Comment No, it can be practical logic (Score 1) 209

You have to be careful about letting perfect be the enemy of better. Sometimes you don't have a perfect solution to a problem, or even a good one. But you may have one that is better than what you have now. It then makes sense to go with that.

Now please note I'm not saying this is one of those cases, just that it is not political logic, but practical. If your current situation is awful and you can improve it to just bad, well that is worth doing.

Comment And it's a stupid statement (Score 1) 67

While the interconnects are certainly a very important part of a supercomptuer, they aren't the hardest part. Building a high performance CPU takes a shit ton of research and infrastructure. The barrier for entry is exceedingly high and takes a long time to spin up. You can see that with China's Longsoon processor which for all the hyped ended up being a license of a MIPS core, built on an old process technology. Building a ton end CPU is just tough stuff.

Of course then there's the other fact that there are plenty of interconnect makers that are not Chinese. The big names in high speed interconnects are Cray (US), IBM (US), and Infiniband (which is made by many companies like Intel and Mellanox). It's not like China has the high speed interconnect market cornered.

Finally there's the silliness of focusing on #1. Yes, they have the #1 computer at the linpack benchmark (which is not good at representing performance in all things). However the US has the #2, 3, 5, 8, and 10. In other words, half of the top 10. The idea that only the top spot matters is very, very silly.

Slashdot has been crying wolf since they are a geek site and geeks seem to like that kind of thing and also like new technology, no matter the cost and issues.

However there have been actual depletions of IPv4 space of various kinds. First it was that all available networks were allocated to regional registrars. Now some of those regional registrars are allocating all their remaining addresses.

That doesn't mean doomsday, of course, it means that for any additional allocation to go on, something would have to be reclaimed. That has happened in the past, organizations have given back part of their allocations so they could be reassigned. It may lead to IPs being worth more. Company A might want some IPs and Company B could cut their usage with renumbering, NAT, etc so they'll agree to sell them.

Since IPs aren't used up in the sens of being destroyed, there'll never be some doomsday where we just "run out" but as time goes on the available space vs demand will make things more difficult. As that difficulty increases, IPv6 makes more sense and we'll see more of it.

We are already getting there in many ways. You see a lot of US ISPs preparing to roll it out, despite having large IPv4 allocations themselves, because they are seeing the need for it.

Comment Because someone will do it (Score 1) 231

Either states will decide you don't need insurance if you have a self driving car, or a company will spring up that will insure self driving cars for a lot less money.

It is one area where capitalism can work. Lets say all the existing insurance underwriters charge $100/month for normal insurance based on human drivers. At that rate they can cover the rate of claims and make a nice profit. Say $20/month ends up being net profit after their operations costs and payout are factored in, and operations are another $20/month.

Well lets say that self driving cars then have a 0.01% accident rate compared to human drivers (it may end up being lower than that). That will drop their payouts by a similar amount, so from $60/person/month to $0.60/person/month. Ok but they decide to keep the price the same, just make more money.

Thing is, they'd still be really profitable at $41/month, instead of $100. Someone else will realize that, and work to steal their business. They might not go that low, maybe $80/month, but it'll happen. Then they'll try to get it back and so on and so forth.

Remember that your costs aren't just based on your specifically, they are based on actuary data of accident likeness. Sure you've had no accidents, but there is a statistical probability that you will. You are in the lowest risk group likely, but it is there. If self driving cars are much lower, rates can again be much lower.

Also, have you checked around? My rates haven't gone up in a long time. Maybe your company is just screwing you because they can, and you'd save if you took your business elsewhere.

For comparison purposes I pay about $350/6 months for $200k/$500k liability insurance on an old, cheap, car.

Which is why this is pretty stupid. H.264 is "good enough" for most things. Particularly as bandwidth continues to grow. A more efficient encoding scheme would be nice, but it isn't necessary. We can already do 1080p60 video over most net connections with reasonable quality.

So H.265 will have to be appealing not only in terms of bandwidth saved, but in terms of cost. Companies won't move to use it if they have to pay a bunch extra for the privilege. They'll just keep using H.264 and more bandwidth.

Oh, wait, you didn't need to pass a test for that.

I'm just trying to think how that would have been possible. I think back then there was a medical exception you could plead for. I didn't. I passed the 20 WPM test fair and square and got K6BP as a vanity call, long before there was any way to get that call without passing a 20 WPM test.

Unfortunately, ARRL did fight to keep those code speeds in place, and to keep code requirements, for the last several decades that I know of and probably continuously since 1936. Of course there was all of the regulation around incentive licensing, where code speeds were given a primary role. Just a few years ago, they sent Rod Stafford to the final IARU meeting on the code issue with one mission: preventing an international vote for removal of S25.5 . They lost.

I am not blaming this on ARRL staff and officers. Many of them have privately told me of their support, including some directors and their First VP, now SK. It's the membership that has been the problem.

I am having a lot of trouble believing the government agency and NGO thing, as well. I talked with some corporate emergency managers as part of my opposition to the encryption proceeding (we won that too, by the way, and I dragged an unwilling ARRL, who had said they would not comment, into the fight). Big hospitals, etc.

What I got from the corporate folks was that their management was resistant to using Radio Amateurs regardless of what the law was. Not that they were chomping at the bit waiting to be able to carry HIPAA-protected emergency information via encrypted Amateur radio. Indeed, if you read the encryption proceeding, public agencies and corporations hardly commented at all. That point was made very clearly in FCC's statement - the agencies that were theorized by Amateurs to want encryption didn't show any interest in the proceeding.

So, I am having trouble believing that the federal agency and NGO thing is real because of that.

The Technican Element 3 test wasn't more difficult than the Novice Element 1 and 2 together, so Technican became the lowest license class when they stopped having to take Element 1.

The change to 13 WPM was in 1936, and was specifically to reduce the number of Amateur applicants. It was 10 WPM before that. ARRL asked for 12.5 WPM in their filing, FCC rounded the number because they felt it would be difficult to set 12.5 on the Instructograph and other equipment available for code practice at the time.

It was meant to keep otherwise-worthy hams out of the hobby. And then we let that requirement keep going for 60 years.

The Indianapolis cop episode was back in 2009. It wasn't the first time we've had intruders, and won't be the last, and if you have to reach back that long for an example, the situation can't be that bad. It had nothing to do with code rules or NGOs getting their operators licenses.

A satphone is less expensive than a trained HF operator. Iridium costs $30 per month and $0.89 per minute to call another Iridium phone. That's the over-the-counter rate. Government agencies get a better rate than that. And the phone costs $1100, again that's retail not the government rate, less than an HF rig with antenna and tower will cost any public agency to install.

You think it's a big deal to lobby against paid operators because there will be objections? How difficult do you think it was to reform the code regulations? Don't you think there were lots of opposing comments?

And you don't care about young people getting into Amateur Radio. That's non-survival thinking.

Fortunately, when the real hams go to get something done, folks like you aren't hard to fight, because you don't really do much other than whine and send in the occassional FCC comment. Do you know I even spoke in Iceland when I was lobbying against the code rules? Their IARU vote had the same power as that of the U.S., and half of the hams in the country came to see me. That's how you make real change.

Because it is good advice for actual progress. Wu isn't a feminist, she's a professional victim. I mean that literally: She makes her money by whining about being victimized and guilting people in to donating to her pateron to fund her life. She's a developer in only the most basic sense. She has one product ever, a mobile game that is very poor quality. She has no track record for actually working to advance women's rights or gender equality. Her profession is literally being a victim.

So she has no interest in advice from actual successful women developers because she's not. Her issue isn't having lots of skill but being kept down because of gender, it is having minimal skills and then playing pretend about the source of her problems.

That's why she agreed to the Ask Slashdot. She wanted the "mean" questions she refused to answer because she can point to those as examples of "harassment" to further her cause. She's not stupid, she knew what she was doing.

However while she won't take your advice, hopefully other women will, because it is excellent.

OpenSSL has first-to-market advantage, and anyone who hasn't evaluated the quality differences will choose the simpler license. Plus there are other alternatives, like Amazon's new SSL-in-5000-lines which is also gift-licensed.

The time for OpenSSL to dual-license was when it was the only available alternative to entirely proprietary implementations. That might indeed have funded a quality improvement.

I don't know a thing about the quality of GnuTLS or the Amazon thing. I've seen enough of the insides of OpenSSL to know it's not pretty, but am not a crypto guy and this don't work on it.

Maintaining FIPS compliance did not make anything easier. It's essentially a prohibition on bug repair, as you have to recertify afterward. But the people who wanted FIPS were the only ones who were actually paying for someone to work on OpenSSL.

I don't think any of the other Free Software projects ever tried to be FIPS certified.
