holdenk··on What you can learn from Panic's approach to email marketing
I don't think thats the site you meant (lotusapp.com is non english)
holdenk··on The Ritual Calling of the Engineer
You can get it replaced.
holdenk··on One simple API for all your payment gateways
It looks like an interesting concept, but if it truly is going to make it seamless to switch payment API providers they are going to have to store card details (assuming you don't want to store card details and you are currently storing card details on the gateway), since I don't think gateways let you dump the card details back out.

It seems like the main value proposition is you can switch payment gateway providers (or use multiple ones for say canadian/us transactions) without having to move payment APIs. If I'm really trying to avoid having to switch APIs, what sort of gaurantees do I have that you guys will be around next month?

One big concern for me is that it seems that if you fold I lose the ability to bill recurring customers unless I store CC data (something I'd rather avoid).

holdenk··on The Startup Racket
The idea that once you launch your product you shouldn't need funding doesn't seem intuitive to me. Sure writing code is hard, but there is a lot that goes on after your initial launch, and a lot of these things cost money (like sales, marketing, etc.).
holdenk··on Ask HN: Best place for business cards?
vistaprint is also ok, but the prices listed are artificially low (there is a "processing" fee).
holdenk··on Tech sector in hiring drive
Big tech companies already heavily use internships as a recruiting method for new-grads. When I went through, I remember the big 3 all paid substantially more than all of the local companies. A lot of the interns I know (including my self), returned to one of their internships.
holdenk··on Scoble and Eric Ries on how to ship software that rocks customer's lives
Perhaps I'm overly sensitive to this, but [at least the start] seems to just be making new buzz-words.
holdenk··on A real person, a lot like you
Out of interest, did you sell it? Also since your asking for CAD, I assume you are Canadian, do you mind me asking where in Canada you are from?
holdenk··on Ask HN: Best Place to Have Logo Designed?
I've had ok luck with logodesigncreation .
holdenk··on My Sites being DDosed, What can i do?
It depends on how serious the DDOS and if you expect it to continue. Switching to another host and not letting them know about your situation could result in some unpleasantness.

There are hosting providers which specialize in hosting sites which are under DDOS attacks.

Depending on your needs (shared, dedicated, etc.) you might want to investigate a number of different companies. In the past I've found webhostingtalk to be an OK community for knowledge about this sort of thing.

If you just want a name for right now, I've heard ok things about http://www.blacklotus.net/ . They do shared hosting, dedicated servers, or if you want to keep a server farm on something like EC2 they do reverse proxying (although since you use 1&1 I'm assuming that your probably on either shared or a single dedicated box). There may be better providers out there, its been a long time (thankfully) since I've head to look into this sort of thing.

holdenk··on The Apple Tablet Is Here, And It's Called the iPad
But do we know which 3G bands it supports? i.e. for American users will it work on t-mobile 3G?
holdenk··on How to sue your employer and win
While I'm loath to quote xkcd, http://xkcd.com/137/

For people like text: Essentially not doing something because someone, somewhere, who might at some point give you money might be offended is a bad idea.

holdenk··on Using temporary IPs in the cloud considered harmful
How have you measured if its done more good than harm if your doing a complete block?
holdenk··on Nexus One
I was looking at WINDs pricing, and the unlimmited only seems to be in WIND home areas, and [for the time being] that didn't seem very large.

Also, while it looks like it will work on WIND, it won't be able to roam on Roger's 3G, which seems like it would be useful until they have a more complete network roll-out.

holdenk··on Linus Torvalds for Nobel Peace Prize?
So, its my understanding, that this wasn't do the GPL versus the BSD license, but had more to do with the uncertainty hanging over the BSD distributions due to a lawsuit threat from proprietary Unix.

Now of course I could be wrong, but I think there may be other factors which could explain the difference.

holdenk··on PPK: "Apple is not evil. iPhone developers are stupid."
Its my understanding that Apple would like require an "explicit" rating, since you could change your web page to have pictures of an "inappropriate" nature.

So this doesn't solve the problem.

holdenk··on Linus Torvalds for Nobel Peace Prize?
The thing is there are a lot of GPL-like licenses. Linux might have ended up under a BSD-style license rather than a GPL license. While things certainly would have been different, I'm not convinced they would have been worse.

The assertion that there would be no open source movement without RMS is a bit difficult to believe, unless we are going for a very narrow definition of open source.

holdenk··on AIMA 3rd edition (Russell, Norvig) available for pre-order now
Any plans on an e-book of some format (pdf, mobi, azw) or otherwise?
holdenk··on Ask HN: What order to do customer signup in?
Thanks :)
holdenk··on The Crunchies Are Coming, The Crunchies Are Coming
I got a permission denied error, don't know if its temporary.
holdenk··on Ask HN: Does it really make sense to contact bloggers a week before launch?
It doesn't hurt to get in touch with them and let them know you are about to launch to give them some time before hand to prepare (if they are even interested in covering you). You can always follow up on launch day (unless they explicitly ask you not to). That being said, don't ask for a press embargo, they might write about your pre-launch thing if it sounds really exciting to them. If you absolutely can't stand that, wait until the day of.
holdenk··on Symptoms of Successful Entrepreneurs
I don't know about that. I've got a small network of friends still in school doing two different startups, and I enjoy talking to him about how its going, even though they are currently much more successful than I am (I wimped out and took a 9-5 to pay off the student loans).
holdenk··on How Bing could kill Google
Except exclusive content deals could be viewed as Microsoft using its leverage in an existing monopoly to unfairly compete in the search engine space.
holdenk··on Internet Archive's S3 like server API
A quick google search has a bunch of people indicating it is "free" and I don't see much a TOS. Is there anything to prevent me from encrypting my data and using this as an tertiary backup?
holdenk··on Comcast Internet throttling is up and running
So the problem with 7mbs at 50 with 20:1 over subscription rate is, your assuming the local loop is over subscribed (which if its DSL it isn't), and the last mile is frequently the most expensive component. As far as T1s go, those are a different beast entirely in terms of local loop costs, the standard of support, etc.
holdenk··on Microsoft Threatens Bountii for Exposing Bing Cashback Flaw
Regardless of if what the author did is deserving of sympathy, I think most of us can agree that the correct course of action is fixing the security bug rather than trying to cover it up. I mean we all know how well that works.
holdenk··on Comcast Internet throttling is up and running
Where are you getting this 512kbs for $50 per month from? When I do a quick back of the envelope calculation using relatively recent wholesale bandwith costs and backhaul costs I get much more reasonable numbers.

Wholesale bandwidth pricing isn't anywhere near that high, and back haul costs at most double it.

$10 per mbs per month isn't uncommon for wholesale bandwith pricing from "on-net" buildings (and now days $2 to $4 isn't unheard of). The back haul cost to your local C.O. is probably roughly around $10 per mbs as well (admitedly I'm going of backhaul costs from Toronto to Waterloo up in Canada) and then your down to the local loop. We will assume the cost of the local loop is allready covered in the existing price paid, so if the user wanted N dedicated mbbits it should cost N[margin][12 to 20 dollars] per month more. Now are most users may not be willing to pay for this.

A frequent way of dealing with the "bursty" nature for servers is 95th percentile billing where by you pay for the max of what you use, dropping the top 5%.

Admittedly these numbers are very back of the envelope, but I think its a bit more realistic than $50/month for 512kbs.

holdenk··on Spolsky: Does Slow Growth Equal Slow Death?
Maybe you and I are using different local Google's but for me googling for "Bug Tracking Software" both with and without quotes brings up Fog Creek in the first 5 (as of Nov/3/09). On .com atlassian is 2 bellow Fog Creek. On .ca it brings up Fog Creek right after atlassian
holdenk··on FatELF is no more. Linux developer community owned Ryan Gordon.
FatELF seems like a bad idea for Linux. The "benefits" listed on http://icculus.org/fatelf/ fail to persuade me to want to pay any additional cost.
holdenk··on IPhone Flash prototype got 30 min battery life
Well since the iPhone platform is similar to Apple's desktop platform, if I were Apple, before I went ahead and made concessions to Adobe I'd want to see some proof that they wouldn't mess up the user experience. So far Adobe has shown they aren't either willing or able to write quality Unix flash players.
