I haven't used this yet, but there's also https://github.com/robotocore/robotocore. It came up on HN a few days ago: https://news.ycombinator.com/item?id=47420619.

Show HN: Vischunk, explore 2D array chunking and linearization

bytK7 — Wed, 03 Sep 2025 20:28:45 +0000

Hello all! I work with geospatial data infrastructure at scale, so I end up thinking a lot about how n-dimensional datasets are stored. I've been spending a lot of time writing about raster array storage and data formats with a colleague, and one hard concept to talk about and for people to understand is data linearization. It's especially hard to then communicate how different chunking and linearization strategies affect the efficiency of read access for different access patterns.

On a whim, as a backend engineer, I asked claude if a static webpage could be used to visualize this in an interactive manner, and what it spit out was pretty amazing. A few days and much iteration later, and I think what has resulted is a rather useful tool for understanding chunking, linearization, and the impacts of each on data access. So I wanted to post it, let people play with it, and see if others find it interesting and/or useful too!

Does it mean you’re actually right when you get it to proclaim “Holy shit, you’re absolutely right!”?

I did get it to say that once, after I prompted it to be mean and argumentative and make me defend my idea. I did defend my idea, but I’m still not sure if I was right or not.

As a fellow resident of Bend I felt the same way when I saw this.

Reminds me of Mel Chin’s art piece Revival Field[0], an attempt to remediate a hazardous waste area in Minnesota with plants. Apparently it is still going after more than 30 years.

Indeed, bash already has socket access via /dev/tcp/HOST/PORT and /dev/udp/HOST/PORT, which allow opening a socket and reading from/writing to it as if it were an ordinary file.

bytK7 — Sat, 19 Feb 2022 23:08:40 +0000

I think there’s a misunderstanding of the data _here_. The underlying data are indeed a DEM, distributed as a single band geotiff file. There’s no R, G, or B, just elevation. The linked tutorial is simply how to take those data and convert them to a format that can be visualized on screen _using_ R, G, and B values derived from the formula you posted in a child comment.

New comment by bytK7 in "Cog resurgence"

bytK7 — Sat, 15 Jan 2022 17:44:49 +0000

You’re right, I realize now that cog doesn’t process an input template but the actual output file, modifying it in place. Perhaps that why it took so long to gain popularity: that fact seems somewhat non-obvious from the documentation. Even the examples on a cursory glance are not obviously not templates. At least to me.

Re-reading the docs I realize that sure enough, they say very clearly what it does. But I think it just doesn’t click immediately.

Now that get it, I have a few problems coming to mind that I can solve with cog that I didn’t have a great solution to before. So I’m jumping on the bandwagon.

Looking at this reminds me strongly of texthon, but with a less attractive syntax. A quick skim through the source appears to show a similar use of eval.

Too bad texthon is essentially unknown and unmaintained, as far as I know. I worked on a project with it for several years and it always worked really well and was much more pleasant to use than something like jinja. Maybe I need to make a modern fork…

Anyway, anyone interested in cog should check it out as well.

I don't know enough about this so maybe dumb question, but couldn't you use DSP to correct phase between microphones if you knew their relative differences?

New comment by bytK7 in "Inferring and hijacking VPN-tunneled TCP connections"

bytK7 — Thu, 05 Dec 2019 16:24:27 +0000

I was thinking the same thing as I read the on the description. I see no reason that a separate VPN namespace would be vulnerable to this attack. The compromised device would be able to spoof packets with whatever IPs it wanted, but they would never be received in a context where the tunnel interface would be directly accessible and therefore the device would never see a response from that address, even if correctly guessed and probed.

I am currently working on a masters in geography with an emphasis in GIS/remote sensing, but through my work I have come to learn I have a love for programming and development. I want to pursue a second masters in computer science, but I currently cannot afford to continue to be a student. My wife is also a student, so two people with no income paying exorbitant tuition is not possible to sustain. That why I am posting here.

My experience is limited and I only really know python (I am learning C++ right now), but I am driven and willing to work hard to learn any language, platform--anything and everything necessary to be successful. If someone here would be willing to offer me gainful employment and direction, I would prove myself to be valuable.

All I ask is for a chance, at least just a meeting, so you can get to know me and see that I am serious about doing whatever it takes to succeed in this field. If you think you might have an opportunity for me, please contact me at the email above.
