codeodor··on Experts awed by Anglo-Saxon treasure found by a bloke with a metal detector
If 1/2 goes to the farmer and 1/2 the guy with the metal detector, who is paying for the dig and what do they get out of it?
codeodor··on Is the express line really faster?
I've often felt they drop the new employees in the express lane as the reason it seems to go slower.
codeodor··on The Top 7 StartUps That Will Save The World
Sorry, I meant also to say "the slide show is under the video" and clicking on a new slide reloads the page with a different video.

It is a mess though.

codeodor··on Ask HN: Hosts you use for your projects?
There's Heroku for Ruby/Rails
codeodor··on Direct Evidence Of Role Of Sleep In Memory Formation Is Uncovered
Thanks for that. I was going to include the link to that, but when I clicked for the full text it asked me to subscribe.

Now that I've gone back, I was able to grab the PDF.

codeodor··on Ask HN: What are your productivity hacks?
I haven't yet looked into the plugin's available, but I'll check out the ones you mentioned.

I've installed PHP, MySQL, and MediaWiki from zips/installers on a Windows server I have access to so I could hit it from any of my computers or (eventually) phone.

I guess I could have set it up at home, but I don't like keeping my computers on 24/7. I'm considering getting an Asus EEE box that supposedly only needs 20W, so I may revisit that in the future.

codeodor··on Pigeon beats broadband in data transfer race
Half of the time was spent getting the data from the stick onto the computer, while only half was spent with the pigeon flying.

So, it will go up, but with quickly diminishing returns.

Based on the suggested assignments they sent out to schools, I can see how people might have been peeved about the original plans.

The Washington Times reported ( see http://www.washingtontimes.com/news/2009/sep/02/wh-withdraws... ):

"Among the activities the government initially suggested for prekindergarten to sixth-grade students: that they 'write letters to themselves about what they can do to help the president.' Another task recommended for students immediately after listening to the speech: to engage in a discussion about what 'the president wants us to do.'"

The speech as they released it Monday is a great one that I'd want my kids to hear. But because of the information about the assignments we had before hand, I wouldn't have thought it would be a good speech last week.

codeodor··on Ask HN: What are your productivity hacks?
Just this morning I've set up a wiki for myself to help with this problem.

As ideas come in, I'll post them to the front page under "free floaters" (working on quicksilver action for that right now), then as they start to form or as I do research, I'll start fleshing out the pages for each idea.

I'm hoping the wiki aspect will also force me to look at how individual ideas might be related. I'm thinking of it conceptually as a mind map that changes with time.

I'm not sure if MediaWiki has the ability to view those relationships at a high level, but if not, I'll write something that does.

codeodor··on Do hash tables work in constant time?
It seems to me he is using the same variable to represent two different quantities:

m- the size of the hash table m- the size of each element in the hash table

The 2nd m should be a different variable, and it is constant with respect to the first m, which is the one we care about.

codeodor··on Do hash tables work in constant time?
You should not be using n for the number of bits and n for the size of the input.

It may take longer to multiply 128 bit data structures than 64 bit data structures, but it is constant with respect to the size of the hash table.

codeodor··on Ask HN: Income on the Side?
Prior to the summer, I've been working part time at the local university bioinformatics lab. It's been incredibly fun and full of learning, and time consuming.

I intend to continue in September.

Other than that, I keep starting personal projects and failing to finish them.

codeodor··on Pandora now pushing radio to pay for music
The article is wrong there. But I was under the impression they pay a lot less than internet radio, based on what I've read surrounding this case.
codeodor··on Ask HN: Review our public beta for DoLeaf.com
I agree with the locality part. I'm just starting to plan for landscaping my yard, and I'd love to be able to put in my area so I could browse plants that grow well here.

I know next to nothing about this stuff, except that to have someone else do it is expensive, so it would be great to have a site to make DIY easy, along with the option to go ahead and order my plants without having to visit the nursery (of which, there are strangely very many within 2 miles of me).

That's true, but whatever they are doing, it still sounds like they've got money to spend so they are spending it. 9.5 million in 6 months? That's a lot of servers and a lot of programmers working on a web app.

codeodor··on More Proof Of Why AT&T Needs To Keep That iPhone Exclusivity
I might have guessed it based on the source, but to save you some time: this really wasn't worth reading.

It's kind of cool to see an inside memo like that, but the content is rather "meh."

TC summarizes it:

>The iPhone 3GS’s launch gave AT&T its best sales day at its retail stores — ever, its second largest traffic day at retails stores, the most transactions it has ever processed in a day, the most orders through att.com in a single day ever and the biggest features sales day at att.com ever. Oh, and it led to the most upgrade eligibility checks ever, which is not surprising at all

Who cares? Breaking records for one day doesn't really mean much. Even in a small company, (or perhaps especially so? -- say so if you think that's the case) breaking /yearly/ records doesn't mean much.

My point is that there really isn't much news here. iPhone 3GS brought us record breaking sales for one day. We sent more texts than ever the day Michael Jackson died. Meh.

I didn't do anything special to have telnet working on my Vista install. Maybe this is an edition thing?
codeodor··on The Saga Of The Bearer Bonds
Lots of speculation, not much real information.
codeodor··on Extremely simple sort algorithm with sub-cubic expected running time. [pdf]
"Usually, binary search only makes sense in sorted arrays. We show that insertion sort based on repeated “binary searches” in an initially unsorted array also sorts n elements in time Theta(n^2 log n)."

At first I thought this is unsurprising - an insertion sort being n^2 and a search being log n, of course that's the running time.

But it's not the running time that is worth of mention here - it's the fact that they are doing insertion sort while "binary searching" an unsorted array, and still coming up with the correct answer, and a sorted array.

The time complexity is incidental to the interest of the paper. In that view, the paper's title is much better than the title here on HN.

codeodor··on Extremely simple sort algorithm with sub-cubic expected running time. [pdf]
I came to say the same. What could be simpler than the O(n^2) algorithms?
codeodor··on Ash HN: I just bought a Macbook Pro, want to multiboot, now what?
When I set Windows up on mine, I could not see the Mac partition from it, nor read/write without extra paid software. The software works so smoothly I could not recall its name since I've never had to interact with it. (Having looked it up now, it's called MacDrive).

I don't know how Windows-Linux, and Mac-Linux partition connections are visible between each other without similar pieces of software.

I do know that Mac was able to see Windows just fine for reading, but writing anything was impossible.

codeodor··on Ask HN: Review my students start-up
What kind of products am I looking for?

"We could not find any products to match your search :( "

For "netbook".

codeodor··on Ask Hacker News: Online BS in Comp Sci?
Most of the jobs ads I see that require a BS also say "or equivalent experience."

But if you do go the degree route, I'm with JeremyChase - go for the MS.

codeodor··on Pirate Party Wins 7.1% of Swedish Vote, Enters European Parliament
Not sure if you're in the US, but reading your comment, I can't help but linking to an explanation of how legislative seats are dealt out in Sweden (and many other countries). It's not a thing like we have in the US:

http://en.wikipedia.org/wiki/Elections_in_Sweden#Seat_alloca...

In such a system, it's not uncommon to see a few seats go to minor parties. In the US, we'd surely see some Libertarian and Greens in congress if we had such a system. However, the US system is more conducive to 2-party politics because of the way the rules are defined, which is why we see it here and not so much elsewhere.

So, its a surprising result if you're used to 2 parties, but not so unexpected when multiparty politics is the norm.

codeodor··on California: The ungovernable state
"he voters can make policy through ballot initiative, and get it into the constitution"

This is the same case in Texas.

codeodor··on Google Chrome for Mac
Funny that I'm getting news about it here. I signed up for updates about it a while back, and haven't seen anything.

I don't check the spam folder on my gmail account, but it'd be funny if that's where they're going.
