At one point, maybe 10 or 12 years ago, there was lots of buzz about electrowetting displays that were meant to able to display video. I think that Phillips were working on it. Then I never heard of them again. On the other hand, it's

There has been a lot of work in this area. There is no best algorithm, it depends upon the problem that you are trying to solve. However, I think that r-trees have advantages over k-d trees for this 2d case. Alternatively, there are Quadtre

In general, developing gui is still too hard with too many trade-offs. Qt is so very large and requires C++ knowledge; or you can develop in python but python applications are hard to distribute. For other languages, the library bindings ar

One difference between the UK and Europe is that the clubs get started even later in Europe like 00:00 - 06:00. They seem to get later as you go further south so maybe it's something to do with waiting for the heat of the day to fade (

This is so cool and I would have loved to have had this while I was still an academic for diagrams and interactively playing around with setups. For real design, of course the maths gets harder and the software get more expensive. The close

This is an interesting article which feels plausible and close to my own experience - not that I consider myself to be one of these ultra people (nothing could be further from the truth). The internet contains a wealth of knowledge. However

Am I right that tabulator-qt and tabulator-qtpy are still under development since they don't seem to load csv files yet? But they certainly look like the type of specialised viewer that I have been looking for.

I have also wondered whether a viewer like this would be useful for inspecting apache arrow [1] datasets since that is a format for tabular data and seems to be rising in popularity. [1] https://arrow.apache.org/

Of course, excel can be used to read csv files and do basic analysis but in my experience it takes too many steps to import a csv file and it doesn't handle datetimes at all well ie. iso8061 format - 2020-12-29 13:29:10. You can also s

I will try all of them. Previously, I've tried Tad [1] which is good but I'd like something lighter and faster (ie. not electron based) and also visidata [2] which is terminal based but sometimes I just want to see my data in a gu

I've been intending to create a lightweight csv viewer for some time now and I was even learning Qt for that purpose, so I will definitely be checking this out. On windows, I use Nirsoft's csvfileview to rapidly review my files bu

In my experience, all of the complexity comes from feature requests following the initial development of some code. I develop code for our internal automated data analysis systems. My boss doesn't care how it works, it just has to do e

I think that a version of this idea underpins the operation of the matrix messaging protocol. Rather than just sending the latest messages, the conversation is synced between clients to ensure that everyone sees the same history. [1] https

We've all gotten used to the idea that Electric and Magnetic fields are real but then we learn about the Aharonov-Bohm effect and suddenly, maybe it's the electric potential and magnetic vector potential are what is 'real&#x2

As a Brit watching from France, I have been a bit perplexed how the antisemitism issues have kept being brought up in the news. It reminds me a lot of Hilary's email server issues. Yes, there is a problem that needs addressing but it f

As a physicist rather than an EE (although I'm neither now), antennna always led to confusion. In particular antenna effective area and reciprocity. Trying to imagine a 1d dipole antenna funneling some 2D part of the incoming wavefront

My least favorite type of latency is when you start typing and the application takes at least 1 - 2 seconds to catch up with you. This still happen to me often enough to be a normal occurrence on both my desktop computer and phone.

I also really liked the article and found it thought provoking. This is all way above my pay grade but I like to think that there is a more optimal cpu design and language pairing that we will eventually reach and it's fun to imagine w

I use the nirSoft CSVFileView utility all of the time. The near instantaneous load time is how computing should be.

Actually, please don't get rid of the GC. The GC makes programming easier and there is rust now if a programmer believes that they can not possibly tolerate one. Complaining about the GC is like complaining about python's white sp
