As Crypto Mining Grows, Data Centers Begin Accepting Bitcoin

sfcat Re:Why would they accepts fantasy money? (94 comments)

The blockchain is nothing more than a transaction record. It doesn't "enable" anything.

Bitcoin (and all blockchain tech) solves the Byzantine Generals Problem which is a classic problem of computer science. It means you can create distributed exchanges of virtual or real property in the face of people trying to lie, cheat, or steal. Its actually a pretty big achievement. There are distributed market places, distributed exchanges and other interesting developments in the works all based on the fact that we can now build software on top of blockchains. But please continue to tell us how Bitcoin doesn't enable anything and whatever DB table you (or your bank) use to store transactions is more secure than that.

Sifting Mt. Gox's Logs Reveals Suspicious Trading Patterns

sfcat Re:Easy to solve (143 comments)

It wasn't foresight; same as for the EPA, labor laws, OSHA, ...

Wow. For you Tea Baggists - oh, I'm sorry, "Libertarians" - it always comes back to the EPA and OSHA...

He isn't saying there shouldn't be an EPA or OSHA, he's saying that people had problems then came up with the regulatory solution (ie creating the EPA). WTF are you responding to? I don't even think the GP is a tea partier.

PS I'm a Democrat, not trusting the FED (which is a rational position if you know its history) isn't the same as being a Tea Party member. Its just one issue out of many and one that quiet a few Occupiers would agree with (well the ones that know what the FED is anyway). Now go troll elsewhere.

Ph.Ds From MIT, Berkeley, and a Few Others Dominate Top School's CS Faculties

sfcat Re:dream on (155 comments)

Jealous much?

I had *no* fiscal support from my family for MIT: I was an emancipated minor at 16. Most of my peers worked their *asses* off to make ends meet. MIT is *filled* with people whose parents didn't or couldn't fund their full costs: they have a "needs blind" admission program that is very helpful to kids, and families, who struggle with the costs.

So you can take your jealousy and put it somewhere else.

CMU is much the same way. No legacy admissions and grants and scholarships are entirely need based and not an honor (like say the Rhodes Scholarship is). Keep in mind that this for the CS departments, other schools in the universities are a bit different.

Ph.Ds From MIT, Berkeley, and a Few Others Dominate Top School's CS Faculties

sfcat Re:dream on (155 comments)

It's just sad that we rely on pieces of paper to 'prove' our worth, even when most of the people with pieces of paper don't know what they're doing (Most of the people without don't either.). It's also sad that you need to waste your time in rote memorization facilities in order to get scholarships. It's just a huge waste of time and effort.

You know what you are? Bitter.

I would be bitter too if I got rejected just because I didn't have a certain piece of paper. That's illogical garbage.

But being "bitter" doesn't debunk his little rant. But yeah, I don't see why he would decline to hire someone just because they're rich; it seems like the same sort of petty nonsense that leads to employers not hiring people because they're lacking pieces of paper.

Clearly written by someone who never was at one of these top CS schools. I assure you that rote memorization won't get you a degree at any of them. Most of my tests at CMU were open book and open note and I can count on 1 hand how many times I used my textbook or notes during a test. Why? Because the tests weren't rote memorization tests but instead tested for your ability to synthesize what you learned and apply it to a domain you might not have ever considered. One question on my OS final was to write a device driver for an optical disk, with a pencil and paper (no compiler or debugger) in valid C. Rote memorization won't help you there. Quit being bitter and ignorant about educational experiences you haven't had. Perhaps there is a reason all the CS profs come from MIT, Berkeley and CMU...

PS Berkeley graduates about 4X the CS major as MIT and CMU combined. Not sure the author considered this in their analysis...good engineers are supposed to see this type of omission. Guess CIOs aren't...

Ph.Ds From MIT, Berkeley, and a Few Others Dominate Top School's CS Faculties

sfcat Re:dream on (155 comments)

When I went to job interviews (though it has been years), I made it a point to dress up in the 'worst' clothes I had. I'd go into job interviews with casual clothes that would have stains and rips in them. The idea is that I don't want to work with shallow people. I'm simply choosing my own company, and I don't want to hang around people that are irrational and shallow if I can help it, you see.

Again, this is a free world (for a little while longer anyways). That is your choice. I know people who did that same thing except they did it in order to flunk the interview so they could meet their job search requirements and keep drawing their unemployment checks while working under the table on the side.

This right there is why you didn't get a job with a software firm and ended up in IT instead. It might be a symptom of you not getting into one of these top CS schools in that when you are at such an university, you are surrounded by people who are as smart or smarter than you (perhaps for the first time in your life) and you realize really quickly that first impressions and looks are very likely to fool you when dealing with such people. You learn to look a bit deeper and you learn that a term like "smart" can take on many forms. Some people are better communicators, some are better engineers, some are better at abstract logic and some are more pragmatic folks that always make sound decisions. And how they dress rarely will tell you which someone is. So you learn to filter those factors and look deeper. Something you clearly never learned to do. And putting someone like you in a quality engineering team can be like throwing a wrench into a clock's gears. That's why you ended up where you did and no other reason. I've worked with people in the software field without CS degrees and with degrees from "lesser" schools. Your authoritarian attitude toward others is why you are barred from software firms, thank his noodley goodness.

California Legislation Affirms Privacy Rights Against NSA Spying Methods

sfcat Re:Now we'll see who's really the master. (96 comments)

Nice federal income tax revenue from California you have there, United States. Would be a shame if something were to happen to it.

This is a game that can be played both ways.

Its actually worse than that. If you remove CA from the US economy, what do you think the jobs/GDP/other national growth metrics for the rest of the US look like over the last 30 years? Can you say perpetual depression? Removing CA from the US would be disastrous, for the other 49 states. Don't kid yourself about the size of the CA economy, its large and growing, unlike the most of the rest of the US. Oh, and we actually pay off our debts. You really think politicians from other states would want to have to explain those numbers to the voters?

FBI Need Potheads To Fight Cybercrime

Considering I've never heard directly of anyone in this industry using it, I think the stereotype is correct. Personally I didn't see it in college (BS in Comp Sci in 1989) nor have I seen it in the twenty-five years since. Pot use just doesn't happen in this industry.

What qualifications should the 'driver' of a fully autonomous car need?

sfcat Re:Work the way down to no license (301 comments)

Early elevators weren't exactly safe. That didn't stop people from using them.

Yes it did. The thing that made elevators a success was a safety demonstration at the 1854 worlds fair. The guy who invented the safety break for the elevator Elisha Otis became the biggest maker of elevators (which is why you see the name Otis in many elevators even today). The maker who won was not the guy who first made a elevator, it was the first guy who could prove an elevator was safe.

Don't Be a Server Hugger! (Video)

sfcat The cloud is slow and expensive (409 comments)

I work for a startup that makes high-throughput SQL systems which handles millions of events/tuples per second. We tell our clients that they can run our software in the cloud but it only runs about 1/4 as efficiently as hosting your own servers. We are able to pipeline buffers effectively on local hardware, but the virtual abstraction layer destroys our performance. I doubt we are alone in this. So when you pay for a "server" in the cloud, you are really only getting 1/4 the I/O capacity as a local server and since we are talking about servers, their I/O capacity is really what you are buying. In my experience, virtualization is really about lazy sys admins who don't know/want to learn things like PXE and it does mean less time in loud and cold server rooms.

You know every time someone pushes something as hard as the cloud gets pushed, there is something worth knowing that they aren't telling you. In this case, its that the cloud will probably cost you more as you need 4x the number of "cloud servers" to handle the I/O load of your production servers. But hey, at least 'the cloud' sounds really cool.

Comcast Predicts Usage Cap Within 5 Years

sfcat Re:Caps Are Definitely Coming (475 comments)

There is the issue of certain services being 'natural monopolies'. How many power companies do you want running power lines to your home in order to offer you power service? Network companies running fiber, cable, or coax to offer you the Internet? Water? Sewer?

See, when something requires the customer to receive not just the service but also build infrastructure through other people's property to deliver it to them, most people realize that allowing many companies to build that infrastructure is a disruptive pain. Since we don't have the core infrastructure built so that such cables can be laid without disrupting someone else's property, the trade-off has been a limited number of contenders in an area. You can argue whether that's right or not, or if there are better ways, but that is what the compromise was in order to allow for the service and yet not be a disruption.

Personally, I see local infrastructure like power lines, fiber, coax, cable, etc as just like roads. Who maintains your roads? Anyone that provides a service using those roads can do so without disruption, and the entity that owns them maintains them and permits access. They generally have no vested interest in extorting excess money out of the users of those roads, but do charge them for use. Other aspects of our infrastructure could be similarly maintained and we would solve the 'local monopoly' issue while minimizing disruption.

So make all ISPs utilities then (most of them built their lines on the gov't dime). Oh wait, you don't want that as then you wouldn't be paided to shill for them anymore. Tough shit, get a real job parasite.

Future of Cars: Hydrogen Fuel Cells, Or Electric?

sfcat Re:Average price of new car = $31,252 (659 comments)

The average American doesn't even spent $30,000 on a car, so the price range of these new vehicles is still in the realm of the rich for toys and games.

The average price of a new car in America is $31,252. A $40,000 vehicle is not remotely out of reach for a large percent of the population.

A Volt is $35K - tax credit ($7.5K to $9K depending on the state). So the actual cost of buying a Volt is less than the average cost of a new car.

Future of Cars: Hydrogen Fuel Cells, Or Electric?

sfcat Re:Electric. (659 comments)

^ This...

I only need 50 miles a day of range almost the entire year. But about 5% of the time, I need 300+ miles of range with the ability to "recharge" in 15 minutes.

Owning a single vehicle that does both tasks costs less than buying two vehicles. It also costs less than buying the EV and renting a truck for the road trips, we don't really have in place a system to do that well, and frankly I don't want to take someone else's beater rental vehicle on a family road trip, I want to take MY vehicle on a family road trip.

A Volt does this now. Quit making excuses...

Future of Cars: Hydrogen Fuel Cells, Or Electric?

sfcat Re:Electric. (659 comments)

While you are correct in the sense that if you drive enough, the savings of not buying fuel do add up...

The use case where that is true is narrow...

There are plenty of very efficient small cars that can be purchased for $10K+ fewer dollars than the Volt. Over 5 years of ownership, you'll be hard pressed to burn $10K in gas in a small 4 person car over the cost of recharging a Volt.

Add to that the resale of a Volt in 5 years is likely to be terrible as they keep dropping the price, it makes for an even worse investment.

It may well get there, but the people pushing for it today like to ignore a few details that explain why EVs are hardly a rounding error in vehicle sales.

It isn't because people want to waste money, it is because people have done the math and it makes no sense, unless you're "a true believer".

Riiiiiiiiight, so that bargin $15K ICE car is never going to need maintenance? I have a Volt and my maintenance cost is 0 so far for 2 years. I doubt I will reach the first scheduled maintenance (which can be at 75,000 miles depending on usage patterns) and is just an oil change for the generator which can easily be done myself for $10 in oil. The parent said its about COST, not price. Costs like maintenance that EVs don't really have in practice are not free for ICEs. EVs are cheaper for 90% of drivers daily usage patterns at this point. Not some minor slice of the market, but most of the market. You would have to drive less than 1000 miles a year for an EVs to not to pay off at this point. You are just considering gas costs, but maintenance costs can easily exceed gas costs, especially for cheaper or older ICE cars. Plus the time I don't spend waiting at tollbothes (yea HOV lanes). Just make sure not to lease the Volt as you don't get the $7500 federal tax credit that way.

Future of Cars: Hydrogen Fuel Cells, Or Electric?

sfcat Re:Electric. (659 comments)

Range is the issue.

My commute is 40 miles each way. What EV do I buy that ensures me I can get to work and back home on a single charge, accounting for common traffic jams and problems that causes for actual range, and accomodates the lack of charging slots at work?

It would be OK if I paid less than a 30% premium over typical retail price, even better if I pay only a 50% premium over the typical price of a 5-year-old used vehicle, though I generally drive 10-year-old vehicles. I know, that rules out lots of vehicles.

Electric is still not for me.

A Volt would cut your gas usage in half, and if you have charging at the office, then it would be probably 90%. And its $26K after tax credits. Quit making excuses, your choices are about you and not about the EVs available anymore if you can afford a new car. If not, then it will probably be another 3-5 years for you.

All reasonable points...

Offer the Chevy Volt for $20K and they could sell half a million of them a year...

At $35K, it is a non-starter...

It begins and ends there, all other arguments are really academic...

Its $25K after the tax credits. Quit making excuses...you sound like the ranchers in TX that pray for rain as they deny Climate Change.

sfcat Re:And he's the only one? (311 comments)

Doesn't mean that CA companies don't try to get you to sign Non-competes all the same. Of course, I've signed many documents over the years working at different startups that I knew couldn't be enforced against me. On more than one occasion, I've told the person asking me to sign, "Of course I'll sign this, there is no way it would ever hold up in court" and then told them here are the CA statutes you are violating and why this contract is worthless. Oh, and BTW, I've changed my mind on the salary, its now $20K/yr more because you don't know how to hire a good lawyer and the expected value of those options are basically 0 because of that. Shockingly, I've had some startups actually pay me the extra $20K...the others I just turned down and soon after found a better startup. Frankly, if a CA startup asks you to sign a non-compete, run simply because that startup is almost certainly going to fail.

Headhunters can't tell anything from Facebook profiles

sfcat sfcat writes  |  about 8 months ago

sfcat (872532) writes "Companies, headhunters and recruiters increasingly are using social media sites like Facebook to evaluate potential employees. Most of this is due to a 2012 paper from Northern Illinois Univ. that claimed that employee performance could be effectively evaluated from their social media profiles. Now a series of papers from other institutions reveal exactly the opposite result. “Recruiter ratings of Facebook profiles correlate essentially zero with job performance,” write the researchers, led by Chad H. Van Iddekinge of FSU. Not only did the research show the ineffectiveness of using social media in evaluating potential employees, it also showed a measurable biases of the recruiters against minorities (African-American and Latino) and against men in general."
