Comment What is it useful for? (Score 1) 109

Having a hard time imagining the use case for this.

For consumer gear, almost any SSD sold today will be faster than someone would ever need. Just use that as a cache and save some money.

For pro/enthusiast gear, money would probably be better invested simply getting more RAM -- with 32GB, in many cases I have 20GB or more of that being used as a filesystem cache. Cache tends to very rapidly exhibit diminishing returns, to the point where I doubt I'd even notice an extra 32GB sandwiched between my RAM and SSD.

Maybe as a non-volatile cache for large bursts of writes?

I'll second KeePass. Not just because it's what I use, but because it takes serious measures to protect your data. Anyone can make a functioning password safe, but the way KeePass does it shows it was designed with an eye toward security. As a dev, I can appreciate it.

A browser extension? Really? Your OS has a massive, old, reliable security feature in that one process can not easily access the memory of another process, and you choose to not use that and instead build support directly into the largest attack vector on your PC, the browser?

>60MPH in San Francisco is going to get you some pretty bad fines most of the time :).

A friend of mine Ubers in SF, and tries to do runs to and from SFO for maximum money. He doesn't live in SF either, but commutes a long way every weekend to work there because the money is so good.

>(1) You're assuming all miles and hours are 'billable', while in reality you would be driving empty towards a pickup and waiting for the next pickup.

There's a pickup fee which offsets this, and in reality you can usually chain together rides.

Also, there's an additional bill per minute if you are in traffic.

>There are plenty of people who haven't figured out how much money they're going to end up spending on vehicle maintenance as a result of all that extra driving.

The IRS mileage rate is supposed to be an average cost for operating a vehicle. It is 53.5 cents per mile. Uber pays about twice that per mile in San Francisco. So if you can go at 60 MPH you'll be making about 30 bucks an hour, which is not bad for unskilled labor.

Cheap laptops (barely more than the price of netbooks, and eventually cheaper and better spec'ed than netbooks) killed it.

Both you and TFA are wrong. Manufacturers killed the netbook because once enough of them joined the fray and started competing, they eroded their margins so much that they forced the market into "chromebooks" or otherwise gimped netbooks that were cheaper to license.

Start with some practical code/app samples that demonstrate clear trouble. Ask them to participate -- see if they can solve the trouble. Then show how the original dev got themselves into that trouble, and the "professional" thing you would have applied to avoid it.

Bonus points for going comedic with examples that are ridiculous to the extreme.

Comment Re:64-bit (Score 4, Informative) 195

It's 2017 and Visual Studio is still 32-bit.

Unless you have specific use cases 64-bit doesn't always mean better. Most apps don't need the extra address space, and jumping to 64-bit means doubling your pointer sizes, which increases memory usage, reduces locality, and puts a larger burden on cache.

In VS's case they did the math and 32-bit was better. They've said this for years now. It's not a bad thing.

> I doubt very much that I could come up with a function to balance a tree out of the blue with no prep or review, nor is there much real world need for most developers to do so.

He didn't have to balance the tree, he just had to check if the tree is balanced.

Pretty easy to do with DFS (which the DHS agent obviously knew):

int depth_check(Node *n) {
    if (!n) return 0;
    int left = depth_check(n->left);
    int right = depth_check(n->right);
    if (left != right) throw exception;
    return left;

You could probably simplify it a bit more and use unsigned ints for correctness, but this was off the top of my head.

The calling function would check for an exception being thrown, and return false, otherwise return true.

Most people spend more on their phone. Or on food. Or vacationing. This is just another form of entertainment to budget for, are you really too myopic to see that?

For people who want to use VR, or who have a 4K screen, or have a 144Hz monitor, you literally can't get by on anything but high-end. Display tech is outpacing graphics cards right now.

>You're getting a lot better living for the $150k, you're definitely not in the same boat. That's like the people who say, "Oh, my BMW payments are so high, they're forcing me to cut back on my quality of life."

You forget our wonderful progressive tax system. A person with $150k in income and $100k in expenses will also be paying $32,000 in federal income taxes a year, plus state taxes, plus medicare, medicaid, etc. Will effectively be poor.

A person with $200k in income and $150 in expenses will pay $46,000 in taxes plus everything else, and will be running in the negatives every year.

>And even in the Bay Area, you can buy a nice house for $150k a year.

So a $600,000 house? There's exactly four 3 bedroom houses for sale at the $600k price point in San Francisco right now (on Zillow). The average is closer to a million for a single family home. There's a couple elsewhere on the penninsula and Marin, but pretty much everything with these specs is going to be Oakland, Richmond, Hayward, or Concord. I'd rather live in San Diego, thank you very much. (And I have indeed lived in both cities.)
