Neglecting the Lessons of Cypherpunk History

YesIAmAScript Re:TFA Misunderstands the History (103 comments)

"when it was revealed that the NSA had actually, and pretty amazingly, undermined hardware random number generators on widely available chips"

Such a thing was never revealed.

https://www.schneier.com/blog/...

"I have no idea if the NSA convinced Intel to do this with the hardware random number generator it embedded into its CPU chips, but I do know that it could." (could meaning it is conceivable here, he doesn't investigate anything about feasibility)

No one ever showed that the NSA did this. No one even tried.

It's really frustrating to see speculation reported as truth from a person who seems very careful to try to be sensible and not just ring alarm bells to get notice.

How Sony, Intel, and Unix Made Apple's Mac a PC Competitor

YesIAmAScript Macintosh 100? Terrible article. (296 comments)

There's no Macintosh 100.

There were two Mac Portables before the MacBook 100/140/170 came out.

Indeed both were enormous, each even had a lead-acid battery! The first one didn't even have a backlight.

The Sony-designed MacBook 100 was actually designed to just be a smaller version of the original Macintosh Portables, which is why it also was based upon the much slower 68000 processor (the 140/170 used 68030 processors).

The Powerbook 100 was well designed and small, but it wasn't really a big seller. The PowerBook 140 and PowerBook 170 took most of the sales. The later Powerbooks (145b, 160, 180, etc.) were all nearly identical to the 140/170 and not Sony's 100. This seemed to show that Apple didn't really take all that much from Sony's PowerBook 100.

Assange: Google Is Not What It Seems

YesIAmAScript claimed threat (289 comments)

Under a claimed threat of extradition to the US.

There's no actual evidence of it and in fact extradition from Sweden is harder than from the UK.

Let's not forget that Assange is where he is by choice. He says he fears extradition to the US, but there's a lot of other possibilities too. He may just simply fear conviction.

Will Fiber-To-the-Home Create a New Digital Divide?

YesIAmAScript Re:DOCSYS? (291 comments)

That is not at all true. A single fiber cannot handle the world's internet bandwidth. And the PON systems used for homes don't even dedicate 1Gbit to each termination (house). You don't have a dedicated connection to a chassis with 2,000 other customers, you are PON split from a single fiber with a lot of other houses, then that goes to a chassis.

"It doesn't matter how it is shared as long as there is no congestion." is a useless truism. It's true for copper too.

I think it's hilarious that you think that your ISP is only oversubscribing their links 2x (2,000 1Gb connections to 1Tb backhaul). That's fantasyland at the prices that residential customers pay.

The Great Lightbulb Conspiracy

YesIAmAScript your washer has a cycle time? (602 comments)

This is crazy. Just because the service tech told you something doesn't make it true.

I have an HE washer/dryer that predates yours. I got it them 10 years ago and they're still going strong. It was the Maytag Neptune, which was the first HE washer on the US market. There was a flaw in the door latch on the first year or two model but I was lucky to avoid that, mine is from just after that.

The washer works fine, although it is nice if you leave the door open for a day once in a while to dry it out in there otherwise, since the door is sealed, any moisture left in the drum after a cycle just sits there until next time you use it. It doesn't have anything to do with hot water, hot water only stays hot for a short time and hot water doesn't kill mildew anyway, if it did you wouldn't need to scrub or bleach the grout in your shower! Later models from Samsung and LG don't have this problem.

The dryer doesn't even have cycle times. It just runs until the clothes are dry. It does this using a dryness sensor, the same type which has been around since 1980 or so. If you do run it on a timed cycle, you can adjust the time it runs in one minute increments. So I have no idea what your tech was telling you about mandating short cycle times or burners that aren't hot enough.

Apple Edits iPhone 6's Protruding Camera Out of Official Photos

YesIAmAScript it's simple math, similar triangles (425 comments)

On the smaller phone (iPhone 6) the lens is 50mm from the far (button) edge of the phone and protrudes 0.8mm. The phone is 7mm thick.

Thus there is a triangle formed on the top of the phone which is 0.8mm tall and 50mm base. Now, if you make the triangle 7.8mm tall you form a triangle with the front plane of the phone, a triangle with a base (7.8/0.8)*50 of 487mm.

So if you take the picture from less than 487mm away (half a meter) you can take a picture which doesn't show the camera and doesn't show the face of the phone (thus is "edge on") without using any photoshop trickery. The phone body will simply block the camera from view.

And that's surely what Apple did. It's not hard to do.

Also note: you don't have one, troll. It doesn't come out for a couple more days.

If Tesla Can Run Its Gigafactory On 100% Renewables, Why Can't Others?

YesIAmAScript same junk as last time (444 comments)

You cannot base any real analysis on figures take by looking at an artists rendering of the site.

The article says that they will have 85 windmills because there are 85 windmills in the picture. This is garbage. It is an artists rendering!

If you want to have a serious discussion, you have to wait until there is some actual real info to discuss.

Note that net metering is not running your plant completely off renewables. It's running it off renewables some of the time.

First Intel 14nm Broadwell Core M Benchmarks Unveiled

YesIAmAScript work/Joule (51 comments)

or MIPS/Watt.

work per Watt makes no sense.

work/Joule is how "cheaply" you can get something done. MIPS/Watt is how fast you can get something done given a restricted power supply (or power envelope).

Tesla Plans To Power Its Gigafactory With Renewables Alone

YesIAmAScript Re:batteries cost money (260 comments)

I forgot to do the 30% part.

2900MWh times 61 * 0.3 or 53GWh, 53M kWh. 530,000 packs or $2.66B worth of packs (apparently I misplaced a decimal point before). 1 year of entire plant output.

A lot closer to workable, but still unworkable.

This is why grid-scale electricity storage is considered a nascent technology instead of a solved one.

Tesla Plans To Power Its Gigafactory With Renewables Alone

YesIAmAScript batteries cost money (260 comments)

And those batteries cannot hold a charge for 6 months anyway.

Even if they could, you're talking about a deficit of about 1/3rd at the peak of winter and a corresponding surplus in the summer. So let's assume you have a 1/3rd total energy surplus for 2 months in the summer and have to hold it 6 months until winter where you use it up.

That'd be 2900MWh times 61 or 177GWh. that's 177M kWh. A Tesla pack holds 85kWh, let's assume it's about to become 100kWh. And the pack costs over $10K, we'll assume it costs $5K.

That would mean they need 1,770,000 packs, at $5K a piece or $89B worth of packs. It's also the entire output of the plant for 3.5 years.

Does this seem workable to you?

I think you're not getting a good grip on the actual size of the problem.

Tesla Plans To Power Its Gigafactory With Renewables Alone

YesIAmAScript Re:Musk worship (260 comments)

> Is it getting major tax breaks?

Yes. It's getting huge tax breaks here. It got a nearly free auto plant from California.

It gets $7500/car in subsidy from the feds. Many states give $1500 to $5000 on top of that. Some countries they sell into give tens of thousands equivalent.

And this is beyond the emissions trading money it gets, which is a subsidy, but not directly from governments, just enforced by the government.

>becasue they are high end luxury vehicles. Do you send letter to Mercedes telling them their care a rudely expensive?

If they charged $90K for a car which is luxury equivalent to a Hyundai Sonata I would. It's a nice car, but it doesn't measure up to other $90K cars on luxury.

Tesla Plans To Power Its Gigafactory With Renewables Alone

YesIAmAScript "some storage" (260 comments)

From the article:

"Reno gets an average of five peak sun hours per day."

Remember, as soon as you say the word "average" you are counting on a huge amount of storage so that you get the average amount of energy every day, even if that day is below average. And even if every day for the last two weeks has been below average.

In in fact, if you are using solar, you have to understand that nearly every day between the autumn equinox and the spring equinox is below average. That means you need enough storage to store up electricity all summer so you can use it in the winter! This is not at all realistic. More realistic is to make sure you produce more than you need in the summer and enough in the winter.

This does use more than solar though. However, I can't believe this guy counted the windmills in a PR picture.

Anyway, buying and erecting a 3MW windmill costs about $10M. That would mean Tesla would spend $850M on windmills. You cannot seriously think that Tesla is going to spend $850M on windmills before the plant even opens.

Microsoft Defies Court Order, Will Not Give Emails To US Government

YesIAmAScript Re:customer-centric (419 comments)

This isn't seizing. This is ordering an entity to produce evidence. Yes, the US could order a US company to produce the contents of a safe deposit box in Europe. If the company doesn't comply, the US arm would be fined until it does comply. That is if the US couldn't get cooperation from local authorities to get it seized.

The US government isn't saying anything about other countries' laws not applying. The US government is saying its own do. Where there is a conflict, it really isn't the US government's problem, it's MS' problem.

And this whole thing works in reverse too. US companies in the EU are required to comply with EU laws, including producing evidence that is outside of the EU.

Just to wonder, if you really believe that out of the US is out of the US' reach, you must be really shocked to hear of the IRS now finding out about money in offshore accounts and taxing people on it, eh?

Ask Slashdot: What To Do About Repeated Internet Overbilling?

YesIAmAScript 2x AT&T's elite service? (355 comments)

AT&T UVerse is 26-36mbit if your system has their FTTN upgrades. And if you can get sonic.net, chances are it has them.

sonic's tech support is truly fantastic, but I can't deal with the slow speeds anymore. The upstream speed is particularly glacial.

Solar Plant Sets Birds On Fire As They Fly Overhead

YesIAmAScript NIMBYs? Crackpots? (521 comments)

California has had 2-3 of these running for decades. Yes, newer ones are bigger, but even the smaller ones like the one in Coalinga can fry a bird if it flies near the focal point.

Maybe just stop building these. They are quite expensive. They are the most expensive source of electricity, bar none.

Project Aims To Build a Fully Open SoC and Dev Board

YesIAmAScript Raspberry Pi was putting a chip on a board (47 comments)

Well, securing supply of an already existing chip at a good price and putting it on a board.

That doesn't relate to designing an entire SoC and getting it fabbed.

How Google Map Hackers Can Destroy a Business

YesIAmAScript you need to claim your business (132 comments)

Make a google account. Claim the business. go through the verification process.

https://support.google.com/pla...

And then after that they only take updates from you unless someone else can succeed at the verification process which should be a bit hard without pilfering your mail.

Netflix Could Be Classified As a 'Cybersecurity Threat' Under New CISPA Rules

YesIAmAScript it's not not an effort (125 comments)

"that may result in an unauthorized effort to adversely impact the security, availability, confidentiality, or integrity of an information system or information that is stored on, processed by, or transiting an information system."

It's not an effort (authorized or unauthorized) to adversely impact any of those things. It is an effort to deliver video.

You changed "effort" to "impact". You're changing the meaning of the sentence.

If someone were to hijack Netflix' traffic to create an effort to deny service, then that would be a denial of service attack and ISPs could counter that, as ISPs already counter DoS attacks.

Netflix Could Be Classified As a 'Cybersecurity Threat' Under New CISPA Rules

YesIAmAScript no, it's not true (125 comments)

According to the bill a threat is anything which is anything which is part of an unauthorized effort to deny access. Netflix streaming which inadvertently leads to a denial of access would not be part of an effort to deny access.

Here is the bill.
