Comprar LA ATALAYA RECORTADA CONTRA EL CIELO (editorial Libros del Futuro)

Sinopsis:

Bran tuvo una adolescencia complicada, y su vida adulta no es mejor. Una sucesión de pérdidas familiares, una gran cicatriz en la cara y sus circunstancias personales han forjado en ella una personalidad esquiva.

Y como si fuera una maldición añadida, la protagonista hereda y debe hacerse cargo de una casa familiar, epicentro de buena parte de las desgracias que se abatieron sobre sus seres queridos.

Una visita a la enmohecida y arruinada vivienda, ubicada en un pequeño pueblo madrileño, sumergirá a Bran en una travesía angustiante por túneles oscuros, estancias claustrofóbicas y seres terroríficos.

It is obscene that governments effectively require people to have internet connectivity to be able to function in society but abdicate responsibility for ensuring that people actually have that and delegate it to for-profit enterprises instead

Does issuing an eject command to a USB flash drive make it spontaneously fly across the room?

Also applicable to other server software that need a lot of file descriptors for network connections or whatever.

Summary: increase the openfiles value in /etc/login.conf and the global kernel number with something like sysctl kern.maxfiles=20000.

The oft-forgotten, but useful tcpdrop(8) command accepted:

# tcpdrop 192.168.5.41 80 192.168.5.1 26747 # space

or...

# tcpdrop 192.168.5.41:80 192.168.5.1:26747 # colon

It now also accepts a 3rd syntax, compatible w/ netstat(1) output:

# tcpdrop 192.168.5.41.80 192.168.5.1.26747 # dot

Will this year give start to the era of "rewrite everything in Zig"?.

Daniel Stenberg, of the #curl tool and library fame, wrote not long ago an article [1] wondering if years in copyright notes are mandatory or not... His conclusion was to delete all year mentions. I'm not sure if he's right; I'm going to keep them by now (updating them, of course).

Thanks for your help.

Added support for #HashTags (they are not internally indexed yet, only propagated to other instances).

Added support for OpenBSD enhanced security functions unveil() and pledge() (contributed by alderwick).

The purge ttl for stray global objects has been shortened.

In the HTML interface, don't show the collapse widget for non-existent children.

Added support for HTTP signature pseudo-headers (created) and (expires), that are used by some ActivityPub implementations (e.g. Lemmy).

When replying, the mentioned people inherited from the original post will be clearly labelled with a CC: prefix string instead of just being dropped out there like noise like Mastodon and others do. (I hope) this will help you realise that you are involving other people in the conversation.

Perhaps this flood of content will prove beneficial [...]. But that outcome does not seem highly likely in the near future. Instead, we're likely to see code submissions from "developers" who do not understand what they are posting; this code could contain no end of bugs and, potentially, license violations. Cut-and-paste programming has long been a problem throughout this industry. It is far from clear that automating the cutting and pasting is going to improve the situation.

AI-generated text has its own challenges. Our mailing lists and forum sites do not lack for people trying to appear authoritative on subjects they do not really understand; how many more will show up when it is easy to get a machine-learning system to produce plausible text with little effort? Even the most ardent believers in the "last post wins" approach to mailing-list discussions will get tired and shut up eventually; automated systems have no such limits. How long until we have a discussion on, say, init systems that is sustained entirely by bots?

Your work is impressive. I love it.

First, add an option to automatically drop all announces (boosts). Unless your affinity with the people you follow is deep, boosts are just (usually) tangentially interesting, probably flooding your timeline and just forcing you to spend more and more time inside the social media space. A variant of this would be to make this option not global, but by actor, so that you can 'boost-mute' only those adorable but annoying fellows that are particularly trigger-happy to the boost button (implementing the option this way is more work for me, but not that much).

Second, add an option to drop all messages that are not public nor mentioning you. That is, filter out those infamous 'follower-only' messages. People use to engage in these follower-only conversations, so you only receive these chat fragments without context (unless you also follow all the people involved) and they are purely noise. In my opinion, follower-only messages are a very bad idea that just pollute the space (and this is why snac doesn't implement them and never will).

Third, add an option to drop all replies to your messages from people that you are not following. This would prove useful for very popular, mostly announce-only accounts. I agree that it's a bit elitist and probably toxic, but also helps in spending less time inside the social networks and more time painting or writing or taking the dog for a walk.

What do you think?

    value = user_value ? user_value : default_value;

What you may not know is that, thanks to a gcc (and others) extension, you can abridge that expression to this:

    value = user_value ?: default_value;

I find the article interesting not only for C++ "peeps", but for us greybeard C programmers as well, who learnt the language in the eighties. Remarkable sections in the document are:

- Use struct wrappers for strong typing (I've never done this, but it's interesting; accessing the components inside the structs may become a bit tedious, though).
- Initialization in C99 (I haven't used this to its full potential).
- Don’t be afraid to pass and return structs by value (as an old fart, I always pass pointers to structs, and this section reasons otherwise for small structs).
- Named optional arguments (or, as the author more accurately describes this, the "option bag").

Espero que os guste.

The m68 hand-written assembler version of strcmp() has always been broken: it returns the difference between the first non-matching byte done as a 8-bit subtraction.

That is _almost_ right, but is broken for the overflow case. The strcmp() function should indeed return the sign of the difference between the first byte that differs, but the subtraction needs to be done in a wider type than 'char'. Otherwise the ordering isn't actually stable.

Updated Debian 11: 11.6 released https://www.debian.org/News/2022/20221217

Fixed bug in message posting that may result in 400 Bad Request errors (contributed by tobyjaffey).

Fixed crash and a deletion error in the unfollow code.

Added configuration files and examples for running snac with docker (contributed by tobyjaffey).

Serve /robots.txt (contributed by kensanata).

Previous posts in the public and private timelines can be reached by a "More..." post at the end (contributed by kensanata).

Clicking the 'Like' and 'Boost' buttons don't move the full conversation up; after that, the page is reloaded to a more precise position. Still not perfect, but on the way.

New command-line operation, resetpwd, to reset a user's password to a new, random one.

Added a user setup option to toggle if sensitive content is shown or not by default (contributed by kensanata).

All images are loaded in lazy mode for a snappier feel (contributed by kensanata).

Fixed crash in the data storage upgrade process when debug level >= 2 (contributed by kensanata).

Log message improvements for excelence (contributed by kensanata).

The logging of "new 'Delete'..." messages has been moved to debug level 1, because I'm fed up of seeing my logs swamped with needless cruft.

Don't show the 'Boost' button for private messages.

Added (partial) support for /.well-known/nodeinfo site information. This is not mandatory at all, but if you want to serve it, remember that you need to proxy this address from your web server to the snac server.

Some internal structure improvements.

Interesting things: the overall simplicity and the chunk QOI_OP_LUMA, which implements diff compression from previous byte giving more weight to the green channel.

I'm experimenting this same thing with Firefox since upgrading to OpenBSD 7.2. Crashing also seem to match the timestamp of pledge "rpath" log messages. I had no time to investigate seriously so I'm not sure what is causing it (sure it's not Mastodon because I don't use it). I also didn't change anything in its global configuration. Also, the rofi tool is crashing 50% of the times I try to run it.

I'll try this weekend to find what it's happening.
