> So what specific part of HFT operation makes them able to do that?

Lower costs by having computer programs rather than human traders. Two or three programmers can do the trading that would previously have taken a hundred traders, and there's a corresponding saving in salary/bonuses/etc.

> If either of these aren't core to what enables them to dump prices, we could get them down even more by getting rid of these toys.

How would you do that? Having algorithms is core to it. Having custom fiber is only core to beating the other HFTs (they can't compete on price so they compete on latency), but what are you going to do, pass a law against installing optical fibres?

Prices are already as low as they're legally allowed to be (sub-penny rule). Which is what causes a lot of the weird millisecond-chasing.
The company behind this is bankrupt and shutting down. I would avoid this software and there is absolutely no guarantee for service or support.
It appears to me that LinkedIn is splitting their API into separate categories (Profile API, Company API, etc)

Going forward everyone will have to register and be approved in only 1 of the categories, meaning that if you are in the Company API, you won't be able to utilize features of the Profile API.

I don't know exactly what that means as far as specific features, but my guess is that if you're a company you won't be able to access personal profiles and feeds. I could be totally wrong about this but that's what it looks like.
In China, everyone reads books on their phone and China Mobile is the biggest telephone service provider and e-bookseller. What is iPhone penetration like in China? The iBooks store won't permit Chinese language books. Better think of an Android app as well.
Cherry MX blues are godly for typing, be sure to check if your wife is fine with them though - they make a lot of noise.
> Remember when we all switched from Firefox to Chrome?

I remember the hype, but I never switched. Firefox was always good enough for me. And really, Firefox overtook Chrome in performance a while ago already. And naturally Mozilla's manifesto is way better to support than Eric Schmidt's "you don't need privacy if you have nothing to hide" idea.
Did you report it?

It is interesting how much pricing can really help drive revenue :-). It's really hard to know what works without experiments.
What drives me nuts is the fact that even after I explicitly close it, Chrome insists on opening up all the tabs I had open before. Reloading those tabs takes time, and I can only pray it's not some poorly coded webpage that performs an undesired action based on the URL. If I explicitly close an app, my expectation is that all the resources I had open close as well (to be fair, Atom does the same thing)

How to do good as an engineer
Poor browsers, the punching bag of all technologists. About the only software more despised/criticized/argued about is systemd.. that's saying something.
I remember one or two extensions I liked started injecting ads into pages with updates, which led me to uninstall them but would probably go unnoticed by a lot of users.
IIRC Chrome did not have this feature day 1, they added it after the fact. That's not to say they didn't plan for it but still.... Also "Chrome benefited greatly simply from observing the design decisions of Firefox, IE, " Yes and Firefox benefited from observing the browsers before it, so what?

> "In ten years (assuming Chrome is still around then), it will also have similarly antiquated design decisions that make sense to us now,"

You can't say that with any certainty whatsoever maybe Chrome will fair better than FF has or maybe we will see a re-write of Chrome's core to deal with future changes.

As I said elsewhere in this thread I will use the browser I deem best at the current point in time. Right now, for me, that browser is Chrome (I couldn't care less which browser has been around longer).

As for "it just means that it's not great to compare a brand-new browser with one that's been around (and used!)[0] for a long time" this is so wrong.... of course I can compare the two, they both do the same thing at the end of the day (provide a portal to the internet). When FF came out (and in it's heyday) no one said "You can't compare FF to IE, FF is a brand new browser" No, instead they/we all switched to FF because it was BETTER. Now, at least IMHO, Chrome is BETTER and so I've switched again. If that changes I will switch yet again.
One of the "alternative" services these folks recommend is academia.edu - does anyone else find it really weird that a for-profit-not-even-remotely-degree-granting company is squatting in the .edu namespace?
This is probably b/c most people at Google use computers with 32GB of ram.
Is there a better way to report the bug than just use the built-in crash reporter? I still get super sporadic crashes, I think it has to do with having too many tabs loaded.

We've been there for some time. People always have a knee jerk reaction to the word "fascism" and tend to reject it, even when it's a correct label.
"I downvoted you"

No hard feelings. I lived through a fair share of flamewars, and stuff like karma holds little meaning to my overall well being.

"while certainly there are women and minorities on IRC, I've seen few environments that could turn incredibly ugly and sexist and bigoted so quickly, or that could wear women in particular down so quickly and drive them away."

Here is the whole problem - claiming that IRC is bad for minorities is like claiming that all establishments serving food and drinks are.. and while this may be true for pubs, it certainly is not for restaurants.

It all depends where you hang out, and on technical channels, I have never seen anything that would suggest that minorities are not welcomed.. in fact nobody cares who or what you are, and you have no reason to share that information if you believe that this somehow may affect how people treat you.

Yeah the marijuana community always seems to be on the cutting edge of growing technology, much the same way the gaming community often leads use of cutting computing technology.

I've built a small tool to aggregate profiles together and I use it for my hiring. It builds a profile that is a bit more useful than LI. http://ars.io
I did that a long time ago

For example I don't buy sugar, at all.

All my sugar intake comes from stuff that has sugar in it, like the occasional sweet chocolate...

As for exercises... I try, I can even do some months, but after a time they start make me feel extremely bored and I cannot even pay attention to them while doing them, so I stop.

After a while I start again.

The exception was Kung Fu, but I have right now no accessible decent academy.
Eh, I mean, the URL is news.ycombinator.com which is pretty innocuous.

"Hacker News" is just in the title of the HTML document.
So turn off that setting then.
Can you people explain why you are downvoting me for my anecdote?
I'd hate for this to become the revisionist history of the migration from FF -> Chrome.

When I finally made the move FF had no extensions, no malware or any add-ons. I ran the same (mostly) version on Ubuntu, OSX and Windows 7. It had become unusably slow on all platforms. Looking around on the Internet in those days saw enough validation of the problem being widespread in terms of speed and memory resources that I tried Chrome and found it significantly snappier.

In fact, I still do, although I note the great strides FF has taken in that regard. My problem is I haven't seen the same degradation in Chrome that I saw in FF a few years back. If it's getting bloated, I've missed it (in terms of palpable heft with slowdowns, crashes).
Note to hopefully avoid unproductive tangents: all the views I use as examples here say nothing about how I feel about these issues, they're just examples of how _society_ feels and may feel about certain things (which is what is relevant).

> If you're against same-sex marriage you're probably on the wrong side of history.

The problem I have with this is that it condemns the vast majority of society, throughout the vast majority of history. Understanding someone's views while stripping the context of society's views at the time is foolish. In 2015, being religious (e.g.) isn't a good excuse for opposing gay marriage in 2008 (when a majority of society was in opposition to gay mariage, btw). Hypothetically, in 2025, maybe support for Israel's actions vis-a-vis Palestine will be widely considered the new apartheid. Similarly, what if in 10 years, we decide that a robust social welfare system in the US is a moral imperative (there are many who already feel that the way poverty is treated in this country is a huge moral failing)?

Does that mean all of my friends in 2015 who donate to and participate in organizations and rallies in support of Israel should be forever blacklisted from public positions? Should all the people you know who in 2015 are opposed to robust welfare/basic income and the accompanying tax increases be forbidden forever from rising to certain positions of authority in entirely-unrelated fields?
Similarly, I've been using it for 15 years. While I don't get jobs from recruiters either, I use it to keep connected to former colleagues even as they change jobs, email addresses, marriages and inter-state moves. This network gets me work.
I hate LinkedIn, and wish it was not a de facto requirement for getting a job in certain industries/areas.

To make it not so, _users_ need to stop using Linked In.

This OP is very developer-focused in it's audience, it will not be clear to the non-developer user (or even to many developers) what they are talking about at all, or why it matters. It is written assuming you already know what they're talking about and already agree with them about it.

There are plenty of things that might matter to users and help convince users that Linked In is an untrustworthy company -- like, their email spamming/address-book-stealing practices. I was hoping the OP would be more user-focused in it's intended audience and more intentional in making a case.
If you have Electrolysis there should be more than just firefox and plugin-container. Currently I run Nightly as my main browser and have to keep it disabled though due to some plugins I use lacking Electrolysis support (the fix is not on the plugin maker's side.)
Thank you, that was exactly what I wanted. I've got Firefox 35 now and if the UI stutters are gone I'll be back permanently.
Yes. Sandboxing makes sense when you think of browser as operating system. Isolate each process to increase security and crash-resistance. Makes sense, but it takes more memory.
Thanks for the tldr; but what does `pulling a Twitter` mean ?
President Obama is scheduled to speak at 1115.
> But, without the proper incentives simply privatizing or reducing regulations are going to do little but line someone’s pockets.

Well, that is true every system - including functions of government. It has nothing to do with privatization vs nationalization. The government mandates that certain financial instruments must be rated by a short list of companies that have been blessed to do so. So the government has limited competition among rating agencies, a laughable mistake in judgement. Then these companies only get paid by the folks trying to sell the instrument under review... another stupid move.

Many government programs, presumably setup with the best intentions, have serious negative consequences because the moron behind it didn't think more than one step ahead. This happens in private industry as well, the difference being that there the market corrects for mistakes by mercilessly crushing fools. In government the fools live on, and their plans are slow to change because it is now law.
At some point, if Fabrice and Bunny go into a startup together I will give them any amount of capital they need up front to get going :-)
As a short answer - not yet, but it looks like in 2-3 years there will be at least one.
Those "objective comparisons" then probably compared the rendering engines or some other micro benchmarks.

My main problem was the GUI, not the rendering (though the latter probably played its part in slowing the GUI down).

Opening/closing/moving tabs was sluggish.

Just opening Firefox with my ~20 tabs open would take many times as long as opening Chrome with the same number of tabs.

You didn't need a stopwatch to see the difference.
Happens all the time. "Ghostery is updated!" "Thanks for updating RES!" "More update tabs opening up!"
Not OP, but I would defend it with something similar to his statement above. Basically, I want to get the content out, and the extra effort (if required) would be enough for me to say basically "forget it". I'd rather get the content out and have a small subset of people not be able to access it, than not get it out at all. Certainly, there are other ways to make content available to specific user groups that requiring the original content creator to build it in from the beginning.
I don't think I ever granted them access, but somehow they got a list of random email contacts. So every once in a while I'll get an email that says, "Connect with Joe?" Looks like a normal inbound connection request, but it's actually a trap to get YOU to initiate a request. Awkward for contacts you might accept a request from, but not reach out to.
Linkedin provides me with a constant stream of useful contacts, leads, etc. Linkedin is by far the most useful social network to me.
Chrome 1+, IE 9+ and Safari 7+ spawn child processes with less permissions ("sandbox") for almost every tab.

Sadly Firefox 39 (nightly) still has no real multi process support. There are only two processes, the main process holds all tabs, the single child process "plugin-container" holds all plugins (Flash, Acrobat, etc.). It's a bit disappointing to see such little progress since 2010. Hopefully Mozilla's Rust based Servo engine comes to the rescue soon and replaces gecko and its old XUL (XML based UI framework) with Servo and an HTML5 based UI (like Firefox OS).

I use Firefox as development browser because of Firebug and and the new developer tools. Working with dozens of tabs open for days is only possible with IE11 and Chrome.
Nonsense. You teach someone arithmetic by showing them concrete instances where it applies, counting apples or sticks or so on. You demonstrate that the abstract thing exists because there's something the same about putting two apples and two more apples together or putting two stones and two more stones together, and by observing one you can learn something about the other.
I'm uncomfortable with allowing prosecutors the leeway to just kind of decide who should be in jail based on gut judgements but I'm clearly in the minority because that's not the way the law or politics are moving (like look at the guys getting nailed for mail fraud because of Massachusetts patronage scandals that technically were probably not illegal).
Plus, you really should be comparing the number of pumps, not gas stations. Additionally, the power throughput of a gas pump is way, way higher than a car charger. (Probably measured in the dozens of MWe per hour, compared to 50 KW/h of a DC fast charger) A single car ties up a gas pump for five minutes, an electric car ties up a charger for half an hour.
This makes no sense at all, I didn't use Chrome till it was stable....
Unless Firefox opens sites instantly (instead of 1-2 sec wait) then I don't see any speed benefit.

I'm gonna go out on a limb and say that the author probably has a lot of heavy addons that do stuff that is not needed. Biggest example probably is AdBlock Plus which bogs down any browser considerably and poking around with family's and friends' Chromes I see that a lot of them have several ad blocking extensions as well as couple privacy extensions is it any wonder Safari or Firefox with no addons is faster?
I was at the Fairway up on 132nd and riverside Dr last weekwmd, and they.had the competitor sauce you speak of. The big difference I noticed was they did not have any sodium benzoate preservative like the original siracha. If only they would give up in the preservative, I'd eat it again. Some real good all natural alternatives out there though.
"A simple `/ctcp $nick version` would be quite insightful to the tastes and possibly technical floor of the user."

insightful? it tells you if the person uses irc on a regular basis already (in which case they might have a native client) or whether they use something else usually (in which case they might use the simplest web-based client they can find on google).
Many, many, people have been burned by this same thing.

I think we need more advertisement of this terrible practice -- and or try to get google to aggressively block their access to do this sort of thing from your gmail, as what it is -- essentially a phishing/malware attack.
I don't think anybody familiar with the two services had any doubt that this would happen, eventually.

Squirt.io is another service that does the same thing as Spree, and I can't imagine that it won't soon be in Spritz's crosshairs as well -- especially since in its Acknowledgements section, the first to be credited is "Spritz Inc, the company whose patents are pending."

One thing I'm curious about is whether leaving the code publicly accessible, but in a "commented out" state, ostensibly rendering the program non-functional, is sufficient.

Like, suppose I wrote a small open-source text editor whose default text upon startup is the entirety of "Fifty Shades of Grey." And E.L. James' people contact me and say, "Hey, you can't do that. E.L. James holds the copyright to that text." If I merely comment out the text, rather than wipe it from the source code, have I really fulfilled my responsibility to not infringe on James' copyright?

I think that's fine, but they shouldn't just take everything GS says on faith.
Holy crap why?! Pre/post hooks to encrypt/decrypt seems like it'd be 100000x easier.
i never switched from firefox, with vim like extension, never had problems.

I haven't found any notion about good scalability as a feature. Could you provide a link to a good article about it so that I could mention them
I think most people on HN using FF are running nightly versions, I know I was. The nightly versions of FF have always had the edge on Chrome, but I think it's just recently that the stable version of FF has really gotten pretty much on par with Chrome, and I'd say definitely better on the Linux 64bit.
Chrome doesn't work well for me on Linux at all, whereas Firefox functions beautifully.

> Would future civilizations go through the trouble of understanding our video codecs? Machine language?

I would say yes; we go to great lengths to extract information from hard-to-read ancient sources, so future civilizations probably would too: http://www.bbc.com/news/world-europe-31087746
Frameworks and libraries contribute to "deskilling", because they mean that the developer has to write less of the application. But they don't totally de-skill the profession, because somebody has to write the framework or library, and somebody else has to learn how to use it.

The whole history of computer programming since at least the creation of FORTRAN can be regarded as this process going on. But it actually hasn't lead to the commoditisation of programming (except perhaps web programming and business apps). Instead, programmers have become much more productive. This means that many more jobs become economically viable, and so there are many more programmer jobs available.
Closing down APIs once they're big enough to not care more about developers and early adopters.

I hear quite a few people talking how they have 30-50 tabs open, how do people manage something like that? And why would anyone need so many simultaneous tabs open?
It seems like the vast majority of the issues with the current generation of products on the market has to do with speed & reliability; thus hardwired is the only way to guarantee those 2 work all the time. Also by going the hardwired route, the sensors and controls will be vendor neutral; thus ensuring that it will be future proof.

After doing a bunch of research the conclusion I came to was Opto-isolated relays [1] are the way to go for lighting control [2]. This allows for simple logic boards to control line voltage things without the risk of the line voltage killing your logic board. Best way to do this style of home automation would be in new construction, as retrofitting it would be hard to do if the house is more than 1 story tall as you need access above and below. Would be labor intensive as well. Will also allow for manual control because you'd put a current sensor on the wire so the hardware can tell when the circuit is on/off.

I would also want to put in some thermal cameras, as motion sensors are not as useful when your sitting on the couch, to tell when you enter/exit a room for auto lighting control. Put temperature sensors in every room and have motorized dampers & air flow sensor allowing for the control of the temperature in every room. Now your lighting and hvac can be manually or automatically controlled. Wire all the sensors and controls to a hardware/software brain that can be upgraded at any time. If that hardware/software brain is disconnected, all the light switches will still work and the normal hvac system will still work; just less efficiently.

Have the thermostat be controllable from the panel when the house is occupied (thermal camera) and auto controllable when vacant.

All of the above is possible right now; it just would cost a lot of money. Every relay/current sensor is $80 bucks; every damper control is $100; every thermal camera is $500; add it all together and you got one very expensive home automation system. But it will work right now without a lot of user frustration.

The initial comment asked for the benefits of HFT. All that comes up is that it improves the performance of markets. If you need economic growth it is a good thing to have efficient markets, incentives to invest and be rewarded with a share of the growth you enabled with your investment. But without the need for economic growth it just becomes transferring wealth from the workers to the usually already well-off investors increasing wealth inequality.

One flaw in your analogy: The FBI doesn't "haul you off to prison". There's a criminal trial that happens in between those two points.
This is probably me being my annoying self but one thing I absolutely cannot stand on Chrome are those disgusting grey circled arrows that show up whenever you swipe left or right on the trackpad to go forward or backward in history.

That's enough for me to stick with Firefox.
