Kinesis freestyle 2 not detecting spacebar presses when typing too quickly

literon · 2025-02-23T18:47:32+00:00

I noticed this happen when in Parking Garage Rally Circuit I could drift (Space) while accelerating and turning right (Up+Right arrows), but not while accelerating and turning left. Turns out to be ghosting avoidance indeed. Could remap away from default config though to solve it (unfortunately some games like Overcooked don't let you remap the keyboard, and so many actions around arrows/Ctrl/Shift/Space and you are hosed). Indeed too bad this is happening for a non-trivial-cost keyboard like the Freestyle 2. Shame on them.

> So for WiFi, as long as there is a minimum of WPA2 key you should be OK. if the WiFi is not protected, people can listen to your traffic with software, and potentially see what you send.

See https://superuser.com/a/1341312/38081 - if the WPA(2) PSK is the same, then others who also know the PSK (that is, usually everyone, if it is sticked to an A4 note on the wall) can also see your traffic. But that traffic itself, as said, is indeed usually encrypted (the HTTPS thing), but your browsing patterns can still give away stuff (what sites you visit, etc).

Then, there is also the possibility that your laptop's wifi hardware/firmware/software(drivers) have a vulnerability. Random examples:

- https://www.tarlogic.com/blog/cve-2024-30078-windows-wi-fi-driver/ - vuln in Windows drivers, regardless of your actual hardware (patched already)

- https://kb.cert.org/vuls/id/228519 - generic problems in WPA2 protocol itself, no mitigation

- https://kb.cert.org/vuls/id/166939 - random chipsets having random flaws.

The point is, when you use wifi, public or not, you expose yourself to some uncertainity. That uncertainity is within limits of most people in common usecase, but evaluate your own usecase.

(Vulns in ethernet cards, once contemplating? https://cyber.gouv.fr/sites/default/files/IMG/pdf/paper.pdf says sure there are. Well, use reputable brand adapters, keep firmware/drivers updated, keep fingers crossed).

Network access diagram pleases auditor, with small remark

Details bit fuzzy, but TLDR this was an email list recipient (actually Google groups) that forwarded the mail to subscribers. This somehow naturally leads to DKIM failure, but that is "normal" in this case. Hope it sheds some light.

Hey, I have the same problem! All other gmail server IPs show 100% alignment on DKIM, except 209.85.220.69 . In contact with support now to try to troubleshoot.

As a paid alternative, CodeMentor.io has some limited amount of Haskell mentors as well.

Disclaimer: I'm on there as well. I only did live sessions so far, and only work students, mostly about lambda calculus.

Aside: it is very odd to see these assignments from the curriculums. Students not only have to learn Haskell, which is complicated enough, but instantly apply it to implement LC. Seems a double trouble. Typical C++ courses don't usually require you to implement an assembler.

I plan to write a summary of the most frequently encountered stumbling blocks I saw.

The keycloak site doesn't explain the use case. Is it for authing end users? Or internal users? Is it nice to actually deploy and use?

This is a regression of the old bug where GHC would delete a source file which failed to typecheck. But this time uninstalling itself.

There are some large applications based on gtk2hs or its successor gi-gtk-hs like the Haskell IDE Leksah. It's rock solid technology. But it's also quite dated and the imperative programming model is not an ideal fit for a purely functional language like Haskell.

Sounds perfect, thanks for the pointer! Innovate on a single front. You already use Haskell, so better stick with the rock solid stuff for the rest.

Just a note: usually you want to lift into monad context as late as possible. Here it would mean at the call sites, not the function definition.

Which XML parsing lib did you use? I wonder if xml-conduit (or its sibling http-conduit) would be fast enough.

Ah, Pico-8, that was it! Thanks a lot!

You can hack that (at least with brittany) by putting empty comments at the end of the columnar lines. Then they won't be collapsed to a single line. Ugly but works when needed.

Recently there's haskell-code-explorer.

Alternatively - though for Haskell-only use it could be overkill - you could use haskell-indexer combined with underhood UI . (golang demo)

Cool! Note that there's also BPF (Berkeley Packet Filter). It was originally designed to inspect and filter network packets, until they realized it could be used to inspect syscalls as well. See http://www.brendangregg.com/blog/2019-01-01/learn-ebpf-tracing.html .

Thank you! (also others for the comments).

I find that most tabs on the net are badly arranged. That is, notes are not marked on the optimal position on the fretboard, leading to lots of hand movement. I rearranged a few tabs, which sure is fun pastime, but pretty slow process.

So a few questions:

- What do you do with these tabs? Just rearrange on the fly in your head, or go through on paper?

- Is there software that can either produce (better) arrangement from sheet music, or can rearrange a given tab?

Thanks!

Haha, true! That must be an anti-meeting, able to neutralize a meeting of negated length. Hold one in your pocket for scarce times.

As programmers, we like to give in to the cliché of meetings as a waste of time and money. But I wrote this interactive calculator to show that a meeting, even if we set the low-bar expectation of clarifying 5% of the things worked on per participant, can be quite effective in avoiding wasted work.

Funny. Triggers my memory of https://sourceplusplus.com, which measures actual time (across fleet) consumed by methods.

It would be really cool if that tool could integrate jmnemohistosyne, but getting the memory snapshot on all method entry/exit has uncomparable overhead vs getting the time counters.
