The corporations have to pay higher salaries so people have the same take home pay
Not sure what fantasy world you live in. Corporations are under no such obligation to make take home pay constant. Most people I know do not get cost of living increases on a regular basis. So, inflation adjusted, and factoring in increased taxes (the norm in the US lately), most people I know are making less money each and every year.
Now, they'll ask for a ban of the device and people who will preorder will take the risk of waiting for ages before having their brand new phone...
Doubtful. The stock shows no sign of this worry. And I find it extremely unlikely that a US court is going to bow to a Korean company to ban a product in the US. There is little to gain for a judge in that position. Justice is not blind.
IMO HFT also "steals" a lot of top scientific and engineering talent from fields that _are_ socially useful The result is, these great minds aren't researching anything but how to pick other people's pockets.
Besides the fact that high frequency trading adds liquidity to markets that might otherwise be illiquid (and thus overall creates more efficient markets), quantitative trading has pushed the boundaries of the high performance computing market for the last few years, and continues to do so.
Network and compute companies are making better products, in part, because of a demand created for them within the financial industry.
Of course the real question is why you'd be trading in Hong Kong from the US when you can co-locate your servers in Hong Kong and run your trading algorithms there.
The strategy your parent is alluding to is a straight up latency arbitrage where you trade instrument X in market Z based on you getting information from market Y before anyone else.
Stephen Greenfield, the best professor I ever had, happened to be one who mainly taught undergraduate math to math, physics, and engineering students and graduate math. However, he had a passion for teaching unlike I'd ever seen and he worked on a course at Rutgers to teach math to non-sciency types.
The last paragraph on this page has a description of the course.
If you browse Stephen Greenfield's homepage, you'll find a wealth of teaching that might be able to be applied. He's since retired, but his page is still up, so make use of it!
In addition, many Costco labs (at least by me) are covered under this list of color profiles, often with specific information about the paper type and which printer was used to do the profile.
Since it is on multiple RAID 5 devices and I run a cron job that checks the MD5 sigs against a database I know that it is in good condition.
I applaud your desire to maintain integrity, but if something goes bad, you have to manually restore it. I, too, keep MD5 or SHA hashes of important stuff, but I rely on ZFS and 'scrubbing' for verifying integrity. The benefit is if a bit does flip, it will be corrected, and I will be told.
You know, someone could write an allegory about the desire for the geeks to have the consumer appliance "du jour" run an unadulterated Linux distribution. Call the appliance a toaster for all I care. It doesn't matter, because the story is always the same.
10 years ago we wanted some fancy hard drive based MP3 player to run our favorite distro. Now, it's phones. The cycle repeats.
The reason that the geeks will perpetually never be satisfied? We meet women*, we fall in love, we get married, we buy a house, etc.
At some point, you say, "I just want a damned insert name of appliance that works." And hence, Apple.
I may hate Groupon, but this person has no one to blame but herself. Do the math. If you sell that many coupons, even if only a fraction of them are redeemed, that's a lot of cupcakes.
Better idea - add a low fixed tax on any stock trade, regardless of value or size. Just a $0.01 per transaction would make HFT extremely costly- if you're executing millions of trades per second, that quickly brings you up to billions of dollars per trading day. HFT can't be that profitable. Yet it wouldn't really affect people making actual investments - ones where you actually investigate the company to make sure it knows how to earn a profit.
Yea, what a horrible idea. You'll realize how bad an idea that is when you want to go unload your "investment" and no one wants to buy it.
Liquidity comes at a price. Those who provide liquidity take on risk. It's a generally accepted practice to pay people for taking on risk (see, for example, interest rates).
However, the amazing advancement in network technology and all these crazy RDMA and 10G user-space network stacks is literally due to the HFT community
This is completely true. Financial applications are driving HPC components in a way that educational and government spending haven't in years and years of use.
Where do you get these price feeds from (or route the prices to) ? surely you could save 5e-7s just by using shorter cables or putting the mic and speakers closer to the traders.
Nearly all market data is transmitted from the exchanges via IP multicast. Typically you will have servers in each exchange to trade on that exchange, but you also will have links pulling in market data from every other relevant venue as well.
See, for example, Spread Networks who made a lot of money by digging a really straight trench from Chicago to New Jersey in order to get CME data to the NJ metro area as fast as possible.
there is absolutely nothing, whatsoever, 'valuable' behind a credit default swap. it is a bet. that is a fact, and its not rocket science, and its not a conspiracy theory, and its not "the ignorant and alarmist" decrying some nefarious boogey man.
You're completely wrong. If you buy a bond from company X, it certainly makes sense to have insurance that if company X goes out of business, you still get your money. And hence, the credit default swap was born. The fact that someone may use the instrument to speculate is a separate issue.
People speculate on everything. It's what you do when you stock up on cans of soup when it's on sale. You speculate that the price is going to go up next week.
Debian based installation of tools required 4 hours, OS-X / Fink / Google research required 40.
If this is the case, you're an idiot. I'm sorry; I don't know an easier way to put it.
There is no appreciable difference between Debian and OS X in setting up a desktop environment to develop in other than that in Debian, it might make take me some time to figure out what video card driver to use.
What the hell took you 4 hours in Debian? It should take you about 15 minutes on Debian, or Ubuntu, or OS X.
Isn't the fact that it's "good, free, and open" the exact reasons the publishers wouldn't use it?
Depends on the band. For instance, I haven't bought a CD version of a studio release from Gov't Mule in quite some time. They offer MP3 and FLAC for purchase right on their own website.
Phish even sells what they call "FLAC-HD" versions. These are 24 bit/96 KHz versions of their live shows.
Not to mention, these, and hundreds of other, bands allow people to tape and distribute copies of their live shows. Those recordings are FLAC as well, often higher than CD quality.
I see this all the time yet Apple is the only one to act like this. Why doesn't Google get into hot water over Android, or Intel over all the open source stuff it does?
Because Google doesn't sell a product for which giving away free stuff for can be claimed as a significant upgrade without a price tag?
I'm tired of people complaining about this. If Apple didn't do it, and someone latched on to it as a reason for them to suffer sanctions for improperly disclosing revenue, then everyone would be saying that Apple is a fraud because they clearly have unethical accounting procedures.
Speaking as a member of the developer program, big deal. Either pay the $99 for the year or pay the one time $4.99. Chances are, you'll get XCode 4 for "free" with Mac OS 10.7.
Speaking as a shareholder, this is just one more example (in a line of many, many others), why SOX hurts the US economy and stunts ingenuity and growth of US companies.
What that means is indeed absolute proof. Unless an error is found in the math, this means everything we've been told about the "benefits" that Wall Street offers society, for at least a generation, is hogwash.
You're an idiot. No, seriously, you are. The fact that you can take something you don't understand and make a sweeping statement about something else you don't understand is direct testimony to your [lack of] intelligence.
The proof is about lack of a closed form solution for an options pricing model. There are plenty of real world engineering problems for which analytical solutions do not exist and only numerical solutions work. Yet, we don't worry about planes falling out of the sky or your TV not working because you can't "solve for x." Same deal for this.
Yes, because Rolling Stone is the perfect place to look to understand the goings on of the world economy. Matt Taibbi is an idiot as is anyone who reads what he says and doesn't laugh.
I used that service a *lot* until last October they switched to Ensenda as the carrier in my area.
They did the same thing with me. Overall, Ensenda was fine for some packages and a disaster for others. Makes sense if you read up on them. Your packages are basically delivered by a "man with a van." Unmarked vehicles show up and drop packages off. So, it's basically hit or miss. Especially if you get a driver who does't know your building (living in an apartment) and decides that not finding the building translates to "delivery attempted." So, whenever Ensenda screwed up, I was very vocal, as I never have a problem with either FedEx or UPS. After about a month of almost exclusively Ensenda, I haven't had it in 3+ months.
Plus you can get 48 10Gb ports in 1U. No one else in the industry can touch that density
Not entirely true. Arista has little secret sauce. They're using merchant silicon. Stay tuned for the plethora of switches about to be released based on the Broadcom Trident ASIC (64 10 GigE switch on chip, manifesting itself as either 64 10 GigE or 48 10 GigE + 4 40 GigE). Some (like Force10's) are already announced.
The differentiator in 10 GigE ToR switching is quickly becoming software.

Real case scenario to back this up unfortunately.
Which is why it's so nice of you to provide one of those "real case scenarios," or perhaps a study.
And I can't afford $99 a year for free apps that I code once and forget about.
Then don't write them. Free [as in beer] software that is not open source is the worst of both worlds.
I'd rather pay for a decent app than get it for free.
A good developer's time is worth more than $99/hour, so the $99 fee per year is really inconsequential in the long run.

You should consider it.
