While Pi is not proven to be a disjunctive number, nor the stronger condition of being normal, it is generally believed to be normal. That being said we don't have a proof of Pi being normal, nor disjunctive. I am not familiar with h

OEIS is amazing to say the least. It is such an interest collection of sequences as well as a great collection of editors that are willing to keep it all in order! Certainly worth a mention and a contribution.

Ha! Yea, that is true.. now if we only had a printout of it!

Yep! I suspect there are lots of different ways to optimize this search, especially with some heuristic approaches. One of the great things about HN - There is always someone with a better way!

It is, as far as being a math problem, somewhat boring. The numbers themselves are equivalent to a random number. There is certainly no significance to the numbers themselves, especially as this is all in the decimal representation, which

Oh that is interesting!.. and indeed I did consider doing a 'hash compression' where I would generate offsets to numbers that might be similar, then do direct comparison on those ones that are similar. I'll take a crack at

Yep - This really is just a random number problem.. it is only interesting in the sense that Pi is something that has been captivating in public math perception. Any random number would have the same characteristics.. It is however someth

Indeed no worries about pointing that out! - there are lots of things that could optimize the RAM requirements, and especially reduce the runtime. Since the overall runtime is pretty quick to getting a single answer (3 hours) vs spending m

I worked at Intel during the AG days, and by far the most noticeable change is the larger number of non-profitable activities Intel is engaged in. 130,000 people is just too many for the products they sell and the revenue they generate. If

That is awesome. I live in the PNW (Oregon,45°N) and the summers here are fantastic for solar power. I have a 20.2kW system on my roof and crank out 100-120 kWh a day in the summer months. I can store 42kWh, and push the rest back to the

Ah yea, no worries. It is always good to consider ways to optimize, either for TB or PB!

When I first read the title I had in my head that it said multi-petabyte. When I think Multi-terabyte, I think 'yea, that is mostly in RAM'. 4TBs of RAM is sort of the new lower norm in DB machines, and GCP and AWS have high RA

I am in a similar boat - When I was an engineer at Intel during the Windows NT days, I used SoftICE every day... but over time I have evolved into using less debugger tools and more emulation/simulation tools to find problems.. and eve

Interesting... My initial reaction about the startup looking for a CTO was the same as yours. I was a founder and CTO, so it seems odd that you would not already have that in the mix... however I can see how there could be an idea, a marke

"> I have known zero founders who have turned down an option to take money off the table (and zero A raises that offered that to employees)." Nice to meet you. Now you know one. :)

I was thinking the same thing. A camera capture would be fast and accurate if you were going to ocr.

Yea, a lot of them are pretty high flow due to the density of heat generated. Most are consuming 100-200watts, and that has to all come out as heat!

Yea, it is impressive when they first turn on. You really start to think there is an aircraft overhead!

Indeed - They are loud. ;) You can slow the fan speed down some and that makes a difference, but they still produce a lot of fan noise: If you listen in this video of my homelab: https://www.youtube.com/watch?v=-b3t37SIyB

Those Mellanox cards are great and surprisingly inexpensive. I just put 4 of the dual QSFP+ cards in servers in my homelab and now have 80gb/s from each server. The Mellanox and Arista QSFP+ switches are also super cheap, and you can

I really enjoy reading about what people do in their homelab. It has turned into platforms that encourages actual 'doing' in contrast to just 'thinking about it'. When I am interviewing to hire a DevOps or System Engi

From a boolean logic point of view - AND is irreversible, since (1 .AND. 0) is 0, as is (0 .AND. 0.) Going from the result (0), you can't reverse and get the starting inputs. NOT however is reversible, since 1 .NOT. -> 0, and you c

Sweet! Yea, I have several panels that have 2 of them for that reason. I have debated making a larger one since the code is open source. It would be great to have one that has more ports, and perhaps the ports combined into less cables.

That is cool! Indeed there is a good cross section of home automation , software development, power monitoring, and hacker news. I just did a new video on building a 68030 computer that I suspect will have a much smaller audience!

I used IoTaWatt devices, which can be installed in panels. It is a great solution for by circuit monitoring, and has direct influxdb integration so you can use Grafana. Per plug monitoring is cool however for getting specific devices on a
