Good point about taking in lunch. When I worked in an office, I always did it, day in, day out. I usually made a bit extra for dinner the night before and made a lunch out of that.

Not only is it frugal, it's usually better for you. Especially if you drink water for lunch instead of hitting up the vending machine.

The other big one is takeaway coffee ala Starbucks or similar. Yes, it's nice, but the work-supplied coffee is a lot more economical.

Friends used to snicker at me until we had a little session on the whiteboard and calculated how much their bought lunches and coffees cost per year. Just $10 a day works out to about $3000 a year, and most people spend more than that.
After that I saw a lot more lunchboxes for a while.

I had some fun with MyHDL several months ago, which lets you compile Python code (using MyHDL) into Verilog (or VHDL). http://www.myhdl.org/doku.php (Some flip flop examples: http://www.myhdl.org/doku.php/cookbook:ff )

There's nothing inherently special about Verilog/VHDL as concurrent languages--I imagine a very slick-looking Clojure module could be built as well. MyHDL let me reason about the program much more easily than a Verilog equivalent, all around the block in the cases of synchronous execution, blocking/non-blocking statements and integers ( http://www.myhdl.org/doku.php/why ). Also, (mostly) painless simulation and tests!

Though I would tend to agree that a C to Verilog system would be a step back; MyHDL makes heavy use of decorators and generators and other goodies that come from the functional programming world. C doesn't really work well there; you can hack it in but at that point you might as well just use Verilog.

Here's my amateurish website: http://textbookcentral.com.au/

Started with 1500 visits/month in July and now up to 3500 visits last month, almost entirely search engine traffic.

Even with that many visits, the fact that I've segregated the market into thousands of little ones means buyers and sellers rarely meet.

If you're interested in talking more about it, my email is in my profile.
The actual figure wasn't quoted in the article, but some quick Googling reveals an LA Times article that indicates that the MPAA's budget was $64m in 2009:
http://articles.latimes.com/2011/may/10/business/la-fi-dodd-...

If you also correct for that spurious division by 2 but keep the other assumptions, the correct figure for increased revenue should be $120m.

Needless to say, 64 is not greater than 120.
Anyway you can do it online? I'm here in north Texas and very interested.
Sure.

A friend helped land me the job in a corporate IT department (an advertised but effectively fake-competitive position, bypassed HR), plus I have a strong technical degree from a brand-name university. No portfolio or design experience. I'd like to say I wowed them in an interview, but it was really just sitting down in a bar on a Friday night, shooting the shit, and then getting a programming book to study over the weekend so I could start on Tuesday.

I was very lucky, of course, so it should be said that one size never fits all. I also think it was totally inappropriate for me to get hired. But when you're unemployed with dwindling savings and have been homeless for 2 months straight, a $45k/year internship is something you jump for, no matter how unqualified you are for it or how unfair it is that you're getting that opportunity.

I sincerely apologize for anyone who's had to read the code I wrote back then. Though, all things considered, it's probably not as bad as many of the monstrosities I see regularly in my current position.

Well maybe something like 1) upload pic, 2) show full-size pic with crop preview in browser, 3) user confirms dimensions and saves to server.
Still, you are talking about round-trip overhead.

As a counter-example, LedgerSMB is very databse-intensive but we do what we can to make sure round-trips are minimized. This means making sure that everything that needs to be queried together is queried together, in the same query.

I suppose if you are doing a lot with ORMs and the like though that may not be an option.

My monthly breakdown:

- $1000 renting a room in my parents' house (utilities and wi-fi included!)

- $50-100 my contribution to groceries and household purchases

- $50-100 transportation

- $10 cell phone (it's prepaid and I'm a recluse who prefers to communicate online)

- $100-200 miscellaneous discretionary stuff that I don't really track (e.g. restaurant meal, a new pair of shoes, a sale on Steam, yet another USB stick, etc.)

At this rate I socked away about $30k annually into my "I have no idea what to do with this but maybe someday I'll figure it out" fund. Another half that amount in pre-tax retirement savings. So far I've only watched the balance slowly shrink in my brokerage accounts.

I assure you that I do NOT have my shit together, though. You can probably imagine the quality of life I have when discretionary spending is less than 5% of budget.

Considering that you have kids and a house to take care of, I can't even begin to imagine how much of a difference that 45% "other expenses" would make. But you're really going to have to offer more details before anyone here can make suggestions on how to possibly trim some fat there.

From the header comments:

This is a replacement for the compiler heap code (i.e. "C" malloc() and

Worst case performance is 1.65 times faster and best case > 70 times.

Thanks. I found estimates of 3.4MM android tablets as of mid October [1]. Pretty dismal figures or Google would be trumpeting them. Still, I think most of my point holds -- if Amazon sells 5MM kindles they won't just have a good slice, they'll have over half the market. And if your outside the US figures are correct, Amazon will hold an even bigger slice of people who can afford and will purchase android tablet apps.

I personally dont save any money 'directly' for retirement. But I'd expect people are saving living expenses for when they can not work anymore.

Edit: Indirectly is possibly my long term investments.
To answer your question about what to do after retiring at 35? I'd probably do the same thing I do now :) thats why I don't save for retirement.

Housing cost is one of the most expensive expenses. Living several rungs down in housing than you can afford generates lots of saving. In your case, mortgage is already at 35%; tax, insurance, and maintenance are probably another 10% to 15%. That's a big chunk of your expenses.

45% on others look a lot. Can you break it up? Hope you don't have expensive cellphone plans or cable or etc.

Also supporting 3 other people with one income can be tight. Children are expensive to raise. See if your SO can work, even parttime. That would help out a lot.
You seem to be arguing this as if this is reality. What you are stating is the justification. Its the theater. The story. The reality is that there are two ways to get people to give you money.

1. Make something people want.

2. Bribe people in government to give you enough money to cover cost of said bribe, plus handsome profit, plus possibly actually making something, and then have the government force those people to pay through taxes.

I dare say that what you describe may even have been the original idea, but the facts of (2) are unarguable. Sometimes (for really big ticket items) the government official has to wait until they leave government to get the paycheck, but claim it they do.
Hmm, a lot depends on how you read the context of the list. It's always best to give the most generous interpretation, so I retract that.

I'm amused/interested in how your comment changed the upvotes and downvotes my original had. Before it was positively received (+11 at the point I checked), but that was enough to drive it down to a +1 (no, there's no grave injustice here, no one should think to re-upvote it out of some misplaced sympathy). I can definitely see how your point would nullify it, but actively driving almost a dozen downvotes? HN folks are a fickle bunch =)
I'd be careful with the last Memoize example, if current_date changes then the JavaScript function at least will return the old value still.

Memoize only works if your function is one to one (one set of inputs gives the same outputs), and you cache the result of the function for each value of the input.
Looks like more evidence for Atwood's Law: Any application that can be written in JavaScript, will eventually be written in JavaScript.

I have a couple of questions:

1. How does Liu Liu's algorithm (which I think he calls "deformable parts model") compare with Viola-Jones [1]? Any idea what the error stats (false positives & negatives) are like? In my experience [2] Viola-Jones has very low error rates. Regarding performance, I think it'll be a while before anything can come close to Viola-Jones, but this algo seems good enough.

2. Ok, this might be a stupid question, but I'll ask anyway.

Does this plugin mean that face detection can now be completely done on the client side? I use face detection in my web app [2] for passport photo formatting. I'm wondering if instead of uploading the photo (~2-4MB) to the server and processing it there with OpenCV, I can download the plugin to the browser(~0.5MB?) and get everything done right there.

[1] http://opencv.willowgarage.com/documentation/python/cascade_...

[2] http://freepassportphoto.dyndns.org/

The error rates info is from the webserver's error-log. Its very rare that I see a "No face found" error (false negatives) or get complaints that the formatted photo is all messed up (false positives).
Might be. Personally, I discovered this word some time around last week, via HN.

That depends on how they count traffic. They may double count all traffic (i.e. count traffic on local links, so the upload and download are counted separately).

Or they could count only transit traffic, in which case it would only be counted once - but they would have to make sure not to miss traffic from close neighbors.

Personally I would count local traffic (i.e. to each single computer) and record upload and download separately - including servers of course.

iOS users, at least many of the early adopters, were used to spending money in the iTunes store on music. It was an easy leap for them to go from spending 99 cents for a song to 99 cents on an app. There are iTunes gift cards in almost every retail outlet so you don't even need a credit card.

Nobody's mentioning Windows Phone. I know it's a small market share, but with most owners being Microsoft techies and less competition, it could be a more profitable platform than Android.
This man has lived.
Yeah, that part didn't make much sense to me. Say I have 5 different projects, which when developing may need 5 different sets of environment settings on my local computer.

So obviously I need something that contains and applies these settings. What makes this any less likely for me to accidentally commit that than the files they're objecting to?

Your reasoning makes sense. There's a fair amount of recent research (see "meditation" via Google Scholar) indicating that meditation does indeed reduce cortisol levels and hence that could be one pathway for its effects.

That said, mounting scientific evidence indicates that meditation also changes our brain structure in ways that have AFAIK not been observed with exercise.

For me my own experience would seem to confirm this. The benefits I observe from meditation are both qualitatively and quantitatively different from what I gain from exercise (both aerobic and heavy weights).
If it's a no-brainer, why aren't short sellers flooding the market and driving down the price to the post-lockup price?
Very few people in the high salary range have their shit figured out. Your story is all too common. Just asking for advice puts you ahead of most people.

One common hack is called the "debt snowball"; it's advocated by Dave Ramsey. The idea is, keep making payments on all of your debts, but channel any extra money you can into one of your smaller debts. Once it's gone, you get a psychological boost, and you can redirect everything that was paying for that debt into another one. So the next debt gets paid down even faster, and the one after that, even faster.
The last example also doesn't actually memoize if the result of the computation is false -- it will recompute on each call.

you can do the same in PostgreSQL with joins.

For example:

select i.* , array_agg(ROW(l.*)::text)

from invoice i

join invoice_line l ON i.id = l.invoice_id

where i.id = 1023;

This returns a single row for invoice, along with an array of tuples representation of all invoice lines. You could also use casts and stored procedure languages to convert to xml or whatever if you want.

Indeed, you can do a fair amount of processing without even hitting stored procs in Pgsql. Plain SQL gives you tremendous power in Pg. I find stored procedures add useful semantic sugar around these, but especially with newer versions things like common table expressions, arrays of tuples, and the like, gives you tremendous power.
"How does this help Apache or its projects?"

The Apache Foundation is what you make of it. It will not change just because you post to your blog, but it will change if you engage the committer and membership population, build a consensus around your ideas and volunteer to do the actual work to make the changes happen.

No one will force you to do such work and if you don't want to do it, then you're not obligated to do so. No one will be upset if you, I or anyone else leaves the Foundation. It's cool. We're all here at-will, volunteering effort and code.

Apache cannot be everything to everyone, despite how much it is pulled to be so. Right now it fills a particular important role in the open source and larger software ecosystems. It's in that position due to both historical precedent as well as intentional decisions by the membership body.

But trust me, no one in Apache is ever, ever completely satisfied with the Foundation. That's to be expected -- the organization is driven by the compromises of a large group of people with different ideas and expectations. To balance between the chaos of constant change and the death of no change, the organization has grown guidelines and rules from the collected wisdom of its membership. This gives us at least some framework by which to evolve.

As for hosting code, there have been proposals at time for Apache to push the code hosting to some other organization. Once it was SourceForge, then Google Code, now Github. Of course, it's a tricky situation as the Foundation has particular requirements and wants to know its code will be around for decades. Moreover, infra team is constantly understaffed and thus are a very, very conservative bunch. We've seen way too many people jump in with a great idea and then leave maintenance to someone else. They're stubborn for a reason.

And perhaps Apache and Github are incompatible. So what? Github is a tool. It's incompatible with lots and lots of organizations and ways of doing things. The FSF has its rules and culture. Same with the Linux kernel, distros and desktops like KDE and Gnome. Android is different too. Not all of those mesh with Github and that's fine.

Probably because for the sorts of applications dbaas implementations target, PostgreSQL dominates the market among open source solutions.

MySQL is very popular on the web site, but as a database serving multiple applications from the same db, PostgreSQL has been the de facto choice in the open source world since I have been working with db's (at least the last 12 years).

Uh, I linked to the official git repos for Apache. Apache isn't afraid of git. Plenty of Apache people love git. At the same time there are issues with implementing and supporting it by the ASF infra team. If you want all those details, search those mailing lists.

Pretty much everything is outsourced to software development firms when the government does a tech project. So, 1. there's little direct management and ownership, and 2. the specs designated in the RFP may not actually be what is best to actually achieve the objective. Having actually worked on such a project, the layers of management are really a hindrance. Outside management consultants are hired to manage technology consultants who manage software development teams that are hired from software development firms... that sort of thing.

There's probably a mess of other reasons too.

I don't understand why this response is "depressing" and characterizing the reply as "about git" is, frankly, not representative of the post I just read.

Because you act as if a "fork" is a drastic choice, when the reply calmly explained that "fork" doesn't have to mean "hey, let's create a new project and try to poach users into abandoning the original one".

The answers seems to be frank, and based on having absolutely no knowledge of Apache, maybe an appropriate one. It seems like they have a process that works for them, and they are quite interested in continuing with it. And that's fine. For people who want a more (for the lack of a more succinct way of expressing it) Git/GitHub style project, they can fork it and hack away to their hearts content.

That doesn't preclude upstream adoption of code, and it doesn't preclude discussions of improved workflow within ASF.
yeah, I'm not a fan of using environment variables. Using symlinks has always seemed more stable to me.
