lorax··on Show HN: Perfect 2.0 - Send a postcard with ease
Before filling out the postcard I would want to know how much it costs to send it and what pictures I can put on the front. Neither of those seem possible
lorax··on Mozilla Location Service: Geolocation lookups from public cell tower, WiFi data
It is pretty cool that I could see a difference in coverage between when I read the article and when I got home from work. A bunch of people must have installed the app after reading about it here.
lorax··on My Friends and I Bought an Island
Yes you can, you still have to have a powerful enough military to defend your claim. In fact, given a large and powerful enough military you don't have to buy the land before claiming it.
lorax··on Welcome to the ‘Sharing Economy’
And yet, that regulation was probably created for a good reason, to protect consumers from car companies selling cars that they had no way of servicing effectively if something went wrong with the car or if there was a recall.

Maybe Tesla has found a way of profitably selling cars and servicing them without a dealer network and the law should be changed. Or, maybe Tesla just isn't big enough to have had that problem yet.

lorax··on Who Owns Your Pictures?
You should also support xmp. It is an XML format that gets embedded and isn't quite as much of a mess as exif. It also is a common metadata standard that applies to more than just image files.

lorax··on Google Bot now crawls arbitrary Javascript sites
It is likely that googlebot is running the chrome browser, so anything you can do in chrome, googlebot can do too.
lorax··on Good or bad weed-out process? https://github.com/m2mIO/hireme
It certainly will keep the recruiters away.
lorax··on A Better Strategy for Hangman
If you aren't taking into account the length of the word, then it looks like the optimal choice of 5 consonants and 1 vowel. Look at his section titled "First refinement" the most common letters were (in order) "ESIARNTOL" Eliminate all but the first vowel and you get ESRNTL, the same as WoF.
lorax··on A Better Strategy for Hangman
An even better strategy would be to weight your guesses towards the most information gain. If a letter appears often, but is in the same position most of the time, getting it won't help you as much as getting a letter that appears in fewer words but in more varied positions. Doing a quick check of 5 letter words in my /usr/share/dict/words file I find: S: 659,62,267,260,2282 E: 122,829,448,1254,679 A: 252,1201,678,410,307

That is, S, when it appears, is heavily skewed towards the last letter in the word, finding it won't help you figure out the word nearly as well as finding the more evenly distributed E or A.

lorax··on Ask HN: Should I ask for user demographics on the registration form of our app?
If you ask for demographics you will not only get increased abandonment, you will also get a lot of incorrect information, would it surprise you to know that I'm a 95 year old sumo wrestler? Your users don't care that you will get higher advertising rates due to "ad-target specific demographics". Don't ask for demographic information unless the user can see how it will benefit them directly. Facebook gets peoples correct birthdays (most of the time) because if you put in the right one, you get birthday wishes from your friends.
lorax··on Algorithmic Complexity Attacks and the Linux Networking Code
A bit old (2003) but nice to have another example of exploiting hash table weaknesses.
lorax··on Let's make TCP faster
Most of these changes seem focused on improving small, short-lived connections. IRC and SSH are mostly long-lived and I don't think it will have a noticeable impact on them. For large bulk data transfers (like sep or ftp) the Proportional Rate Reduction for TCP (PRR) should help.
lorax··on Building a Modern Web Stack for the Real-time Web
Why do you think multiplexing multiple independent streams at the application layer instead of the transport layer is a good thing? Now that people are using it they find they have to re-implement the other things the other things the transport layer does (like demuxing the stream and sending each part to the correct backend service)

Yes, replacing or modifying TCP would be a long, slow process, but so is re-implementing all its functionality at the application layer. Google introduced SPDY over two years ago (Nov 11, 2009), and as the article points out, there is still a whole lot of work that needs to be done before it lives up to its promise.

lorax··on Before shutdown, Megaupload ate up more corporate bandwidth than Dropbox
"BitTorrent is also quite popular in the workplace, and some people are even installing Tor clients on their work machines to conceal details of their Internet usage, the study found."

Some writers don't do their homework. Confusing bittorrent and Tor gives it away.

lorax··on Building a Modern Web Stack for the Real-time Web
On one hand, you have tcp, which already allows you to multiplex multiple streams, every bit of software understands it, and your back office web application servers fully support it. Yes, it has limitations (slow start applying to individual streams instead of all the streams between two computers seems to be the primary one), but instead of trying to fix it (which admittedly would take a lot of work and would be a slow process), you take a single tcp stream and implement multiplexing all over again, now you have to work support into all your applications from top to bottom. Not surprisingly, this also takes a lot of work and is slow process.
lorax··on The lost Van Jacobson paper that could save the Internet
VPN's don't use TCP because having a reliable protocol with retransmission inside another reliable protocol with retransmission can cause lots of extra traffic when a packet is dropped and the data gets retransmitted multiple times, once from each of the protocols.
lorax··on Groupon has no viable business model
Agreed to a certain extent. The real question you have to ask is "If they hit their scaling targets, would it be successful", for Amazon, the answer was yes (thought there were significant doubts whether or not they could hit their targets). For Groupon, people question if they could be successful even if they hit their scaling targets.

BTW, people also questioned AOL for shipping all those CD's and counting it as an investment instead of a marketing expense.

lorax··on All NeXT Inc.'s Plant Lacks Is Orders (1990)
I wonder how that plant compares to electronics plants Tory. Would it still seem up to date or would it be hopelessly outdated.
lorax··on Ask HN: Digitizing Books That Aren't Available Electronically
If you own the books and you aren't planning on sharing them then you are just format-shifting which is perfectly ok.
lorax··on More letters to RIM; employees rally alongside anonymous exec
I bet there are a lot of people out there that see parallels between RIM and the companies they work for. Sadly, I don't think RIM is in any way unique and is more the norm than the exception.
lorax··on Lets just drop the 5 from Perl 5
This seems like a change similar to the perl 5.000000000008 to 5.8 change (yes, I know it had fewer 0's in it but there were a lot).
lorax··on New York Post blocks iPad. Not a new Strategy. Here is how to Avoid the Block
Here's how to avoid the block: Read a different newspaper.

It's not like New York Post has a monopoly on news, if they don't want your pageviews, give them to someone else, don't bother trying to trick them into showing you the article anyway.

lorax··on The Quora post that killed Bitcoins. Please discuss if his arguments are valid.
Talk about an overly dramatic headline, the "post that killed Bitcoins"? but the submitter isn't even sure if the arguments are valid? (And has hacker news turned into bitcoin news? it seems like there are several bitcoin links a day)
lorax··on Twitter sued for ‘breaking’ UK super injunction. Oh yes.
If you are in the UK, how do you know which people you aren't allowed to publish stories about? How do you know if a super injunction is in force? Are they published somewhere?
lorax··on Netflix Makes Amends For Outage
Wow, 3%. At $7.99 a month, your credit will be 24 cents.
lorax··on IBM's Watson starts on Jeopardy Tonight
I hope someone writes down all the answers (questions?) and feeds them into google so we can have a Google-Watson showdown. (Oh, we need a third contestant, how about bing too).
lorax··on The Geocities Torrent (~1TB of awesomeness)
Hard to say if it was the first or not. It may have been "Here's my list of interesting web pages (most of them were probably links to other peoples lists of interesting pages, very recursive.)" I don't think the word meme existed then either.
lorax··on A touchy legal problem with LinkedIn and restrictive employment covenants
From the article: "many, though admittedly not all, courts have held that contacting former clients regarding a change in employment constitutes a solicitation. See e.g., Merrill Lynch v. Schultz, 2001 WL 1681973, *3 (D.D.C. 2001) (noting that “such initiated, targeted contact is tantamount to solicitation because there is no reason to believe that a customer on the receiving end of such a [communication] does not assume that the [employee] wishes for him to transfer his account.”)."

This reasoning doesn't necessarily hold for linked in. If a person has lots of contacts on linked-in, some of which are customers and some of which aren't, changing your employment status isn't targeted, wasn't specifically initiated, and can't be assumed to be a solicitation.

lorax··on Work Less, Get More Done: Analytics For Maximizing Productivity
So, two people of equal intelligence, wealth, ability to work long hours, etc. are in a field... who is more successful? The one who spends a lot of time doing repetitive tasks or the one who automates those.

As I am pointing out now, the stories of great things being done by people with insights about automation are absolutely overwhelming. Eli Whitney, Cyrus McCormick, Henry Ford, Jeff Bezos ad nauseaum.

That's anecdotal, but then you dismiss the science behind using automation and productivity enhancement to become good at things elsewhere in this forum.

Sure, if everything except hours worked are equal, working longer hours helps, but if everything except intelligence is equal, the more intelligent will win, and if everything except wealth is equal, the wealthier will win. In real life, all other things are never equal and assuming they are in order to prove your point is a strawman argument.
