5 Strategies for a Successful Entrepreneurial Life
So play around with the price a bit

Previously, I have charged $4.99/year, $19.99/year, $1/month, $4.99/month, and $19.99/one-time is the latest price. You're right that the sample is too small to make much of... on the other hand, it is double what the tool usually makes per month.

I'm happy to experiment, my main question is: am I missing out on the bigger picture by charging for this app instead of using it to promote TweetingMachine? I'm not convinced that the target audiences are the same... but guess I'm going to have to do another experiment ;)
How Microsoft keeps taxes down by using tax havens
Says the guy who says very categorically, "Fact: way too many obvious or stupid patents are granted."

No, that is not what my argument amounts to. You should read up on logical fallacy.

(1) So what if I'm a poor inventor whose truly patent-deserving idea hasn't yet made money and gets copied by a rich megacorp before I can. Your solution protects the rich, not the risk-taking inventors, the latter being the reason we have patents.

(2) You beg the question.

(3) The USPTO received 500,000 patent applications in 2010. Have you ever read a patent? Do you realize how specialized they one are? You have to be an expert in the field to be able to discern what deserves a patent and what doesn't, and even then it would take one weeks if not months to truly understand the proposed patent and all prior art to render such judgement. The USPTO would need an army of 10,000 (one week per patent) to 100,000 (2-3 months per patent) experts on staff.
In the wake of the bombing and shooting spree in Norway last week, some nations in Europe are now calling for increased Internet surveillance as a possible preventive measure.

I hear these sorts of things regarding hosting all of the time. However, in my experience, if you are working on an app that is large enough to warrant using a framework like Symfony or Zend Framework, you are probably going to also be using your own server. People don't build large expensive applications and then deploy to GoDaddy or something :)

Only for testing and random surfing when I got too many tabs on Chrome and FF at the same time.
Chrome is still to deep in my heart... and it got it's place after kicking FF off there, so i think opera's nice interface will stay off for a while they still have some work to do to get a bigger piece.
> It is easily the worst browser with respect to Canvas performance.

I thought so too, until I added Math.floor(x) to positions in drawImage().

When you give fractional positions, Opera takes it literally and does rendering with costly anti-aliasing for subpixel precision.

Once I rounded the numbers, Opera turned out to be the fastest.
In this case, it actually seemed to solve it. A lot of the older lisps died off as a result of CL. Scheme and Dylan were really the only survivors for a while. IIRC.
I wish I was surprised. I bet the shipping is calculated via Javascript and people with Javascript turned off get free shipping too. Intro to CS courses don't think they have enough time to get into the details of what code runs where and who and what you can trust and what encryption really does and why "oh just use https" doesn't solve everything, but it's one of the most important topics that everyone exposed to a bit of programming should know and consider. If a rewrite proxy can give your customers free stuff, it's somehow at the same time both just unforgivable yet almost expected/par for the course. I wonder how many sql injection and cross site scripting holes are in the same site.

It's somehow worked out for the incredibly fragmented Android environment. Their method of creating images that specify which parts of themselves can be safely stretched (NinePatch, http://developer.android.com/reference/android/graphics/Nine...) is a pretty neat technical aid for that situation.
It's awkward anyway. The four BBC channels and some others are all available on cable here yet iPlayer can't be used because of geographical restrictions. Such nonsense.
Opera is one of those things that I have really tried to like, but that just never really caught on. It's like when you are picking a movie: that intellectual foreign movie has been in your queue for a week, but you are tired so you just grab the nearest retarded Michael Bay movie to relax.

The few times I used Opera I really liked it. I think the guys behind the browser are very innovative and it's a shame that they seem to be always running behind on standards compliance, causing all kinds of problems in daily usage. I have to admit that it has been a while since I last gave it a chance, so maybe things have changed. Right now, there are plenty open source alternatives that are simply better.

I meant not so big a deal as transmitting the card data in the clear, and not that hard to fix, and possibly not even indicative of developer incompetence if they knew about this issue (which may be a limitation of the gateway the merchant insisted they use) and apprised their client.

Yes, it's bad for people to be able to change the prices on what they're buying, and potentially it's a very big deal if there's no reasonably attentive humans involved anywhere else in your process. (If I got a $10,000 order, I'd double check that everything was golden in my gateway before I popped the cork on my champagne.)

The worst case for this is someone with a stolen credit card purchasing big ticket items for a small enough amount that it doesn't trip any alarms. You'd be a fool to do this with your own card.
I disagree.

Why should x-1 for x==0 be undefined for a signed type? The signed type can happily represent -1. Rather, x-1 is undefined for unsigned types because those have no representation of -1.

"But I liked manual memory management."
Opera may have rich functionality, but it's done with very little code footprint:

Opera's Mac executable is 22MB, Chrome's is 57MB! (in their private frameworks, both i386-only)

Opera adjusts RAM usage proportionally to amount of RAM in the machine, so if you have several GB of RAM it might look large, but it scales down to 512MB machines. RAM usage is mostly DOM cache for fast Back button.

Functionality like Mail and RSS used to be in a 200KB DLL on Windows.

Actually I think there are a lot of parallels with eBay. I remember the very early days of that service, when there was a lot of interpersonal communication, transactions were friendly, you could send personal checks without raising an eyebrow, etc. When it became mainstream, all that went away very quickly.

I remember the first time I got screwed on an eBay transaction I thought it was just a random, unfortunate thing -- "well, I've been using this a lot, I guess it was bound to happen." Then it happened again. Pretty quickly I realized that things were going downhill, and the trust I'd put in other users of the service was no longer reasonable.

I think that's the direction that AirBnB is headed, unless they take steps to intentionally restrict their growth and remain in a niche market. Eventually they'll have to do what eBay has done, and make the transactions as anonymous and automated as possible, and probably push all but the big commercial operations (who can absorb the fraud risk that gets pushed onto sellers) out of the market.

But the upside is, I think there's a market for services like AirBnB that are still niche. As AirBnB grows and becomes less and less pleasant to do business with, and as the risk involved in every transaction grows (as it did with eBay), there's an opportunity for someone to create a competitor that's tailored to a specific niche market. Or maybe one that's built on top of a social network, so that you're always renting from a friend of a friend or something. There are a lot of possibilities I could imagine.

But AirBnB seems to be going for mass-market adoption and I think that's the death of a friendly, trusting community if it involves money.

I was not able to use Opera at work for years because of lack of socks proxy support. With each release I would download Opera, install it, check that it still doesn't have socks support and gave up.

Using SocksCap or FreeCap for that was just annoying.

After some time I stopped caring about Opera. Now, I don't even bother to test on it.
For once I totally agree. You must also add, that the vast majority of people are price sensitive and do not really care if they use an Apple, Samsung or HTC device. A lot of people around me bought the iPod (not iPad) because they were the cheapest and nice looking at the same time.

Look around you at people having a decent normal job, kids, a house to repay, etc. At the end of the month, not a lot of money left for the high end Apple stuff. These are not even the majority of the people.

In Europe, basically you have 30% of the people paying no taxes because no money, 30% with money but in fact nearly nothing left at the end of the month and 30% with extra (here I am generous).

The iPhone is selling good in Europe only because it is subsidized by the mobile operators.

So, if you continue following this line, this means that at least in Europe, Apple will simply not be able to grow past the 30% mark if not subsidized by the operators.

Then you hit the last problem, the iPad is seen as a "big" iPhone by people. They use it in addition to a normal computer and buy it with a contract.

Now you have Apple, depending for 60% of their income on hardware which most of the time requires the help of the mobile operators to be sold.

This is not an easy position to be in. I do not own any Apple device, but I thank them for what they do, because they drive the general quality of the smart phones up.
It is categorically false. Police have radios, backup units, plainclothes units, dogs, helicopters, and some level of support from just about every citizen on the street. Where this happened, you are smack in the center of Cambridge in broad daylight with hundreds of witnesses and nearby patrol units. You can't outrun every witness on the street, or the officers summoned to the block ahead of you. It is absolutely ludicrous.

But for the sake of argument, let's assume he is the next Jason Bourne and manages to elude all of Cambridge, Boston, and MIT police on bicycle. What then? They clearly identified him on the street, so he knows they have his face. They also have his prints from the laptop, and the FBI probably has those filed from the PACER incident, so pulling his complete identity is only a matter of time. Staying at his job and place of residence is therefore out of the question. Does he pull a Whitey Bulger and go into hiding in some remote corner of the US? Give up contact with everybody that ever knew him and change his identity? Even Whitey got caught after 17 years, how long do you give a mild-mannered 24 year old with no ties to the criminal underworld? "Running faster" is only putting off the inevitable and adding charges to the docket.

> it's a shame that they seem to be always running behind on standards compliance, causing all kinds of problems in daily usage.

It feels a bit to me like you're reiterating a myth. I've used opera for 5 years and I've never run into this, afair. I virtually only get problems when devs use browser detection and then tell me that "this site does not work on opera". I've also had problems with sites that were just only tested on Firefox (used to be IE but the short-sighted devs all switched browser), but there it didn't work on Chrome either.

Of course, this is just anecdotal evidence, but I think comments like yours are what keeps some people from trying out an excellent browser that does what you want and nothing else.

The only thing that I think really rocks more in Chrome is its super-smooth and entirely hidden auto-updating mechanism.
This sounds pretty nice. Together with an AppleTV and Airplay, it makes it really easy to watch BBC stuff on our TV, if only the AppleTV was available in the Netherlands..

CodeIgniter is a fundamentally PHP4 system that is, today, wedged into more modern PHP5.3 programming practices. Personally, I can't see a good reason to use CI today (and I say that as someone who has used it extensively in the past--my capstone project at school was based on it!). If you want something CI-esque, you're better off looking at Kohana...but Kohana seems to give short shrift to certain important aspects, e.g. security is something of an afterthought.

Symfony2, on the other hand, can be pretty safely termed a modern system: it's almost completely modular (and not in the "override some files, it's like magic!" method of Kohana or CI), expects modern programming practices (it doesn't treat you like an idiot; you can use PHP 5.3 stuff like anonymous functions and it's cool with it), and is blazingly, blazingly fast when configured properly.

You might try using sessions instead.
In my vimrc, I have this line:

And in my .bashrc I have this line:

alias vv=vim -S

Once you have all the files you want open and arranged the way you like, save it all and then hit \q to save the session and quit. Then, instead of vim, use vv to go right back to your session. That's how I do it, anyway.

This comment on the original post is interesting: "Fixing svn is a lot of work. You could instead write a wrapper around git-svn to make it look like svn. The wrapper can enforce a centralized workflow. The user should not be able to tell the difference."

It's a neat idea. After all, which is easier: to fix the inner workings of SVN, or to provide a more SVN-like interface to Git?

I'm using for my hobby project git, very slow learner, and it keeps me thinking if we decide to replace Perforce (P4) with git - how we are going to explain to people how it works - most of the people using it are actually not software engineers, but artists, producers, animators, etc.

Then how much HDD space we should allocate, after knowing that Perforce's own DB is in dozen terabytes.

How efficient git is with binary data. How would the team react when software engineers would work with git for the source, and the rest P4/SVN? You can't label the depot at once...

So there is probably plenty yet for SVN/P4/etc to be used. I myself fancy being cool and using git, but it's only for my hobby yet - I haven't heard of anyone using it at large in any big game development studio...
In daily use, it seems pretty much the other way around. Opera supports standards, but everyone else goes beyond them.

Also, it's about time feature detection became mainstream because whitelisting certain browsers almost always means forgetting about Opera.
