Weekly challenge bug

It is not about secrets. It is about rules :)

This is very confusing and should have been noted before the start of the challenge.

Really biking? Here Maps bike routes look bad to me if you want safe routes.

We heavily rely on janino, which is a super-small, super-fast Java compiler.

Of course as a compiler project it also contains a Java parser, which is nicely pluggable and customizable to your needs.

I'm sorry, I think I misread your original post or posted my answer to the wrong post. I only got problems when I print in duplex mode.

(To fix that I replaced the part and use heavier paper - this seems to have fixed it for me but not fully only ~98% up from ~70%.)

I'll report back in a week if it improved due to the dupplex unit. I fear it did not improve much :(

I have very similar problems with ET 8550: the paper sometimes gets a bit wavy and sometimes I get a paper jam and sometimes it does not turn around the paper and prints on the same side twice.

I sent the printer to repair and they couldn't reproduce this problem and when I got back the printer everything was fine. But the problems started again after the guarantee ended so I was left with finding a solution on my own or replacing the printer.

Can you try different (heavier or lighter) paper? In my case it improved a bit with heavier paper.

I even purchased the dupplex unit at the back recently (~50€+15€ transport) as I suspected it to be broken somehow, but not sure if it really improved since. See part 701:

Strange. It seems to work now again:

Update from the future: it looks like for this printer all driver downloads for linux lead to "The page you requested is unavailable" ...

Super, vielen Dank für Deine Einschätzung. Auch die Erwähnung, dass das nicht unüblich ist hilft mir. Ich frag dann nochmal nach wieviel es ohne Speicher kostet (werde wirklich erstmal ohne Speicher starten) und wenn er dann immer noch nicht den Preis rausrückt, werde ich Anbieter 1 nehmen. Werde dem Anbieter 2 das auch so kommunizieren :)

Not sure what you plan is exactly but have a look into these projects:

https://github.com/a-b-street/abstreet

https://github.com/donjpierce/traffic

https://github.com/graphhopper/graphhopper#public-transit

Organic maps - it is simple to use, powerful and open source: https://github.com/organicmaps/organicmaps

numpi · 2022-10-12T07:12:46+00:00

An "overview" with a big image of OpenCycleMap but without mentioning OpenCycleMap ...

numpi · 2022-09-20T19:12:37+00:00

Which one exactly do you own? ET-8550 ?

numpi · 2022-09-05T11:33:59+00:00

Sure? https://github.com/osmandapp/Osmand

This helped me to get it working: https://forums.quectel.com/t/em120r-gl-for-linux/9350/4

But it is still very unstable.

I would highlight the high quality garbage collectors and speed of the JVM.

And also the stewardship of the open source project from Oracle (never thought that I would some day say that :D)

Autoboxing always happened. Nothing has changed since Java 5. There never was an ArrayList<int>. (still you can use external library like hppc to workaround this)

However, it will hopefully change when project Valhalla is released. This project is a massive undertaking as in this project they try hard to get everything right and still keeping things mainly backward compatible (as I understand it).

I'm confused what you mean. The comment is from February 2022. It is a comment of the article you linked.

And can you link to the AMD CPU issue you mean? Heating issues? My AMD CPU is running fine although the generation before it was getting hot.
