There are multiple sign-in options (one of which was selected by your employer) listed at https://docs.microsoft.com/en-us/azure/active-directory/hybrid/plan-connect-user-signin, but I think IMAP should work regardless. My workplace uses federated authentication, and davmail works fine for me. Have you tried and failed to authenticate using your email address and password? -- regards, kushal

You can -almost- always go monkey and do that one way or another, but I would like for Debian to make more official an offline mode for using apt probably based on java, so that any machine could be used to download packages to be then installed off-line for those of us who don't/can't see the Internet as a trusted environment. I haven't seen anyone mention apt-offline in this thread, so I will mention it now: apt-offline is an Offline APT Package Manager. . apt-offline can fully update and upgrade an APT based distribution without connecting to the network, all of it transparent to APT. . apt-offline can be used to generate a signature on a machine (with no network). This signature contains all download information required for the APT database system. This signature file can be used on another machine connected to the internet (which need not be a Debian box and can even be running windows) to download the updates. The downloaded data will contain all updates in a format understood by APT and this data can be used by apt-offline to update the non-networked machine. . apt-offline can also fetch bug reports and make them available offline. Homepage: https://github.com/rickysarraf/apt-offline I have no experience using it. Looks to me like for buster you need to get it from backports. -- Ce qui est important est rarement urgent et ce qui est urgent est rarement important -- Dwight David Eisenhower

how to use fetchmail with MS Office 365 / davmail?
Dear debian users, the company which employs me uses MS 365 (former Office 365) in a federated setup where users are taken from MS to the companys login server for authentication. Which means that I have to authenticate via a web form with the company's login server. MS does not know the passwords instead hashes are exchanged between the servers. Some clients (Outlook) are able to cache successful authentication for days but also need to relay authentication to the company's server. I would like to use IMAP to access email in order to circumvent Outlook, but AFAIK there is no way for fetchmail or other command line tools to authenticate via web page and use the IMAP Server then (Thunderbird is able to do this but I don't want to use Thunderbird). I hoped davmail would be able to do that but I have no clue how to tell davmail to authenticate in this way. AFAIK the only way is to provide a password which does not apply here. Any ideas, help?

That's fine, of course, but I'm just pointing out that your logic is a bit circular: you dismiss my anecdote in support of Google's superiority with the assumption that there exist counter-anecdotes as well, but your only basis for this assumption seems to be the assumption that Google isn't objectively superior ;) Of course, anecdotes are not data. And just to be clear, I really like DDG, certainly for its attitude and track record of taking privacy seriously, as well as for doing remarkably well as a competitor to Google with what I assume is a tiny fraction of its resources.

Hm. Good point. Of course, Google has a lot more resources than DDG. My hypothesis is that the advantage from that is rather marginal and that they get most of their advantage from search context. Of course, I may be wrong (as nearly always ;-) Could you give an example where DDG fails and Google succeeds? Here's a sort of example I just ran into. When trying to find information about Thetis hardware security keys, DDG simply couldn't find the company's website: searching DDG for "thetis key" turns up (in the first page of hits) a bunch of Amazon listings, and a bunch of reviews of, and articles about, security keys that mention Thetis. Searching for the same thing on Google, OTOH, returns the company's website (https://thetis.io) as the first hit (along with a convenient list of pages on the site). At least, this is what I get here. Who knows what you'll see ... Celejar I think Google tailors results according to what they know about you. Even if you reset the router to a new IP and clear all the cookies they still seem to know. I've wondered if the browser has an identifying number. mick -- Key ID4BFEBB31

These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from multiple partners, though most commonly from Bing (and none from Google). https://help.duckduckgo.com/duckduckgo-help-pages/results/sources/ > between Bing and Google.

Still it might tell us something by "backscatter" :) For example, I forced now DDG's hand by doing some "foo site:blah.blah". Tomorrow I'll check again and see whether that site is in the index. > This is simply because the subset of the internet that is indexed by the > two search engines is not simply in a subset relation.

FWIW, I'm pretty sure that such anectodal evidence is of no importance because you can also come up with examples where the situation is reversed. This is simply because the subset of the internet that is indexed by the two search engines is not simply in a subset relation. So the question is not whether such things happen, but how often they happen for your use-case one way compared to how it happens for your use-case the other way. And of course this question is only relevant as one of the properties distinguishing the two search engines. Obviously, the purpose of DDG is not to give better search results. BTW, as far as I know, DDB doesn't do its own indexing but it relies internally on Bing, so in the above is explained by the difference between Bing and Google. Technically they could probably just as well rely on Google (or on both). Stefan

I don't know about the rest, but Kodi usually requires extensions installed in order access external resources. Depending on where you are, cross-border `intellectual property' stipulations sometimes get in the way. Other than that, you shouldn't have any problems. Cheers!

Best desktop environment for multitouch touchscreen?
Hi all, I am trying to use a multi-touch monitor (Dell P2418HT) with Debian as a front-end for a media center setup. Ideally this system would work without having a mouse attached, and allow touching icons on some kind of Desktop or main screen to open specific webpages in Firefox and/or start programs. Having tried both KDE and Gnome I cannot really seem to get things to work the way I would like. KDE/Wayland: Works reasonably well, but the icons on the desktop do not respond to touch in any way, and the Start menu needs to be used. Gnome/Wayland: No longer has the concept of a Desktop, but even with the Desktop extension program shortcuts show up as files to be opened with a text-editor instead of "click and something happens". I've also briefly tried to use Kodi, but that does not seem to support launching external programs and/or webpages easily. Stuff like multi-touch in applications, pinch-to-zoom and 2 finger scroll are not working either. What is the best desktop environment or other application to try for this? Thanks, Kasper PS: Please put me on CC on replies, I'm not subscribed to the list.

Ecasound can correctly identify and open the audiofile in both of your tests above, with and without libsndfile. You can see it identifies the sample rate and channel count correctly both times. The problem is with the ALSA output. Something is wrong with the soundcard device, its driver or its alsa interface via alsahw,2,0. You could try listing the sound devices. aplay -L Choose one you want and use -o alsa,DEVICENAME You can also cat /proc/asound/cards. Oh, and make sure you don't have pulseaudio running. cheers > Please help if you can. > Thanks > > Rodolfo > -- Joel Roth --- End Message ---

[...] http://nosignal.fi/ecasound/Documentation/examples.html#multichannel I do not use ecasound but it seems to me that this indicates that by default ecasound is in a one channel (mono, channel #1) mode and that channels have to be specified with -a, perhaps like this: $ ecasound -a:1,2,3 -i:sndfile,3canali.wav -o alsahw,2,0 or perhaps $ ecasound -a:all -i:sndfile,3canali.wav -o alsahw,2,0

problème avec evolution et gnome-keyring-daemon
Bonjour à tou·te·s, Habituellement mon client mail ouvre un prompt graphique pour gnome-keyring-daemon dans lequel je tape mon mot de passe. Et là le prompt ne s’affiche pas quand je lance mon client mail (evolution), je n’ai rien changé à ma config. Comment lancer gnome-keyring-daemon pour qu’il me propose le prompt graphique ? gnome-keyring-daemon –unlock Ne propose pas de prompt… Dans un deuxième temps, comment lancer un trousseau de clés équivalant (capable de fournir les mdp à évolution) en mode terminal (J’ai configuré multi-user.target, donc je ne me logue pas en mode graphique) et utiliser le mdp de mon login pour ne le taper qu’une fois ?

Bonjour, Ce n'est pas la même gamme de produit et j'ai toujours eu beaucoup plus de problèmes de bios incontournables avec les non Thinkpad qu'avec les Thinkpad. C'est juste une constatation, je n'ai jamais investigué plus loin. L'impression que ça me donne, vu de mon bureau, c'est que la gamme Thinkpad surfe encore sur la qualité IBM et qu'ils essaient tant bien que mal de s'y tenir alors que les autres sont à peine mieux que du bas de gamme lorsqu'on y regarde bien. Je parle de bas de gamme dans ma conception des choses, je garde un ordinateur jusqu'à ce qu'ils soit hors d'usage ou définitivement inutilisable en raison de l'embonpoint des logiciels et les seules machines qui me tiennent plus de dix ans sans aucun problème sont aujourd'hui les Lenovo/Thinkpad et les Toshiba (y compris les disques). En étant un peu hors sujet, depuis 1991, j'ai eu comme pannes sur mon parc IBM/Lenovo/Toshiba (un nombre de machines permettant de commencer à faire des stats valables) : - une carte d'extension mémoire pour un PS/2 modèle P70; - un clavier pour un Toshiba Satellite 4060XCDT (machine qui fonctionne toujours); - un écran pour un Toshiba P200 1DE; - un support d'antivol cassé (sans doute par un utilisateur peu scrupuleux qui m'a dit que ça s'était cassé tout seul... À d'autres !...); - un bios complètement buggué sur une série de Lenovo non Thinkpad dont j'ai oublié la référence (de mémoire un Ideapad quelque chose). Ces machines sont gardées au moins cinq ans. Lorsque j'ai essayé Dell, plus de 50% du parc est passé en SAV sous garantie pour des problèmes de cartes-mères, de batteries et de chargeurs et de cartes mémoire pas compatibles mais presque... La joie de la qualité à pas cher. Quant à mon essai Acer (pas cher et jetable pour des gens qui ne prenaient pas soin de leur matériel), mieux vaut ne pas en parler. C'était vraiment du jetable ! Pour être tout à fait honnête cependant, il y a des choses exaspérantes dans les bios Thinkpad (des options qui ne font strictement rien dans le cas de mon Edge) mais pas aussi pénibles que pour les autres modèles où l'on a l'impression soit que ce n'est pas bien sec, soit que c'est voulu pour contraindre à l'utilisation de l'OS de Microsoft parce que tous les tests sont faits avec la dernière mouture de la microsofterie et que Lenovo se contrefout des autres utilisateurs. Le pire, ce sont les bugs grossiers qui sont remontés au support de Lenovo et qui ne sont jamais corrigés. Bien cordialement, JKB
