lorax | 5 years ago | on: Proposal for an Internet Service: The Eternal Home Page (1996)

There are a few services like this today, some are fairly simple like memorial web pages or find-a-grave where you can add photos about the people named on the tombstones.

Expanding beyond that (and I think more useful) are eternal digital archives such as https://www.permanent.org/ which is a non-profit that charges you per gigabyte for perpetual storage. They store copies of your data with multiple providers (AWS and Backblaze right now) and promise to transcode formats as technologies change. you can make the archives public (letting you have the "eternal home page") or private so only certain people can view or update it. The money you pay goes into an endowment and the earnings from the endowment pay the storage costs.

I'm not sure that you should separate the "avoid waste" and "conserve energy", they seem intertwined to me. Recycling in the supermarket is part of their plan, but I don't know how much it matters (there are UPS trucks going through my neighborhood every day, the amount of extra energy required to stop at my house versus me driving to the supermarket seems like a wash).

My packaging consumption consists of a lot more than what I stated, I based my comments on the partners they listed and the examples they gave (on the terracycle website), they are going to have to move in to products that get used up every week or two, not ones that get used up a few times a year to actually have an impact.

Side note: the parent company, Terracycle seems like it is more about giving you the feeling of saving the environment instead of actually having a positive impact. Current promotion: recycle little-bites (a brand of muffins) packages by packaging them up and mailing them in, the cost (resources and energy) of doing that is far above any value the get from recycling a few ounces of packaging.

I'd like to know what the breakeven point is. How many times does the package have to be used before it becomes less resource intensive than single-use packaging, and how long will it take. I use honey (an example on the terracycle website) but I probably go through a bottle a year. If the breakeven is 10 uses, that would be 10 years worth of honey consumption. Even for shampoo, toothpaste, and laundry detergent I don't go through very many containers a year (but I buy big containers).

It seems like it will take years of re-use to make it less resource intensive, what's the chance a bottle will get lost, broken, or forgotten about during that time (or loop will go out of business).

> 48% of wager earners had net compensation less than or equal to the median wage

I'm surprised. I expected that 50% of wage earners would make less or equal to the median wage. If for no other reason than the definition of median.

lorax | 7 years ago | on: If You’re Over 50, Chances Are the Decision to Leave a Job Won’t Be Yours

This seems like they developed their conclusion then went searching for data to back it up. For example they only "considered only separations that result in at least six months of unemployment or at least a 50 percent drop in earnings from pre-separation levels." So anyone who found a new job before resigning their position isn't counted, anyone who switched jobs to one with more flexible hours but took less than a 50% pay cut isn't counted. They also didn't compare this number for people both over and under 50 to see if age had any relevance at all.

That is a pretty poor response, the IOTA team doesn't seem to know how cryptoanalysis works. Theoretical attacks usually are found first, then specialized attacks like the chosen message one shown here, then more general ones. Cryptoanalysis takes time, and it is best to fix your system when you still have time and not wait until a full, generic, attack is known.

The first rule of hash functions is "Don't write your own hash function" writing cryptographically secure hash functions is hard, and even expert researchers get it wrong as often as they get it right. Better to use one that has been analysed already than coming up with your own.

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.

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.

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 | 14 years ago | 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.

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.
