We spent six months travelling, starting in Europe (a proper honeymoon in Corsica, then through France and Spain) and then moving to North Africa: Morocco and Egypt.

We were travelling slowly - almost all overland without flying, and in no hurry to leave somewhere if we liked it. We ended up spending 7 weeks in Morocco because we were enjoying it so much (the original plan was just 2-3 weeks).

We would have kept going, but since the site was taking off we applied for YC from Egypt and ended up having to fly from Cairo to San Francisco for the interview - then back to Johannesburg for a pre-arranged road trip with friends.

Working on a startup while travelling actually worked surprisingly well for us. The two require different parts of your brain - startuping is very creative, while travel is very reactive. We'd go out and explore Marrakech for a few hours, talk about Lanyrd stuff, then head back to the Riad for a few hours to build things. It was actually pretty productive!

Hacking while travelling can be quite limiting though - you're carting around a lot of expensive gear, which makes some destinations / some cheap accommodation less of a good idea. We decided to put off our planned trip to Mali for a while for example.

I'm pretty glad we got out of Egypt before they turned off the internet though!
> (Single query tag lookup; naively joins the entire taggings and tags tables before limiting with WHERE)

Really? Which modern RDBMS database actually works like this when indexes are available?

Index selection and optimization is a standard feature of even the simplest relational database system. JOINs on keys with high selectivity (especially unique keys) are extremely efficient in modern database systems - in some common cases just as efficient as pulling two columns out of the same table. Subselects are something that several database systems (MySQL, for example) really suck at - but they are easily avoided in most schemas.

> Try the "when all tags match" case ($all in MongoDB), and you'll go grey a few years earlier.

Depending on your database engine, even very large AND chains can be extremely efficiently computed on an indexed column. For larger use-cases, there are good ways to avoid this problem using careful schema design.

There are legitimate reasons why relational databases aren't the solution to every database problem. Claiming issues which clearly do not exist is not a good way to get points for the other side.

It's a good list for "What you should be doing to call attention to your open-source project (when it's ready for prime-time)."

The current title reads like: "this is what you owe me if you want me to look at you." Well, ok, but I don't feel that way. I'll use smaller, humbler projects. But I do agree that in doing so I must be prepared for the day that it is no longer updated and the bugs aren't being fixed. I'd certainly feel more comfortable with projects that met most of the lists' criteria, and would be willing to bet more on them for the long haul. But I would still use smaller projects.

Some things (couchdb) seem riskier than others (php), and some very small projects (php-on-couch) seem quite risky indeed. However, I could pick up and go if php-on-couch stalled, I could probably manage if couchdb stalled, but I would be in trouble if php did.
What, specifically, is wrong with this article? That’s the important question for me. I don’t care about reading tea leaves. Siegler likes to write about Apple? So what, who cares, why does it matter? Do you really believe he should cover Microsoft and Apple equally?

There is no need to turn a harmless disagreement into a pointless attack.

This applies to Fox News and everything else equally. I will not attack anything someone says just because I think they frequently say stupid stuff.

The biggest issue I have is that they seem to have this idea of 'keep your chats open even when you're not around'; then when I open Skype on my iPhone, it downloads the last month of chat history, one message at a time, and is slow and useless (and chews up bandwidth, CPU, and battery) until I give up on it.

It's horrible design, and I can't help but think that no one at Skype has actually used it for anything, which seems improbable. I've heard that the Android version does the same thing as well. It's just terrible.

I believe he solved them both at least temporarily, but if either Egg 1, Egg 2, Chicken 1 or Chicken 2 ceases to be true for long, then the business won't survive.

Egg 1: trading lots of shares (check, tens of million shares daily)

Egg 2: track record on trading strategy that is scalable and profitable (probably was profitable then stopped once volatility disappeared or the market changed, but definitely scalable, trading tens of millions daily).

Chicken 1: Volume-based discount (we don't know for sure, but tens of millions of shares daily is enough to qualify as a high-tier class on many houses)

Chicken 2: Clients (check, billion dollar hedge fund)

Even if all this were correct, the put-downs are easily answered by the very choice of the term "cheerleader". Cheerleaders are essential to the morale and motivation of the team. The more difficult the task, the easier it is to quit - the more important their services are.

Self-aware? It took extremely blunt blog posts from the Quora review blog and TechCrunch for him to notice his behavior.

And then in the very same blog post, he still did his annoying name-dropping thing: "I woke up in Davos, Switzerland", which has no relation to the post other than promoting how cool he is.

It's worth noting that Twitter has built a lot on top of MySQL to get to the scale they're at. Take FlockDB for example, https://github.com/twitter/flockdb

1. Three months ago, a Skype customer reports a terrible, hostile, unreasonable problem with the new client via official Skype bug tracker

2. Company rep asks, “Can you provide us your feedback? You can send feedback through Skype Menu -> Provide Skype Feedback … Thanks” and provides not a glimpse of insight into why the customer is being asked to submit this complaint elsewhere instead of the rep just, you know, doing his job and getting the message wherever it needs to be, himself.

3. Customer: WTF, didn’t I just do that here?

4. Support person: “Currently, this [issue] is by design.”

5. Other users express outrage, and this is posted to HN today

6. Today, rep “rectifies” previous statement and says it is a “bug, not by design.”

(Can we get something to the HN front page about Skype for iPhone’s terrible behavior of loading all chat messages in chronological order, taking literally half an hour before the app is usable?)

The US (and probably other countries) have been visited by what he called 'extraterrestrial drones' at many of their nuclear weapons installations since WWII. They don't think the crafts are piloted by beings of any kind and they have absolutely no idea where they are from.

Though I have a hard time wrapping my head around the idea, I did believe what he told me.

Why You Should Go To Pycon
Not quite. You're thinking of payments as in money or other monetary goods. There are other types of payment and contracts that can be done that are out of the scope of goods. And that is time.

If chosen, one can make a binding contract that trades time for something. For example, I could agree to protect a friend for the rest of this life and of the next we meet for something. Gurus make similar agreements about being a teacher as well. Usually a guru agreement is binding until otherwise broken. And life usually puts us back in contact, even in other lives. Now, our relationship can (and usually does) change, but we will almost always meet them.

The show and movie Avatar the Last Airbender is very similar how the Dalai Lama is actually chosen. In the Dalai Lama's case, they are shown about a hundred objects, 3 of which belong to the last reincarnation. The TV show shows 4 objects that respond unnaturally (the 4 being representatives of wind/water/fire/earth). It is also in the Dalai Lama's case that he is also to choose people who was in his cabinet prior to his reincarnation, as there is only a few years between the death and life. This step is also proof of who he is. The search usually goes on 2 weeks after his death, in which the world is searched for his new incarnation. And in the case of the Dalai Lama, what makes his so important is that he is seen as the Avatar of Chenrezig (the Patron God of Tibet).

China is kind of capitalist, kind of socialist, and thus kind of fascist in that you have state-sanctioned corporate monopolies and industries. Same as Russia, I think. Regardless of the economic system, the one thing they're not, of course, is real democracies.

I agree, the extent to which web services are copied by the Chinese for their own market is definitely an obstacle. They've done it with so many other products, I guess this is just another one.

The point is that the anti-tivoization provision does not appear to be relevant to IOS devices. The anti-tivoization provision is to stop manufacturers of devices that ship with GPL code from using DRM to prevent use of modifications to that code. It does not seem to prohibit using DRM to lock down GPL code that does not ship with the device.

See, I’ve heard this before, but I’m

1) not sure it’s true this is the case (show me the numbers or concrete reasoning), and

2) more importantly, I believe this is a flawed approach because it’s in Skype’s best interest for users to have lots of active contacts/friends/numbers in the system. Why design in such a way that discourages desirable behavior?

It’s a failed design, and I don’t think that supposed 90% rule really applies

On the other hand, allowing potential customers to easily try your product can destroy your chances at gaining them.

Here's a quick example:

A few years back, I was writing Smalltalk web systems and evaluating which commercial implementation to use. The two big ones that bubbled to the top of the list then were Gemstone and Cincom.

Cincom offered a relatively familiar set up which would require using sticky sessions for the web server, and another backend database like PostgreSQL.

Gemstone offered pearls on a platter: shared session state across all the backends, and a build in distributed object database. I thought it would be brilliant, and reading their blogs and documentations gave no hint of any pitfalls.

Cimcom was a download away---as were any of the free smalltalks---but Gemstone then required you to contact their sales staff before playing with it. So I made a mistake and chose Gemstone, and the system was built to target their as of yet unseen architecture. When I finally got to use Gemstone, it was a mess!

If I had that experience to start with rather than just their glowing self-produced reports, I'd have never picked Gemstone and instead gone with the familiar "kludgy" system that was "good enough".

Umm... that's the bit between your local exchange (Central Office) and the nearest Bell exchange (Central Office) to where the ISP actually hosts its equipment. (In the case of the GAS, that equipment is routers that can talk PPP/L2TP, or something close, as I can't find real technical details on GAS). OK, so it is more complicated than this as there are BRAS - broadband remote access/aggregation servers - along the way that collect the DSLAM traffic together into ATM links, and the split out aggregated traffic for the ISPs. (Basically the internal Bell ATM packet network).

This is Bell's transit network. Whilst technically the UBB is on the individuals and not what is transited, it is essentially what is being billed for.

Bell is claiming that it's links on the transit network are being crippled by heavy users. This may actually be true during busy hour. But in reality this shouldn't happen, as Bell can increase the bandwidth of most these relatively cheaply, as most are fiber. There are probably a few 100 that aren't fibered, causing the biggest problem.

But OK. The more I read about this, the clearer it becomes that the problem doesn't really exist at the moment. This is Bell's way of sabotaging the GAS product that it has been forced to sell by the regulator.

I hope this is a move that will force the independents to group together to purchase their own DSLAMS and transit. And then Bell faces much stiffer competition. In the UK, BT is facing real and consistent competition, thanks to our regulator getting tough in the last few years. BT now even have to allow competitors to lease it's ducting to roll their own fiber.

EDIT: I found this:
http://www.vaxination.ca/crtc/ADSL_intro.pdf

Which suggests that the only bit that could conceivably have contention, which the wholesale customer does not control, is the connection between the DSLAM and the BAS. From the BAS's to their handoff PoP/CO, they have to pay for these "AHSSPI/AHSSL (Aggregated High-Speed Service Provider Interface/Link)" in 1gbps increments.
Clearly you have been living in a cave for the past two years; we are currently in one of the largest bank crises in history, and it's not over yet.

The definition of "anywhere particularly stupid" changed radically in the past few years. There were 157 bank failures in the U.S. in 2010, and another 140 in 2009.

Those depositors with FDIC-insured accounts did not lose a dime in these bank failures. Those who rolled the dice and exceeded the $250K limit, well, who knows what happened to their money.
