I suggested something similar but based on using Bluetooth and running an app locally. This would be more sensitive to proximity while potentially giving away slightly less data about exactly where you are, and easier to opt out of, either

One of my friends spends quite a lot of time organising pedestrian routes to optimally deliver (local government) material to every house in a zone. The goal is therefore to traverse every residential street twice, ignoring traffic flow rul

Databases such as postgresql will effectively issue a buffer of keys to each connection, meaning in some circumstances the sequences will not be monotonic with respect to time. Also that usually long running transactions will use the timest

We have rolled our own wrapper around selenium implementing page models, using pytest. It feels as though we are reinventing the wheel, though I'm not aware of an existing public package providing this. There are many caveats for the u

We also were frustrated at the verboseness and vagaries of the terraform syntax. We ended up preprocessing them using jinja2, injecting our variables via its context, and using its cleaner syntax for expressing conditions, loops, etc. Now w

The sole reason I rooted my pixel 2 was to install a simple app which disables charging when I reach 80%. I get all the wins of not killing the battery by constantly saturating it, together with being able to leave it plugged in whenever I

I threw together a few words here about how we are using Streams combined with Sorted Sets to "upgrade" legacy databases to streams of data. Not revolutionary, but it could be interesting to some people. I can write more, if there

I'm not sure I understand the wins of this over just using the standard multiprocessing module. You can trivially define a worker pool or arbitrary size and pipe a stream of values through your function using multiple cores, avoiding G

My naive perspective is not that software engineers should forsake iteration; rather that their tests / simulations have to be "out of this world". After all, the software is still written by taking real world constraints and

Looks interesting, though the installation documentation needs a bit of love. The PPA is quite out of date and the install from source instructions aren't super easy to follow.

What is the recommended way of UDP tunnelling wireguard? Is it necessary to run something like pwnat alongside it, or is there a better way? Using a TCP based VPN there are services such as ngrok for exposing only the VPN endpoint behind a

This is nothing to do with a protocol breach: it was an intentional disclosure by one of the ~100 members of the party's WhatsApp group.

I just tried the following, to German, and got the predictable result, which is completely wrong. Until the proper semantic parts of the text are identified, these sorts of mistakes prevent statistical methods from being trustworthy: Sailin

From the blog post, it sounds like the RDB format will break. Is there any means to upgrade from the current unstable RDB format to the v5 one? Obviously there are no consumer groups in unstable now, so in theory reading from a v4 RDB shoul

Why wouldn't a driverless car have a means of signalling nearby people? When it's not possible to directly indicate you are aware of a pedestrian by waving, a quick flash of the headlights is common.

When I selected the double spring and pulled back the outer mass, as I let go the distance between the two masses went negative. This caused a runaway effect, sending system energy towards infinity. Cute but the models are not very robust

I have a tiny PR for the python redis client. Makes it even easier to see the power of this pattern. I'm in the process of using streams to shift away from legacy tight coupling of databases to async operations. The real killer feature

I would think the imminent Redis streams data type would provide this better. It is battle-tested and allows great customisation to a range of use cases.

If A and B have already mutually validated each others' keys, and B and C have, then B can act as an intermediary to relay the key fingerprints.

Are there any recommendations for combining these sorts of sensors with long-range radios (e.g. HC12) and building a mesh network? Power consumption is less critical an issue as usually a small solar panel can provide topups. I am tempted t

You need to trust your mail relay to not go offline or you lose the ability to reset your password etc. Worse would be if someone used the relay to intercept a password reset and pwn you. Better to implement filters on Gmail or whatever, se

My approach: keep my "raw" requirements. \.txt files in a ".requirements" directory in the project root. The packages listed here mainly are bare, without a version qualifier. I run the script at https://gist

hey, why not allow people to supply a Kindle email address so you can push straight to them? they need to whitelist you as a sender of course..

That would just make it easier for a MITM (and maybe others) to spoof all your static content with legitimate signatures.

Long press on an article should bring up options such as 'mark read to here' and 'mark read to bottom' and probably some sort of starring feature, similar to RSS readers. I other to do a first pass to triage the entries
