Qualcomm Takes Down 100+ GitHub Repositories With DMCA Notice

ggraham412 There need to be costs (349 comments)

There needs to be a cost for issuing overbroad DMCA takedown notices.

If a court finds out later that a company had no standing or no good reason to make a DMCA claim that resulted in a takedown, there should be statutory damages. Let's start at $10000 per infraction.

Teaching College Is No Longer a Middle Class Job

ggraham412 Supply and Demand. (538 comments)

At a time when tuition prices are rising faster than ever, why are we skimping on the most fundamental aspect of college?

Because many more able people want to teach than there are available positions.

High Frequency Trading and Finance's Race To Irrelevance

ggraham412 Now that Lewis's 15 minutes are up... (382 comments)

...time to spam us all with another article on HFT.

it allowed the high frequency traders to peek at the ballots others were sending in to the newspaper before they arrived, in turn giving them the ability to cast their votes using information not yet available to the rest of the market.

Front running is not High Frequency Trading. The existence of front running is not an argument to limit "High Frequency Trading" any more than phishing is an argument to end high speed internet.

Until people can recognize the difference between front running (a biased ordering of particular market events) and high frequency trading (low latency response to available market data) then there really is no point in responding to this nonsense. Not as much fun as donning the tinfoil hat, I know...

A Measure of Your Team's Health: How You Treat Your "Idiot"

ggraham412 Mr. Kettle meets Mr. Pot (255 comments)

The manner in which the team members and project leader treat its weakest member is a symptom of the team culture, and a mark of its health. If you treat people well, they respond – and that always shows in the results you produce.

So let's pen an article referring to said weakest members as "idiots" and "dummies".

SEC Chair On HFT: 'The Markets Are Not Rigged'

ggraham412 Rigged Market != HFT (303 comments)

As usual, tales of rigged markets and front running are equated with HFT, and modded up +5 by people who need to step back and take a deep breath. Please ponder the following points and think again.

1 Front running is what we call it when a market participant gets a peek at orders before they go to market. You could send your orders in on a post-it note on the back of a snail, and if that participant sees and acts on them before they go to market, that's still front running.

2 Flash trading is what we call it when an order is shown to a market participant for a brief moment of time before they go to market. Sounds like front running, right? Except that (at least for DirectEdge customers) you can flag your order to not be subject to flash trading. Why would anyone voluntarily subject their order to flash trading? Who knows - maybe they get a break in commission - the point is they can turn it off.

3 Rigging the market may also include self trading in an attempt to boost apparent volume at a price, or quoting prices you don't intend to be filled on to goose the market. Both of these practices are already illegal and well policed by the exchanges and the SEC.

4 The "liquidity" that everyone pooh-poohs is part of what makes things cost what they do. Introduce more bid-ask spread in the commodities markets, and the costs will go up for pretty much everything: bread, milk, gasoline, etc. HFT helps liquidity because it reduces the time for cheaper prices to percolate around the market.

5 HFT is there because the markets are largely FIFO, and the markets are FIFO because FIFO is unbiased. Can you think of a more unbiased match algo? Lots of people put forward some sort of time bucketed system, but it doesn't solve the problem of who gets filled when there are more buys than sells in a bucket or vice versa. Nor does it solve the problem of cross exchange trading where time buckets are not likely to be synced, and people deal with it by increasing the bid/ask spread they're willing to quote. (See #4.)

Sometimes, it really is more complex than "She's bought and paid for by HFT". Plus, if you can't bring yourself to take off the tinfoil hat, you might consider that opponents of HFT (like big banks) are precisely the ones who benefit if HFT goes away. Now back to your regularly scheduled screedy goodness.

Lying Eyes: Cyborg Glasses Simulate Eye Expressions

Maybe this has greater applicability in robotics? It's probably cheaper to outfit a robot with a pair of these glasses that try to mimic the complex expressions of eye movements with tiny motors.

Mozilla CEO Firestorm Likely Violated California Law

ggraham412 Obama evolved his position, why couldn't Eich? (1116 comments)

The crux of the issue is that social attitudes are in flux on this matter. If you don't give people leeway to change, they will likely harden their positions.

And if you give some people leeway to change (eg- Obama, Hilary) and deny leeway to others (Brendan Eich) you are being blatantly partisan and unfair.

Adaptation From Flash Boys Offers Inside Look at High-Frequency Trading

ggraham412 Re:Front Running is not HFT (246 comments)

I agree on that definition of front running. However, my point was that front running is not synonymous with HFT. I think this is an important point; already the calls are going out to slow down HFT trading in response to the discovery of front running per the original post.

I'm saying it won't help. You could require that all orders get submitted to BATS on post-it notes stuck to the backs of snails, but if someone is looking at the snails before the match engine and biasing the market around the order flow they see coming in, that is still front running.

Adaptation From Flash Boys Offers Inside Look at High-Frequency Trading

ggraham412 Front Running is not HFT (246 comments)

Before you post an anti-HFT screed to Slashdot, ponder the question: Does the speed or frequency of the trading affect whether or not somebody is front running you? If the problem is that someone saw your order and acted on it before it went to execution, then the issue is with the absolute ordering of the events and not with the speed or frequency. There were front runners in the market long before electronic HFT trading came along.

A better term for what you're probably outraged about is flash trading.

Apple Reportedly In Talks With Comcast For Separate Apple Streaming Path

ggraham412 Can I just pay for Internet Service, please? (150 comments)

It costs X to provision and maintain internet service, you charge Y > X to a customer every month, and you clear Y-X in profit. Why is this so fucking difficult?

I've always viewed Apple afficionados as having an overly inflated sense of self-superiority to everyone else in tech matters, but I've always chalked it up to self-justification for the premium they pay up for Apple products and their patented rectangles. If their premium goes instead towards taking bandwidth away from me or bidding up the cost to me, then I may no longer be able to resist my ever present urge to take their iWhatever and "accidentally" drop it in a toilet.

Can Science Ever Be "Settled?"

ggraham412 Does science ever prove a political position? (497 comments)

Science is settled until new contrary evidence comes along to unsettle it.

There is an obvious contextual reference here to the contemporary scientific debate raging around global warming. If I may push back against the OP's question for a moment: The question "is the science ever settled" is not framed in a useful way. I think it is more useful to ask "does the science ever prove a political position"? I frame it this way because typically, when partisans point out that "the science is settled" on some subject, what they are really trying to do is put the weight of scientific authority behind their political positions.

Furthermore, I think this has demonstrable, detrimental effect on science. There has been a recent uptick in global warming disbelief. The typical response to this kind of thing falls into one of two categories: either Americans are unwashed idiots or the effort to disseminate scientific knowledge is somehow flagging in the internet age. But there is a third explanation which receives little attention; namely, the relentless push by partisans to make science speak for particular political ends brings science itself into disrepute. In this view, rising skepticism of scientific consensus comes from backlash induced by, essentially, partisan bullying on scientific issues. With respect to global warming, people see partisans making statements attempting to link currently held scientific views to political ideas that run the gamut from signing bad treaties like Kyoto, adopting economically ruinous policies, or enriching crony operators of new "carbon" exchanges. And then they conclude that maybe the science wasn't all that necessary or important to these partisans after all.

Physics Forum At Fermilab Bans Powerpoint

ggraham412 Bring back the transparencies! (181 comments)

I'm shocked that nobody has reminisced about the boxes of plastic transparencies and overhead projectors yet on this thread.

Physicists giving a talk used to struggle with finding an extension cord for the overhead projector instead of the right dongle for their laptop. The talk came in a box, and they used to fiddle with writing slides using transparency markers. You could write whatever equation you wanted!

Google Glass Banned from Restaurant

ggraham412 ggraham412 writes  |  about 10 months ago

ggraham412 (1492023) writes "

“If you do wear your Google Glasses inside, or film or photograph people without their permission, you will be asked to stop, or leave,” said the [restaurant owner]. And if we ask you to leave, for God’s sake, don’t start yelling about your “rights”. Just shut up and get out before you make things worse.”

As Google Glass becomes more widespread, more clashes like this and local policies to deal with them are inevitable. Would you be more or less likely to eat at an establishment that banned Google Glass, or doesn't it matter to you?"

Brazil Aims to Bypass US on Internat

ggraham412 ggraham412 writes  |  1 year,2 days

ggraham412 (1492023) writes "

Brazil is considering ways to make local use of the internet less dependent on US-based services, following leaks about Washington's cyberspy operations.The South American nation has suggested forcing internet firms to open data centres in Brazil, which would be used to store locally generated material. It is also pursuing a plan to build a new internet cable. The project would offer a way for data to bypass the US.

Interesting to ponder: how far are they and other countries likely to take this? Perhaps Balkanization of the internet was inevitable all along."
