Why would you spend so much time on writing and optimizing the hand coded version of 'sum' instead of simply upgrading your version of python on that system, which would take only a few minutes at worst?

The built-in sum would outperform that loop quite handily I would imagine.
Ask HN: How do you configure environments for testing against dependent systems?
What's considered best practice when configuring test environments against dependent systems?

For example, I have a development team working on new features for my webapp. This webapp has a dependency on another system for authentication services.

Should the webapp dev environment be configured to connect to the dev environment for the authentication system? I.e.

Dev --> Dev
Stage --> Stage
Prod --> Prod

Or is it considered better practice to connect the webapp dev environment to the test/stage environment of dependent system? i.e

dev --> stage
stage --> stage
prod --> prod

Currently I consider the latter configuration to be my prefered choice as the dependent system dev environment may be in an unstable state. Connecting to stage provides stability and reliability for the developers working on and testing the web app.

What's considered best practice for this?

Zsh: The last shell you’ll ever need
My direct personal experience - as attested by the guys I work with - is that upgrading something like Python, or a browser, breaks my machine for up to a week as I fight through dependency hell.

The machine is running SuSE 8.1 with a broken YaST. Upgrading Python - I suspect - would require upgrading all the C libraries, etc. Easier just to wipe that machine and start from scratch, but why bother? This was just a trivial play on the side.
Honest question: how do you get money back from an used book over there? Around here it's unusual to sell school books when they are not needed, people I know just give them like I did so I'm wondering if it's common to sell them or if there's some program which let's you return the book for some money (which could be an interesting business if it doesn't exist yet).
Wouldn't be better to have registration optional for syncing? You could still use Read It Later without registering but only on the current platform without syncing.

Ps: If you follow this thread of logic then Apple is right, a person doesn't need to register to use the basic features of the application.

And Perl has AUTOLOAD. However the difference to these is that Io is being lazy in the examples provided in the blog post. NB. its all just messages and no commas (ie. no args).

it's not the raw skills. those have been in demand for a long time. the next big thing is going to be the marriage of analytics with intuitive interfaces. the standard model currently is pretty much power point presentations. PP sucks and yet thousands of businesses use it as the main way of communicating important statistics.
I met my cofounder in the university. We were taking an algorithms analysis class together, and were later reintroduced by a common friend. We didn't know each other very well and just jumped into it. After some initial friction, it worked out really well (you'd have to ask him if he agrees), but I think it's an exception rather than the rule. We were incredibly lucky it worked out the way it did. If I were to do it again and had to find a cofounder, I wouldn't leave it up to chance.

The biggest mistake I see is people jumping into it with friends who aren't qualified to take a company off the ground at all. Think about it - you wouldn't just hire someone because they're a nice guy without doing an interview, and the cost of a bad hire is much lower than the cost of a bad cofounder (which more often than not is fatal). So don't leave it up to chance. Make a list of qualities you want to see in your potential cofounder. Then hit up everyone you know. Call everyone you respect and ask them for a list of five people they respect. Go to university professors and ask for top five students they know. Go to events and introduce yourself to people. Do founder dating. Compile a list of twenty people you're impressed with (and hopefully are a little intimidated by) who want to start a company.

Then interview each one of them. Rigorously. Make sure they're qualified. Let them interview you (in fact, don't start a company with them if they don't rigorously interview you). Talk completely openly about your goals and theirs. Take it slow. Act as a professional - design an interview process and stick to it with all candidates. It can take a couple of months to interview and close a senior executive hire, it should take about as long to interview and close a cofounder. Do it in steps over a period of a few weeks. Define criteria and goals for each step and stick to them.

Do not wing it, or you will have wasted the next two years of your life. I'd say that if the whole process takes you less than four-six months of nearly full-time work, you're probably being way too cavalier about it (unless you already know someone you've worked with before who has all the qualities you're looking for).
Haha, that was not the thing I intended writing, thanks, will fix it right away.
That's got to be one of the most unflattering pictures of him I've ever seen. Looks like something that crawled out of 70's Star Trek episode.

I get it why he does it, he is a marketing machine all by himself and effectively does not need the publishing industry anymore, whose role has been reduced to pure marketing now that distribution has been completely disintermediated.

Personally I thought Yown was a work in progress and just _why dabbling with Io rather than a practical joke.

I think Yown got me more interested in playing with Io than anything else. However the Builder is limited (because everything gets converted to a html tag). There are more complete HTML builders for Io on github.

Bruce Tate also provides a nice example of a HTML builder in *Seven languages in 7 weeks". Below is my slightly amended version of it:

Builder := Object clone
Builder forward := method (
write ("<", call message name, ">")
call message arguments foreach (arg,
content := self doMessage (arg);
if (content type == "Sequence" or content type == "Number", write(content))
)
write ("</", call message name, ">")
)

Builder do (
html (
h1 ("header")
div (
p ("paragraph", b ("bold"), "more text")
ul (list(1,2,3) foreach (n, li (n)))
)
)
)
Don't bring that here. Invoking Communism, the Nazis, etc. is generally not a good debate tactic, and panning an entire party is especially unwelcome.

Given the fact that CA is nearly bankrupt, this seems to me to be a travesty. It may not be the absolute worst way to spend money (please don't invoke wars), but it shows a pretty flagrant disregard for the fiscal realities of things.

Do you see why people might reasonably be unhappy about this?
Twitter for blackberry
The problem with economics I see is not a problem with most economic analysis; they actually do a good job with most questions in microeconomics (to the extent that economics is the closest we have yet come to a social "science"). The problem I have is when they address what are basically psychological questions, like this article which is mostly on motivation, where their assumption of rationality is not particularly useful. In classical economic contexts, as I wrote in the original comment, people are actually about as rational as they ever get.
But then I would never have had the fun of exploring these different versions of a classic algorithm.

There's a bigger point about your comment though. I've learned through painful, painful experience to be wary of people who say "Why not just ..." It usually hides a weath of knowledge and experience that they take for granted, but which takes time to accrue. Upgrading Python might just take half a day, or it might take a week. How do I know in advance what that would be? How do I know that in the middle of it I'll still have a usable machine at all for stuff I need to be doing?

There's the old saw about stopping to sharpen the axe because, in the long run, it'll be quicker. I'm always very aware of that. I've found that trying to "sharpen the axe" by way of "upgrading" my machine always ends up costing far more time than it saved.

Your experience will no doubt be different, but your knowledge base is different from mine. There are swathes of things I don't know, don't have time to explore, and don't really care about.

In truth, I wrote the versio that blew the stack, played around for 30 minute because it was interesting, took a break, then wrote the obvious final version.

Time well spent, and certainly more fun that upgrading Python. (On that machine).
Did you read the article? The whole point is that they had already found it (or so claims the author). It's the author that just now realised.
Friends won't always have the extremely honest and frank business conversations needed. I can give anecdotal evidence of this as I was lucky to work at a record label startup founded by friends.

Both were 100% behind the company, but it took some 5 years to fully understand that 1 friend loved music (and saw the startup as a means to create the right environment for creative artists, viewing money as a side effect of that creativity) and the other loved money (and saw the startup as a means to create an environment in which to make money and viewed the creative process as a hindrance in the generation of product).

It ended quite badly, the friendship was deeply affected by this and the signings reflected a pendulum shift from creativity to product creation.

It has been argued that friendships will inhibit the asking of the kind of questions that would've rooted that out and in either scenario made it more successful, indeed that's my view of this one instance.

So yes, friendship can be a real problem.

Not that it's that black and white, friendships can also be a real boon as PG has mentioned it can be the difference that makes people stick with it through the harder times.

So there's nothing conclusive either way. Depends on the people involved.
So has everyone else. They rejected AT&T, too, and Apple's market share went from "everyone" to "just the true believers".

You might want to consider youtube traffic there, which is #4 on alexa rank. This will push the cross over by few more years for even statistical predictions.
http://www.alexa.com/siteinfo/google.com+facebook.com+youtub...

Few other interesting things to note of the alexa graph is:

- Facebook crossed youtube traffic just about an year ago.

- Google crossed yahoo traffic only late 2008, that too mostly for yahoo traffic went down hill.

- What caused the sudden rise in internet usage in oct 2009 (for all top sites sites except yahoo show a spike in traffic). Can't be early christmas traffic, guess facebook triggered this high adaption of users who spilled onto other sites too.
I've actually heard that it's also used by smaller businesses as a way to communicate with their target audience. So, for example, if you are a chain of cinemas, you can let everyone keep up with when/where you are going to release the next films. If you are a retailer, you can advertise when the new products are in.

A bit like they did in the past with email newsletters. (Though a lot better: for a start, it doesn't spam your inbox, which can remain for more important matters).

Oh, I agree about the fun part :)

But when you're optimizing something that usually indicates you would like to have your results faster! ;)

Dependency hell is one of the bigger shortcomings of the way software is distributed, my way of dealing with that is to link against static libraries or use that chroot. For most packages static linking is a compile time flag.

Typically though, compiling from source should work, it's when you start upgrading from binaries in older repositories that the trouble starts.

The Unix Haters' Handbook is worth looking up. I think it is out of print but the PDF is available for download.

My favourite from USENET is cleaning out .o files after compiling C code but fat-fingering the SHIFT key and instead of typing

% rm -f \.o

,typing

% rm -f *>o

which gives you an empty directory and a zero length file called "o"

ah yes....
The European Union has a similar set up (since each country has a different VAT rate). it's simple here. You pay VAT in the country the website is in. If the company has substancial business in another member state, they need to charge that member state's VAT for those purchases (e.g. Amazon.co.uk charges the Irish VAT rate (of 21%) rather than the UK VAT rate of 15% if you are posting to Ireland)
And now it is at -12, as you can see by looking at the total karma of -13 for this one-comment throwaway account. (Ha, I found an information disclosure vulnerability in the HN codebase ;-))
It's not so easy to undouble between youtube and google, my guess is that since youtube is a google property that it actually is a subset, so it would not make a whole lot of difference. Only those people in the youtube set that are not yet in the google set would skew that graph and hence the conclusion.

After all, this is about 'reach' and 'uniques' which translates in to people not pageviews.

Completely disregards this little thing called "domain knowledge". Maybe no-one cares if you're just building websites, but in serious software, knowing about the problem your application solves in the real world does matter, and does get more valuable over time.
No reason why blogs can't also have rules of engagement.

I have a Livejournal, and I thoroughly enjoy the discussions in the comments on it. I wouldn't bother posting if there weren't responses to the things I say.
I think it would have been easier to give you feedback if you hadn't tried to explain it to us first - that way, we could have a look at your site and give you feedback from the perspective of a new user, rather than someone who is already educated about the product.

That said, I really like the idea of being able to separate friends and family from colleagues and clients. Unfortunately, it's not compelling enough to make me and my 200 or so "friends" (and their friends, and their friends friends) on Facebook all jump ship to a new service.

Perhaps it would be better released as an app for Facebook that handles friends groups and post privacy settings for you in an easier to manage way.

(you did know, that this pretty much already exists in Facebook didn't you?)
For publishers, it's a question of semantics
Interesting bit: "vendors offer cheap solutions that enable automated tagging of metadata on content". Is that just because processing power has caught up with the promises of Semantic Nirvana that were made only like 5 years ago?
Absolutely! Fan pages are a good way to stay in touch with existing customers/fans. Often, companies also provide special offers, early bird previews & discount coupons to facebook fans. And yes, it is replacing newsletters in some ways. However, I think most firms 'play safe' and send their 'news' through everything - twitter, facebook & email. So, if you're following a brand on multiple channels, the clutter is only compounded!
This data is biased. Facebook.com is used all over the world while Google.com is mainly used in the US.

There is a google.ca, google.fr, google.co.jp, google.de, but there is only one facebook.com

So yes, the whole of Facebook will be used more than Google by just the Americans. Is it such a big deal ?

I honestly believe Facebook is on the way out.

Facebook was an elite product, it required an Ivy League address just to get through the door and established a set of middle-upper class brand credentials. Facebook is now the default, it's full of crappy games & dodgy ads. Every shitty website has a like button. It's has an irremovable reputation for a lacadasical approach to user privacy. Everyone and their grandmother are on there, FWD:FWDing Glen Beck nonsense and Farmville requests.

Every market has stratification, we define ourselves by our brand associations. There is a hole where there should be the Mercedes, the Apple of social networks to Facebook's Dell. All that's needed now is something new to come along that woos the elite and Facebook's long term fate it sealed. There's a chance it'll be Disapora but there's a very good chance it won't.

That's not to say it won't be around for years to come but it has, to used a hackneyed phrase, jumped the shark and the difference is that Facebook's value comes from it's userbase, not its services or technology. Once the top end start bailing the rot will set in fast, momentum shifts with dizzying speed on the web. I've been thinking about this for a while, I figure if I'm right, I'll be able to point to this in a year or two and smile. Not quite as profitable as shorting FB but hey, it's just speculation for fun.
Youtube vids are embedded everywhere. I'd bet a load of people view youtube vids, that may not use anything else 'google'.

I don't know if counting 'embeds' makes much sense though.
I'm a big fan of Colemak (http://colemak.com/). It took me about a month to learn it. I don't type significantly faster but my fingers move less. It feels worth it, at least.
This was a constant worry in my previous business (in the retail sector), but we did over £140,000 (GBP) of sales through PayPal over the two years we were active and never had a problem.

I'm considering using them with my new startup just for the first few months while I get up and running, purely because the setup cost is free. If I can prove the business idea works then I'll upgrade to a "proper" payment gateway.
Let's say for arguments sake I have been using qwerty for the last 23 years or so, 15 or so touch typing. How much more efficient across my lifespan can trying to teach myself a completely different layout really be? It could be years before I clean out all the errors.
Why I'm not switching ...

1. It is not a standard ... I work on lots of workstations, including machines I do not own. Context switching between Dvorak and Qwerty is hard for me

2. It is optimized for English ... I also do lots of typing in my native language too, and there is a Dvorak layout optimized for my native language, but it has differences ... and context-switching is even harder because of the similarities.

In contrast, the Qwerty layout for my native language just replaces 5 symbol keys near Enter/Backspace with the needed diacritics. All other keys stay the same ... i.e. it's just an extension of the US layout.

3. Qwerty gives me plenty of confort. I'm only doing something like 80 WPM ... I don't need more than that and it's a confortable speed for my hands (if I'm going to get RSI from that, then Dvorak wouldn't be much of an improvement)
I'm assuming you are only talking about Google's US homepage? (i.e. not including youtube and other non google.com Google properties)?
An interesting link in the context of your point:
http://www.aweber.com/blog/email-marketing/email-and-faceboo...

Note 1: check out the embedded video
Note 2: take the rest of the content with a pinch of salt; this is an email marketing vendor's blog!
For me the real question is who cares which is "superior"? Seriously, people have so many options today and they can use whatever they prefer.

I tried learning Dvorak, but at the end of the day I've been using QWERTY for over 25 years, and I can type more than fast enough.

Besides, lots of people use other layouts anyway due to language differences requiring extra keys for letters. I do want to kill the person who decided that Shift-7 was a good place for the forward slash in most of those layouts, though!
One article (or "research") rarely proves anything. This article in particular has been contested.
I frequently look for a PayPal button / logo because I'm lazy. My card details are saved with PayPal and it's easier to enter my email address and password, then click confirm than to get my card out of my wallet and type the details in manually.

As a consumer, it doesn't make a damn bit of difference to the end cost (most of the time, unless the merchant charges a PayPal Premium) and saves me time.

It's the same reason I buy most of my music from iTunes and pretty much everything else from Amazon.
