dror··on Don't use assembly unless you're an expert
Just another form of Knuth's "Premature optimization is the root of all evil (or at least most of it) in programming."

Or my personal variant Most optimizations will end up in things being slower.

dror··on Help me distribute $100,000 to new entrepreneurs in Africa
Julia,

Awesome work.

Paul, great that you recognized it and contributed.

I sometimes despair about how much negativity and nit picking there is around people who are doing, or at least trying to do, things that really change the world.

In my mind this is way ahead of Whatsapp getting all the money, yet there was very little negative reaction to that event.

dror··on A brief history of one line fixes
And C has this thing called lint that's only been around since 1979 that can detect many of these issues.
dror··on Important Kickstarter Security Notice
I have used lastpass for years, and recommend it to my friends. It's easy to use, has a free options, though I opt to pay, and is a good combination of friendly and secure.
dror··on Stop the autoconf insanity – Why we need a new build system (2003)
That's an old school build approach (it was 2003).

The modern approach is: apt-get install (or your OS equivalent).

It's 2014. I can't remember the last time I needed to install a package from source. Worst case scenario I need to add a repo.

dror··on Books to Read in a Lifetime
With a US slant and some juvenile fiction thrown into the mix.

Harry Potter and the Hunger Games, really?

dror··on An estimate of the real savings for merchants from Bitcoin
Most of these savings could be accomplished by having the merchant withdraw the payment from your bank account rather than a credit card.

Frankly, I'm surprised that Amazon doesn't offer this service. Just take the money out from my bank, offer me the same protections as a credit card, and we split the credit card fee: 1% for you and 1% for me :-).

Used to be that violated their credit card agreement to charge more for credit card purchases, but looks like that's not the case since Jan 2013. http://www.washingtonpost.com/business/capitalbusiness/as-ru...

dror··on Social Psychologists: 36 Days After a Tragedy, Jokes About It Become Funny
Looks like it was actually published on 9/26 http://www.theonion.com/articles/american-life-turns-into-ba... http://www.theonion.com/issue/3734/

Because they stopped publishing right after 9/11 http://news.yahoo.com/blogs/cutline/remembering-onion-9-11-i...

dror··on Bitcoin Ponzi scheme
This is almost perfect except for not including a warning:

"Warning, if people stop depositing money, you won't get 120% back, and you could lose all your money."

Also, it seems like the person running the site is not taking a cut. If that's right, he's not making a profit, and he's less likely to get in trouble when things collapse.

dror··on Two big announcements
We use basecamp and campfire at work. Basecamp is mediocre, not horrible and not great. Campfire sucks compared to similar tools that I've used in the past.

Seems to me that they've been successful mostly because of their involvement in the Ruby and startup world, rather than making great products. Nothing wrong with that, but it's good to be clear about the distinction between a company that makes great product and a company that's good at marketing itself.

dror··on Chronicle of a Death Foretold
At a minimum, sign http://www.change.org/petitions/president-obama-close-detent...
dror··on Confessions of an ex-TSA agent
In a funny way I find this reassuring.

After all the worries, posting from various places, TOR, and in the end from home, no one went after him even though he clearly ridiculed the TSA. It's kind of sad that we even have to consider that, but in these days of NSA abuses it's nice to see democracy at work.

dror··on The world’s rich stay rich while the poor struggle to prosper
"Your experiences of the world will cease to exist. Therefore, the only rational investment would be in life extension technologies (SENS, advanced prosthesis, etc.)."

No. You make a false assumption that everyone's main goal in to live as long as possible. Different people have different goals, and Gates clearly cares about making a major impact on other people.

dror··on Court: Google infringed patents, must pay 1.36 percent of AdWords revenue
No. Just stop granting patents on software or business processes. Copyright, yes, patents, no.
dror··on Dogecoin market manipulation?
While historically pump and dump was focused on penny stock, I wander if doing it with altcoins violate some of the laws mentioned in http://www.sec.gov/litigation/litreleases/2009/lr21053.htm
dror··on Tesla Motors’ Over-the-Air Repairs
Is there anyone that understands computer security that doesn't think this is criminal? There are so many things that can go wrong here, both intentionally and by accident.
dror··on Dear Googles: Stop asking
I gave google my phone number a long time ago when I set up two step authentication. Your account is significantly more secure when you do that. Has never been abused AFAIK.

I think of it as similar to giving identifying information to my credit card company when I'm calling them. (Though citi pissed me off asking me for the full credit card number a few years ago).

dror··on EU citizenship for sale
That's not the long run, that's just 20-60 years. Look at the US where 99% of the population is immigrants. We're not doing too badly, are we?
dror··on A living death: Sentenced to die behind bars for what?
No, that's not inevitable. That's why judges should have discretion. They can look at the outliers and figure out the circumstances during sentencing.
dror··on $4.1m goes missing as Chinese bitcoin trading platform GBL vanishes
Tulips, tulips, tulips.

Some people never learn.

dror··on Note to recruiters
You are not paying it. The company is.
dror··on How to lose $172,222 a second for 45 minutes
Is there any benefit to the market as a whole to have these high speed transactions trying to game the system?

Seems like as a rule, they're likely to cause instability, and I have a hard time seeing any benefits in them.

dror··on The cold emails which got me meetings at Twitter, LinkedIn and GitHub
The line between "cold emails" and spam is quite thin.

If you don't want me to mark your email as spam: * Do your research about me and my company and what we need. If we're a scala shop, yeah, I'd be interested, but if we're a python shop, you're likely to annoy me with your pitch for a scala product. * The fact that you're the co-founder certainly helps. * Use your company's email. Using a random gmail account makes me think that you're using it as a throwaway account. Don't even think of using hotmail, yahoo, etc. * Don't spray. If I find out that you've sent emails to 5 of my co-workers at the same time, you're much more likely to go to spam.

I've been on the other side, and these are all rules that I've used when I tried to get people interested in my products.

dror··on Tessel: The end of web development as we know it
Javascript sucks as a language but there's a huge numbers of developers that know javascript, and of the ones that don't many use C derived languages which would make it easy for them to pick it up. Another major advantage of Javascript is that it is continuously optimized in the ongoing race for performance in the browser. The node engine has been shown multiple time to be significantly faster than other interpreted languages. Finally, while young, node has a quite nice eco system.
dror··on LinkedIn sued by users who say it hacked their e-mail accounts
How does she know? Maybe while she's out the cats email or even signed up for an account with linkedin? She should install a webcam to double check.
dror··on LinkedIn Customers Allege Company Hacked E-Mail Addresses
Here's how they do it. Various times Linkedin provides me with a form to "import" my contacts from my gmail account.

This dialog looks very similar to the login form to the site. If you use the same password for both sites (I don't), you might be thinking that you're logging in, when in fact you're bringing in everyone in your address book. Not sure, if they then automatically spam everyone on your list or not.

Linkedin clearly has crossed over to the dark side since they went public. They keep reducing their free services and pushing harder and harder to try to get you to sign up for "premium" accounts. It's time for an alternative.

dror··on Nexus 4 Unusable for VoIP Calls
I have a Nexus 4. I use it with GrooveIP. I don't experience the issues described in this issue.
dror··on Mining the First 3.5 Million California Unclaimed Property Records
Someone, give this guy a medal.
dror··on Unpacking my knapsack: the privileges of a Hispanic male in tech
physics <> determinsm
dror··on Devops/Sysadmin Cheatsheet
It's too easy to have a sticky key and type sudo !1 by accident. As a rule, not a good idea to do sudo from history without examining it first. So do up arrow or CTRL-P and the edit the command.
