for the last 2 years. Here, answer these questions for me and decide for yourself:
1. What new APIs were added in Qt widgets in last 2 years?
2. What new widgets were added in the last 2 years?
3. Is the Qt team working on improving various look and feel aspects of widgets on the Mac and Windows 8?

Just do a git log and see for yourself - https://qt.gitorious.org/qt/qtbase/source/HEAD:src/widgets.

Umm... What?

The 10-Q you just posted says AMZN pulled in $4 Billion in cash equivalents for the quarter which is almost double what they did the last equivalent quarter. It also says they have $8 billion in the last 6 month period whereas the year before they had $5 billion in the same 6 month period.

My point wasn't that they are making a profit, my point is that they are pumping enormous amounts of money into their own infrastructure. Looks at the capital investments section of the report.

Completely misleading. Have you ported a Qt Widgets project to QML? Show me the code if you have done so and I would agree that I am wrong. They are completely different code bases.

I don't have a problem that this solves. I don't consider tweets to be important data -- the value of a tweet goes to near 0 after 24-hours.

Problems I do have

1. Noise to signal ratio in reading tweets

2. Having ideas for what to post

3. Getting my attention drawn to important tweets

4. Managing interactions

5. Increasing relevant follower count in organic ways

I have solved some of these with custom clients, lists, ifttt scripts, and buffer
There is a difference between saying "Oh, that animal acted like a human, it must be just like a human" and "Oh, that animal behaved in a way that I recognize, it probably has some intelligence and capacity for emotion."

There comes a point when something is acting as if it is intelligent, or as if it has emotions, that it's reasonable to assume they are intelligent or they do have emotions. Not necessarily the same as ours, but on a spectrum.
QML is awesome, no doubt about it (and I am big fanboi myself). But that doesn't take away the fact that Qt Widget -> QML is basically a complete rewrite of your app.

There are themes for text editors which have both a day and night version (and some users will without a doubt have setup cron to switch automatically).

There are also blue-blocking filters recommended to wear at night for improving your sleep rhythm.

Of course none of this means that the f.lux author can’t obtain a patent on something related to his software. The question is if it will hold up if later disputed.
Can anyone elaborate on "prepares the ground for future developments using Wayland and Qt 5."?

Does it have any impact on this release? On the face of it, it looks like justification for not being able to list more user visible features. Does anybody know any different?
Righto, I was off-by-one on that, thanks :). We're currently transitioning to Qt 5.2 which involved upstreaming lots of things we need in there, so it's become a mental habit to think of anything shiny we're using as being new in 5.2.

So far we consider Controls to be very promising, but there's plenty of gaps (no form layouts, incomplete QStyle support, some pathological performance problems, lacking automatic keyboard accelerator management, plain missing standard widgets, etc.) that don't quite make it stand up in comparison if you're serious about desktop use (which we are), so I think it best not to overpromise.

We're making quite an investment into the technology anyhow, though; it'll get there with time (and effort).
A very thorough study by gwern and an enjoyable read.

I wish Firefox would do the same. Sailfish browser already does (which is basically Gecko with Qt UI based on IPC embedding API). There was initial work to make Firefox with Qt, but Mozilla never officially started supporting it.
I see branching as a logical infrastructure, somehow related to function, it isolates logic. Easy and frequent branching may help tailor this.

Expectancy and mood can really alter psychedelic experiences. Can't be sure for microdosing, though.

I am reminded of the ITU meeting a few months ago, where they wanted to make content filtering by nations easier to do, and the adoption of a "sender pays" billing scheme. As well as remove ICANN from under the US aegis.

As bad as the NSA vacuum is, it's a problem that can be solved under the current system.

I think there are a number of self-serving incentives for countries to pursue a "national firewall" model. Many of the same governments which (justifiably though maybe also cynically) decry the scope of US surveillance would probably welcome a closed network which makes it easier to perform their own domestic surveillance while appearing to liberate their people from the bogeyman of American tyranny. Content filtering (censorship) and national version of "American" sites like Facebook and Google (of course, all of which would filter money and data back to the motherland) are win-wins for the state as well.
I flew to New Zealand on Air NZ back in 2005. Unfortunately there's a stop off in LA to refuel and change crew. Everyone is taken off the plane and corralled into a holding area with not enough seats and horribly stained walls. There is no humour from the immigration officials who escort you through a myriad of corridors to this zone.

Then you're marched out in batches and electronically finger printed/eyeball scanned by more humourless uniformed officials before being deposited back in the holding area to await your onward journey. It was a demeaning experience and I wasn't even visiting the US. Technically I haven't entered the US, how do they get away with that?

This contrasted heavily to my previous arrival on US soil (Boston in 2002) which was pretty straight forward - visa waiver (I'm a UK citizen) thing during final approach on plane and traditional show your passport procedure at immigration and off you go.

Upon arrival in Auckland the only grilling we got was from a bunch of cheerful bio-security folks, with a cute sniffer dog, who wanted to make sure we didn't have any fresh food in our bags and that our footwear wasn't caked in dirt/earth (which could potentially harbour unwanted seeds or spores).

After my 2005 experience I decided that won't be visiting the US again, I'll stick to travelling in the EU.

It really is a case of just getting the word out. I know on HN there is sometimes the need to conceal identity but here is the perfect place to put a link to your product (its free advertising).

What you need to do is spend no more time developing the application (unless for support for the next few weeks). Use the time saved to identify how your competitors market there tool, the techniques used etc.

Then you need to identify website where similar tools are discussed and go there with the aim of helping people. Every so often mentioning a particular product that you know very well.

It will mean that when people come to buy products if they see your softwares name it will be in there thoughts.

Likewise try to connect with people and businesses on twitter and publicly reply to them and there needs explaining how your software can help them. Its amazing the number of companies who do in-depth analysis of competitors conversations with clients and potential customers.

Ah, never mind then. This is notable because neither Windows 98 SE or Windows 8.1 really are updates or service packs (it's not like the usual "KBxyz restores the start button in Windows 8" and it won't appear in Windows Update), that's why they have distinct names and packaging to set them apart from the other Windows versions. The MS press release / blog post (and related press coverage), however, made it look like the free upgrade was a first. I stand corrected, but I don't loathe Windows any less because of it.
Shuttleworth: Apple will converge Mac and iPhone
I use Erlang in some tasks. Its very cool system but not have some features such in PHP. No OOP and namespaces. PHP stay at important point now and must determinate vector for main moving. I think its may branch to FP and inspired on Erlang. Repeat again its may be branch. But without major types like lists and tuples and pattern matching its not quite...but I dont know. These things make major flower.

It may have more to do with anthropomorphizing than anything - it's much easier for an urban dweller to project human qualities onto animals like dogs, which they interact with frequently, than the slabs of pig meat they see in stores. A distaste for eating animals perceived to have more human-like qualities follows naturally from avoiding eating humans.
Theodore Roosevelt was made VP because a certain NY senator couldn't stand his political stance and wanted to make him irrelevant. Party boss Mark Hanna wasn't against his selection as VP but TR's overwhelming popularity due to his military actions in Cuba prevented him from inhibiting Roosevelt's momentum at the Republican convention.

"Don't any of you realize that there's only one life between that madman and the Presidency?"

Prophetic. Less than a year after the election, McKinley was killed by an anarchist and Roosevelt ascended to the presidency.

Hanna considered challenging him in the 1904 election (he really hated Roosevelt) but failing health prevented him from doing so—he died of typhoid fever before the campaign was under way, much to the disappointment of business interests (especially J.P. Morgan) who were fearful of Roosevelt's anti-trust tendencies. Morgan supported Hanna partially as retribution for Roosevelt's targeting of his rail combination.
No. The best kind of documentation is the kind that explains the non-obvious decisions taken in the code. Or the kind that outlines the interactions between function x and states 1-3. Or the kind left behind by some poor bastard archaeologist who comes in after the fact to fix the appallingly opaque ball of hair I pooped out under terrible deadline pressure.

Documentation has multiple purposes, and multiple audiences, and a good static type checker can't do anything for most all of them.
