jacobwcarlson··on Bitcoin arbitrage without market risk
Assuming input is from a benign source is literally the cause every single security issue ever. It's bizarre that I've been downvoted for this. And you're commenting about how I'm wrong without even reading the code. I seriously don't understand this site.
jacobwcarlson··on Bitcoin arbitrage without market risk
It's weird that over the course of 7 hours no one on a site called Hacker News noticed that send_email.cpp passes unsanitized user-supplied args to system(). I've spent less than 5 minutes looking at this code, so maybe that's the worst of it. But if 5 minutes of investigation found 1980's style bugs I doubt that's the worst of it.
jacobwcarlson··on Paralyzed man regains use of arms and hands after experimental stem cell therapy
This is rather odd. Knee cartilage damage is extremely common among athletes, so one would think that the treatment would be as well. But I've never heard of it used for professional athletes.

Speaking anecdotally, I've had 4 wrist surgeries over the past 5 years (coming up on my fifth next week). I've never once heard of the stem-cell injection treatment, despite having 3 surgeons and 9+ other consulting doctors. Did your doctor give you any papers to describe the procedures that made his knee "all better now"?

jacobwcarlson··on Rust vs. Go
I believe he's saying that the Rust book[0] is very good (and completely free).

jacobwcarlson··on White House predicts all truck, taxi, and delivery drivers will be wiped out
For the most part savings from labor should reduce prices and in the aggregate, "all of us" do share in the benefit. Now obviously there is no guarantee of that, but competition will likely result in a good portion of savings passed to the customer (e.g. if FedEx drops prices UPS will have to do so as well).
jacobwcarlson··on Uber’s self-driving cars start picking up passengers in San Francisco
Indeed, and I'm almost positive that I've seen models other than the C90s. I didn't realize that they were toting real passengers, though. I thought they were just Alpha Tests As Marketing. Given that they made this announcement the day after Google announced Waymo, I'm now convinced that's what they are, but I guess with real passengers?
jacobwcarlson··on Thomas Schelling has died
And Black-Scholes just codified what seasoned options traders had understood for centuries. The reason it was important and rewarded is exactly that codification, which enables rapid understanding to a wider audience.

Discovering something new is exciting and important. Explaining that discovery in a way usable by the rest of humanity is ground-breaking.

jacobwcarlson··on Magnitude 6.5 earthquake hits off Northern California coast
There is no cost-effective way to get residential earthquake insurance in the Bay Area.
jacobwcarlson··on Investigating a malware sample which sometimes fails to behave maliciously
> Interesting yes, but "novel"? I'm not sure.

It's not. And I don't know anything about SentinelOne so maybe they're amazing, but being stymied by dynamic analysis of VBScript malware seems, um, odd.

jacobwcarlson··on It Costs $30 to Make a DIY EpiPen
That's an odd slippery slope argument to make on a site called "Hacker News."
jacobwcarlson··on It Costs $30 to Make a DIY EpiPen
"Sola dosis facit venenum": https://en.wikipedia.org/wiki/The_dose_makes_the_poison
jacobwcarlson··on Malicious ZIP archives found in the AKP leak on the Wikileaks site
> So a spammy email in one of the thousands leaked happened to contained malware? And this is newsworthy why?

Because it's another example of the unconscionable lack of attention to detail that Wikileaks pays when putting out these dumps. Not quite at the level of outing gay Saudis and rape victims (putting them at risk of death), but still just very amateurish.

jacobwcarlson··on DEA will ban chemicals contained in kratom, a popular herbal supplement
I think you may be misremembering the medication. I take 1200mg of Gabaptentin/day for ulnar neuropathy; I don't think that 75mg would accomplish anything.

And FWIW I code all day long.

jacobwcarlson··on FBI says foreign hackers penetrated state election systems
Population growth in the US is approaching 0.7% annually and has been declining for 2 decades. Not sure what scaling needs you foresee.
jacobwcarlson··on Machine Learning and Ketosis
> To my utter surprise, something as stupidly simple as coffee blended with butter with coconut oil (or MCT) first thing in the morning did unbelievable things for mental productivity.

Eat food. Mostly plants. Not too much. If that doesn't work for you, talk to a doctor.

jacobwcarlson··on Crystal: Fast as C, Slick as Ruby
You could've answered those questions yourself if you actually looked into the language, but you didn't. You instead offered facile and superficial judgement. If you have complaints, state them. Speaking in generalizations just sounds like whining.

To be clear, I have no strong opinions about Crystal and will probably never use it. But comments like yours are simply grandstanding and it's annoying that they are confused for contribution.

jacobwcarlson··on What if financial systems were hacked
> The biggest barrier to entry is getting a mainframe to experiment with.

Is there a barrier to emulating these systems? It's probably difficult (illegal?) to emulate the various Tandem operating systems on virtual hardware, but I'm sure there's a way.

I'd be shocked if there wasn't a turnkey AS/400 VM available.

jacobwcarlson··on Unity raises $181M round at a reported $1.5B valuation
That's only true for NQ options. With ISO options you aren't taxed until you actually sell the shares they covert to, and then as a capital gain tax, not as ordinary income.
jacobwcarlson··on The British are Googling what the E.U. is, hours after voting to leave it
Probably the part where we can amend our state constitution with 50% + 1 on ballot initiatives.
jacobwcarlson··on uWebSockets: Scalable WebSocket server library for Node.js and C++11
There are many improvements that could be made to this code. However the developer is extremely antagonistic and unwilling to accept criticism so I doubt that the issues will ever be fixed.
jacobwcarlson··on Swift: Things I really wanted that won’t make it
It would be nice if that returned the number of characters printed, ala sprintf() in c.
jacobwcarlson··on Tech layoffs more than double in Bay Area
I live in SF and was a little surprised how many SF-based candidates responded to a front-end engineering position I posted on Stack Overflow (the position is remote and my location wasn't part of the post). But I certainly don't know anyone local who is out of work.
jacobwcarlson··on Review: Japanese Hologram Pop Star Hatsune Miku Tours North America
AFAIK Gibson's just really good at assessing culture and predicting its course.
jacobwcarlson··on Review: Japanese Hologram Pop Star Hatsune Miku Tours North America
The absence of Idoru[1] references is surprising. Almost as surprising as learning that book is 20 years old. I may need to re-read it.

jacobwcarlson··on Steam now accepts Bitcoin for purchases
> And hoarding isn't a bad thing. If you aren't spending your money, then you aren't taking resources out of the economy. That means more resources for everyone else. Spending money, consumption, is what should be discouraged.

I'm usually pretty good at detecting irony, so I apologize if I've been bested here. But are you honestly suggesting that reductions in consumption and spending are favorable to nation's economy?

If you are being ironic, I don't think I understand your message. Would you mind explaining it to me?

jacobwcarlson··on San Francisco Torn as Some See “Street Behavior” Worsen
There is no tl;dr for crime, society, and geography. Even if there were I think San Francisco would still be an outlier. Regardless, arrests and incidence of crime are separate things. Making it easier to look at data is certainly useful and thanks for helping in that respect, but that doesn't provide answers on its own.
jacobwcarlson··on Alphabet slides 5% after missing earnings expectations on revenue of $20.3B
> https://blog.pagefair.com/2015/ad-blocking-report/

Can anyone shed light on the relatively widespread adoption of ad blocking software in Poland and Greece? A cursory search doesn't indicate any particular bandwidth or cost constraints.

They lost a golden opportunity to start this with "Congratulations on your purchase of a Space X Falcon 9..."
jacobwcarlson··on SpaceX Launch Livestream: CRS-8 Dragon Hosted Webcast
"We are backed up in how much stuff we have to deliver to space" certainly seems like one of the better problems have.
jacobwcarlson··on The Financial Industry Is Having Its Napster Moment
Because drawdowns are inevitable and investment companies need operating capital even in (particularly in) down markets.

If they were paid solely based on performance then you would also pay points on the spread between what you lost vs. what some benchmark lost that year. I can't imagine many investors wanting to take on that kind of risk.
