I'd add an animation of some sort, what do you think +Jakub Steiner?

The ODRS exports some stats, and the below is the total number of people contributing a review with a set number of stars. Is this expected? I know the Ubuntu-specific reviews plugin does a Wilson's confidence interval adjustment for each app and I wondered if those with better statistics knowledge than me would know if I should do the same. If it helps, the average number of reviews for each app is 2.5 in all languages, although that's significantly higher for popular apps. I'm not sure if the low average makes Wilson pointless or even more required. Thanks!

Out of interest, what are people using gnome-packagekit for? It seems to be a super-popular thing to install according to the review server.

Reviewing the change logs of the things I am going to update without having to do fourteen (ok I exaggerate -- two or three) mouse clicks per package. And as mentioned previously, not being forced into a reboot to do updates. Reboots are very disruptive.

GNOME Software in #Fedora 24 allows people to write an end-user review of specific apps so other users can better choose the correct application to install. So far we've had loads of great reviews from hundreds of people, but the majority are just in English, en_GB, en_US and en_IN etc. A lot of users in other locales are writing reviews in English too.

For Fedora 25 we're planning to show the "star rating" of each application more prominently in the search results, and this requires good high quality data from end users. This star rating is made up from end-users reviews, and although we've got over 400 reviews already since the release of F24 a lot of these are for popular applications like the GIMP and a huge number of applications are thus missing ratings data. This is going to make the UI in GNOME 3.22 look non-awesome, so I'm asking for your help.

If you've got a spare minute or two, I'd really appreciate it if you could write as many reviews as you can in your native language for apps you either love or hate, perhaps concentrating first on the applications we install by default, or the applications we've chosen to be "featured" in the various categories. Even having a couple of reviews in each language for just the core apps would be awesome and would look great in the F25 release notes. Thanks!

+Marek Suchánek I fixed up your reviews on the web console.

Bi-monthly reminder about gnome-software -mode=moderate - there have been a HUGE number of reviews that have been submitted in the last month, and a lot of them only have my karma points. I also don't speak anything other than English, so a large number of es, fr, pl and it reviews have no karma at all :(

Or just read the $LANG variable.

Calling all C gurus. I've got a Wconversion issue that's driving me crazy. Accessing u8 array members seem to be promoted to int, giving warning: conversion to uint8_t from int may alter its value -- test code here: https://paste.fedoraproject.org/396434/96324861/ -- any ideas?
Fedora Sticky Notes is a feature-rich, yet lightweight paste utility

+Richard Hughes: the problem is the +=. That's equivalent to:
checksum = (int)checksum + (int)buffer[i]

Both operands to + will be promoted to int before the addition. That means the result will be between 0 and 510, so there are 255 possible values that cannot be represented in uint8_t. The warning is, strictly speaking, correct.

Usually, you can silence this warning by explicitly casting back. I wouldn't expect that using unsigned would silence it because the conversion from unsigned or signed to uint8_t proceeds the same way and is well-defined. (see C11 6.3.1.3 paragraph 2)

I redesigned +Ania Hughes HypnoBirthing website last week using one of the free templates from HTML5 UP -- I was really impressed with the code quality and will definitely recommend them for other projects. It looks great on mobile, which was one of the main downsides of the old site. Anyway, if anyone wants to critique my foray into webdesign the website is http://www.hughes-hypnobirthing.co.uk -- thanks!

Thanks! That is great sample code that shows how to use HTML5. That is easy enough to understand and do in a standard text editor.

Nobody is going to start complaining if I start using c99 in my projects, right?

It seems Fedora users are clearly the nicest Linux users submitting by far the most reviews. Perhaps somebody could send some emails to +Arch Linux, +openSUSE or +Debian mailing lists asking them to submit reviews of apps they love or hate. This could really be a great community outreach project for someone. To submit a review you just need gnome-software 3.20 or newer.

One more reason for arch is that most of the users are using command line pacman for installing and upgrading things rather than using GUI tools. I have been using arch for more than 2 years and the only point when I installed a GUI tool was when GNOME softwares were released. But later had to uninstall because of pacman major version change and dependency conflicts.

Is there a curated list somewhere that has a mapping of applications that go together well? For instance, Inkscape users probably also use GIMP too. There must have been some research done here in the past. Thanks!

You could try to connect programs via the supported file formats. Then you could try to find a heuristic to find the important connections. I would say, the more unique a connection is the more important it is.
e.g. MuseScore has a Lilipond export and Scribus has an Lilipond import. There are very few other programs with this connection, so this is an important connection. But a lot of programs support JPEG, so this programs don't need each other that much.
Perhaps this is stupid and it is the other way around. Perhaps it would help to create first at all a map/graph with all the connections.

I know everyone says don't write your own crypto code but with gnupg being so broken by design and the python bindings being so bad I don't blame people. Is there anything else other than GPG that can create and verify a public/private detached signature? Thanks.

I've seen libsodium highly recommended, particularly if you don't need to choose a particular algorithm for interoperability.

https://download.libsodium.org/libsodium/content/public-key_cryptography/public-key_signatures.html would be the public key signature API; you'd want the detached-signature code.
