craigyk··on The F-35’s Software Is So Buggy It Might Ground the Whole Fleet
Yes, at least in medical settings, I think it's just as much about accountability and CYA than actually improving overall real-world security. If that person's action results in a leak than they can be personally sued and fined. Doesn't matter if they did it out of frustration with obstacles that made it very difficult to "get stuff done".
craigyk··on For anyone who has been turned down by 38 companies
Thanks, it does sound like things have changed. I probably would have been a better hire back then than today though. I was younger, cheaper, and had an almost OCD drive to learn everything CS since I had a complex about getting into the game a little late. Today I feel like I wouldn't be able to maintain my current lifestyle with a wife, two kids, two dogs in the bay area. Occasionally I think about it though...
craigyk··on Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly
pumping melted, probably saline water over ice doesn't seem like a great way to refreeze the water, more like a good way to melt more ice.
craigyk··on Climate Model Predicts West Antarctic Ice Sheet Could Melt Rapidly
By my quick calculation, one meter of sea rise would be ~100,000 cubic miles of water. The great lakes hold ~5,500. So no, probably not.
craigyk··on For anyone who has been turned down by 38 companies
My Google interview in 2008, one guy asked me to write a binary tree structure and implementations of depth and breadth-first search (maybe also balanced insert?) on the whiteboard in C, which I blew through in no time. He then immediately said it was wrong and let me wither for a few minutes trying to figure out what the problem was before pointing out I forgot a semicolon.
craigyk··on Google says self-driving car hits municipal bus in minor crash
I wonder about this too. If you are new to CA, at first it seems crazy how aggressive people are about splitting the right hand lane to turn right... who would have the right of way if the bus was already stopped at a light, but the AV split the lane to turn right and passed the stopped bus? I like the idea of splitting the right lane to make right turns, but IMO, if you've done so, you no longer have the right of way for traffic in that lane.
craigyk··on XtreemFS – Fault Tolerant Distributed File System
How are the two related exactly? Is XtreemFS part of the core of the Quobyte product, or is it a dead-end, with all new development happening in Quobyte?
craigyk··on BeeGFS, the Parallel Cluster File System
I will say that I know two people that have independently tried fairly large trials (400TB+) of Lustre, GlusterFS, and BeeGFS, and BeeGFS was their eventual favorite.
craigyk··on Apple Apologizes and Updates iOS to Restore iPhones Disabled by Error 53
It's not entirely clear cut, but IMO apple was also in the right when it came to the ebook price fixing.
craigyk··on Google and Red Hat announce cloud-based scalable file servers
based on another comment. I forgot to add that I always had an odd number of servers in the GlusterFS cluster to help with consensus, even if that server did not actually hold any data bricks.
craigyk··on Google and Red Hat announce cloud-based scalable file servers
My experience was not as bad as yours, but the problems I saw at a similarly small scale (6 servers, 3 2X replica sets) make me glad I'm not having to scale up a GlusterFS infrastructure. The biggest problem I saw was with absolutely atrocious performance when healing after a temporary node loss. Even if it was just a loss of a minute or two (server reboot), it wouldn't lose availability or corrupt files, but performance would get so bad for the next 2 hours that it might as well have been down.

If I had to make a comparison, I'd say GlusterFS reminds me a lot of MongoDB in the beginning. It wins a lot of kudos at the outset based on ease of setup, management and CLI UI, plus it has a good "story" on ability to scale up that gradually begins to fray when pushed. Hopefully there have been big improvements.

craigyk··on America Is Flint
I can only say that you get what you pay for, private vs. public non-withstanding. I don't put it past any private company to put in an unrealistically low bid, and hope for one of three exit strategies (based on what I've seen in my short lifetime):

1) Bill the difference later, resulting in huge overruns. 2) Be out of the picture when the hits the fan. 3) Declare bankruptcy, all stakeholders walk away with their gains

craigyk··on America Is Flint
That's a really good point. I guess we'll see if Europe has its own infrastructure problems in 50 years or so when some of that "new" WWII infrastructure starts to get old. I would say, though, that not all parts of Europe had to rebuild from scratch. You still find WAY more 100+ year old structures in Europe than the US.
craigyk··on America Is Flint
I think a major factor is that the US hasn't been around for very long and we're coming to a point where a lot of infrastructure is coming under need of repair or replacement simultaneously. In particular instances, this infrastructure degradation has been greatly exacerbated by decisions to save money in the short-term. My personal opinion is that this is all part of a decades long rightward shift away from "big government" and willingness to pay for proper maintenance of public works. 2008 was a wasted opportunity to combine much needed infrastructure investment with fiscal stimulus.

There is no question a lot of work will need to be done over the next decade. The question is, who will do the work, and how will it get paid for?

craigyk··on Goldman Sachs May Be Forced to Fundamentally Question How Capitalism Is Working
I don't see it. Unless you mean debt subsidized growth involving inserting "internet" or "mobile" into existing things and calling them "blue oceans". I think what Goldman Sachs is trying to say is that capitalism ( in any flavor: laissez faire or mixed economy ) might favor evolution to a small number of large entrenched winners rather than eternal competition and churn.

The proposed mechanism involving transposons in GM mosquitoes is very convoluted (imo highly unlikely). It is also a red herring, the real question is whether the virus is the cause, and what the mechanism is.
craigyk··on The Fed Wants to Test How Banks Would Handle Negative Rates
The Fed is nominally independent of the government. Ideally they should be working together with the government providing more stimulus and jobs to bridge an economic slump (also doing something about student loans, as you mentioned). Unfortunately government policy is driven as much by fear and ideology as by rationality, so we are mostly limited to what the Fed can do by setting interest rates.
craigyk··on An open letter to Paul Graham
Are you on crack? In what respect does SpaceX's achievements equal large government pushes like the Apollo program, that got a man on the moon almost 50 years ago!! Or the Manhattan Project? With almost complete certainty I can say that government projects could have achieved everything SpaceX has... now wether as efficiently or quickly I'll grant is up for debate.
craigyk··on The Bonsai Kid
I'm not an expert, but the method used really depends on the type of tree. I have faster growing tree that I shape by exploiting how it redirects growth when trimmed.
craigyk··on Bitcoin's mining difficulty has increased by 41.9% over the last 30 days
At any point since bitcoin's inception there have been plenty of major govts that could have easily afforded the resources to pull off a 51% attack.
craigyk··on Yahoo investors rankle at spin-off plan, one suggests laying off 9,000
No. It is not against the law. I think it is only unlawful in the case where the company is actively up for sale.

craigyk··on Majority of Renters Are Not Saving for Down Payment: Freddie
Of course it depends on location and timing, but I sold my last home of 6 years and walked away with 180k. Discounting what we paid in mortgage over that time we probably only netted like 40k or so... but compared to the hassle and cost it would have been to rent a place big enough for two dogs, two cats and two kids I'm probably 300k richer than I would have been renting.

Just how bad is this "permanent" performance hit? Do you have numbers?

I've seen pools that have climbed above 90%, and maybe they've suffered permanent speed degradation, but they still run fast enough to mostly saturate a 10GbE connection, so... not a problem for me?

craigyk··on Increased intelligence is a myth so far (2014)
I disagree. I think many non-genetic factors affect "intelligence", even on a day to day basis. I myself have been able to detect noticeable and substantial variations in my faculties over these time frames. Brain-training exercises might not increase intelligence (I don't know) but there was a period of time when I found them valuable as a evaluation tool- I would do some sudoku puzzles every morning to "test" my myself that day (a very specific and narrow definition of intelligence). Even between days where I didn't feel noticeably different, I would still sometimes see a large difference in average time to solving the puzzles ( ie. as much as ~1min 30sec vs. ~5min! ).

I found the "fast" days where usually better spent focusing on specific, hard problems that had been vexing me, whereas the "slow" days might be better spent multitasking, organizing and communicating with peers to explore new ideas. I never quite pinned down how to influence these variations... though I suspect it was a combination of sleep, stress, caffeine, etc. In the end, I just roll with it. I haven't done the daily testing in a while, but I still try to be hyper-aware of which "mode" I might be in.

craigyk··on The Culling of the Herd
Big, old, "boring" companies. Academia.
craigyk··on Economists effectively assume that capitalism is unnecessary
And if you did have a machine that could optimally solve NP-hard problems, why not just switch to a centrally planned economy?
craigyk··on The problem with packaging in Python
conda is quite good. It makes a strong case to be a good general (not just Python) package manager. In particular I think the way it tries to make compiled binaries relocatable is very useful (and clever).
craigyk··on It's been 500 years since California has been this dry
Driest surface in 500 years. I wonder how long it's been since the aquifers have been at their current levels.
craigyk··on Ellen Pao Is Stepping Down as Reddit’s Chief
If you know anything about the drama surrounding her, you know she's at least an accessory to some extremely shady business dealings. Any defense of her character falls into the same defense strategies as for W Bush. Either she is of (very) questionable moral character, or she is a somewhat decent, but hopelessly ill-fortuned dupe. In either case, hardly good qualifications for being a CEO.
