lsb··on Lipogram
A lipogram is not difficult to do; I'm anticipating thousands of HN folks to try a hand at a writing task that sustains its popularity, thousands of folks trying to fashion a long-form post worth a look.

What is mostly unknown is a lipogram that tops any list of books that attain financial grandstanding (A Void notwithstanding), which brings a quick sadness.

lsb··on Show HN: Human Lambdas – Create Human in the Loop queues and outsource them
Interesting launch!

0) Why is this better than MTurk's predefined workflows?

1) How much does it cost?? MTurk charges min(0.005, 10%) for each Human Intelligence Task.

2) How is quality checked???

3) People doing tasks generally report greater satisfaction and generally produce greater accuracy with a smaller topic shift (instead of doing NLP classification about everything at all times, first do topic A, then topic B). I bet you could train a simple classifier to group topics together

You're at 32-bit precision there.
lsb··on By 2012, scientists will have announced a cure for breast cancer (2006)
We don't have a cure for breast cancer, but we do have a cure for cervical cancer, especially now that we know that's caused by a virus (hpv).

And, we have generics to prevent HIV infection, and we have promising new mRNA therapies, that were in development (with woefully little funding!) at U Penn, when this bet was being placed!

Perhaps this is unwarranted optimism in the specific case, but as a broader expression of hope in future scientific progress, the long bet wins.

lsb··on Topfew and Amdahl
After you shard some of the computation out to different processors to filter before single core aggregation, then you can push down some pre aggregation to limit the communication between parallel threads, and it keeps going!

Super interesting to see parallelism for reading logs this way, like for when you have too many logs for one core and too few for Spark

lsb··on Solzhenitsyn’s Rosary (2016)
The data integrity operates on the level of story line and major themes. Formulae are at the word and phrase level. If the written is subordinate to the orally extemporaneous, like jazz, maybe you memorize a few star solos, but memorization isn't how you play a solo as a jazz musician. It's like asking "Did Hansel and Gretel see Rapunzel along the way?", and the answer depends on whether a book or a culture creates the stories their use.

If you have no writing, all of your community's texts are fan fiction with limit on headcanon. People brought tape recorders to Bosnia in the 1930s, to try to see how oral folk music worked, and to see how much it changed day to day and year to year, and they found that they couldn't glue the same story together from day to day.

lsb··on Solzhenitsyn’s Rosary (2016)
In ancient Greece papyrus was roughly worth its weight in silver. For a long time writing was so onerous that people just didn't do it.

The shared civilization behind ancient Greece and ancient Northern India and ancient Britain had a system of oral-formulaic poetry, wherein descriptions are full of stock phrases like "wine-dark sea" or "rosy-fingered Dawn", like in today's "My name is X and I'm here to say" in more recent oral poetic forms.

lsb··on Remembering Allan McDonald, who refused to approve the Challenger launch
1) Massive respect to Allan McDonald, for piping up in the hearing when he could have very easily kept quiet.

2) Massive respect to NPR, for continuing to publish news in HTML with minimal markup, quick loading for anyone to view.

You can get an SD card with 0.5TB capacity on it for USD$30, what storage needs do you foresee? Also these tend to be used where weight is an issue, so, why do you want to lug around a huge disk?

lsb··on Uber’s Real-Time Push Platform
At a certain mobile security shop ;) there was a push service rollout, back in 2013, and it was basically pings over the network, and mailboxes in Cassandra, no Redis layer atop. The volume was much smaller (~1hz), so it's interesting to see how the ecosystem has evolved, and how the volume requirements change the shape of the system

lsb··on USPS patent for reliable voting system secured with blockchain
Proposals for such inoperable [perpetual motion] machines have become so common that the United States Patent and Trademark Office (USPTO) has made an official policy of refusing to grant patents for perpetual motion machines without a working model. The USPTO Manual of Patent Examining Practice states:

With the exception of cases involving perpetual motion, a model is not ordinarily required by the Office to demonstrate the operability of a device. If operability of a device is questioned, the applicant must establish it to the satisfaction of the examiner, but he or she may choose his or her own way of so doing.

lsb··on Taking screenshots isn't allowed by the app after upgrading to Android 11
As long as the content is coming to your eyes, you can use another device to record it.

If you have a separate phone that you use as a second factor for your 2FA, you have a convenient way of photodocumenting any screen that you see.

People shakily recording their TV doesn't win any awards, but is evidence enough in a serious pinch.

lsb··on What to Say When You're Asked for Your Salary History
They are technically different questions, but think for a moment about what the speaker is trying to achieve.

This is not talking with a friend, making pleasantries. This is at work, getting paid, by a company, to learn how low an offer they can make for it to be accepted.

Pretending that the conversation is anything except that, is serving the interests of companies who try to do exactly that.

Telling someone that what they perceive is not what it is, that what others can perceive is not what it is, is like flickering the lights on and off, and saying nothing is wrong, and asking why someone is so upset.
