+Perhaps it's time to think about non-copyright mitigations. Here is an easy

+Powershell and nushell take unix piping beyond raw streams of text to
+structured or typed data. Is it possible to keep a traditional shell
+like bash and still get typed pipes?
+
+I think it is possible, and I'm now surprised noone seems to have done it
+yet. This is a fairly detailed design for how to do it. I've not
+implemented it yet. RFC.
+
+Let's start with a command called `typed`. You can use it in a pipeline
+like this:
+
+	typed foo | typed bar | typed baz
+
+What `typed` does is discover the types of the commands to its left and its
+right, while communicating the type of the command it runs back to them.
+Then it checks if the types match, and runs the command, communicating the
+type information to it. Pipes are unidirectional, so it may seem hard
+to discover the type to the right, but I'll explain how it can be done
+in a minute.
+
+Now suppose that foo generates json, and bar filters structured data of a
+variety of types, and baz consumes csv and pretty-prints a table. Then bar
+will be informed that its input is supposed to be json, and that its output
+should be csv. If bar didn't support json, `typed foo` and `typed bar`
+would both fail with a type error.
+
+Writing "typed" in front of everything is annoying. But it can be made a
+shell alias like "t". It also possible to wrap programs using `typed`:
+
+	cat >~/bin/foo <<EOF
+	#/usr/bin/typed /usr/bin/foo
+	EOF
+
+Or program could import a library that uses `typed`, so it
+natively supports being used in typed pipelines. I'll explain one way to
+make such a library later on, once some more details are clear.
+
+Which gets us back to a nice simple pipeline, now automatically typed.
+
+	foo | bar | baz
+
+If one of the commands is not actually typed, the other ones in the pipe will
+treat it as having a raw stream of text as input or output.
+Which will sometimes result in a type error (yay, I love type errors!), 
+but in other cases can do something useful.
+
+	find | bar | baz
+	# type error, bar expected json or csv
+	
+	foo | bar | less
+	# less displays csv 
+
+So how does `typed` discover the types of the commands to the left and
+right? That's the hard part. It has to start by finding the pids to its
+left and right. There is no really good way to do that, but on Linux, it
+can be done: Look at what `/proc/self/fd/0` and `/proc/self/fd/1` link to,
+which contains the unique identifiers of the pipes. Then look at other
+processes' `fd/0` and `fd/1` to find matching pipe identifiers. (It's also
+possible to do this on OSX, I believe. I don't know about BSDs.)
+
+Searching through all processes would be a bit expensive (around 15 ms with
+an average number of processes), but there's a nice optimisation: 
+The shell will have started the processes close together in time, so the
+pids are probably nearby. So look at the previous pid, and the next
+pid, and fan outward. Also, check `isatty` to detect the beginning and end
+of the pipeline and avoid scanning all the processes in those cases.
+
+To indicate the type of the command it will run, `typed` simply opens
+a file with an extension of ".typed". The file can be located
+anywhere, and can be an already existing file, or can be created as needed
+(eg in `/run`). Once it discovers the pid at the other end of a
+pipe, `typed` first looks at `/proc/$pid/cmdline` to see if it's
+also running `typed`. If it is, it looks at its open file handles
+to find the first ".typed" file. It may need to wait for it the file handle
+to get opened, which is why it needs to verify the pid is running `typed`.
+
+There also needs to be a way for `typed` to learn the type of the command
+it will run. Reading `/usr/share/typed/$command.typed` is one way.
+Or it can be specified at the command line, which is useful for wrapper scripts:
+
+	cat >~/bin/bar <<EOF
+	#/usr/bin/typed --type="JSON | CSV" --output-type="JSON | CSV" /usr/bin/bar
+	EOF
+
+And `typed` communicates the type information to the command that it runs.
+This way a command like `bar` can know what format its input should be in,
+and what format  to use as output. This might be done with environment
+variables, eg `INPUT_TYPE=JSON` and `OUTPUT_TYPE=CSV`
+
+I think that's everything `typed` needs, except for the syntax of types and
+how the type checking works. Which I should probably not try to think up
+off the cuff. I used Haskell ADT syntax in the example above, but don't
+think that's necessarily the right choice.
+
+Finally, here's how to make a library that lets a program natively support
+being used in a typed pipeline. It's a bit tricky, because it has to run
+`typed`, because `typed` checks `/proc/$pid/cmdline` as detailed above. So,
+check an environment variable. When not set yet, set it, and exec `typed`,
+passing it the path to the program, which it will re-exec. This should
+be done before program does anything else.

 ## Vipe with arguments for editor commands involving whitespaces
 
 I sometimes want to use vipe while passing arguments to my editor (let’s say `vim +startinsert`).  That’s easy enough, I just need to run it with the EDITOR variable locally set to that.  But if the arguments contain whitespaces (for instance `vim -c 'norm o'`), this trick doesn’t work anymore, because the EDITOR variable is split on whitespaces.  For that purpose, it would be nice to check as a last case after EDITOR and VISUAL whether any arguments have been passed to vipe and, if that is the case, to set `@editor` to `@ARGV`.  We could then do `vipe vim -c 'norm o'` for those cases that require more flexibility. --Vej Kse

+I don't think that there is no need to backup content from Github anymore - in contrary, developers are aware that Github can change their policies at any time and if that happens, their content might be gone, so they do make a backup.
+
+Now that you announced github-backup as withdrawn, I can recommend another tool which seems to aim for the same target as yours: [python-github-backup](https://github.com/josegonzalez/python-github-backup). It seems to do the job of backing up the metadata quite nicely.
+
+I use it in conjunction with a more basic approach of cloning/pulling each repository itself like this:
+
+    function doBackup {
+        URL=$1
+        REPO=$(echo $URL | sed -e 's#^.*/##g' -e 's#.git$##')
+        
+        if [ -d $TARGET_REPOS/$REPO ]; then
+            cd $TARGET_REPOS/$REPO
+            git pull --all >/dev/null
+        else
+            echo \"cloning $REPO\"
+            cd $TARGET_REPOS
+            git clone $URL >/dev/null
+        fi
+    }
+    curl -s 'https://api.github.com/users/mathisdt/repos?type=owner&per_page=500' \
+        | grep -Eo '\"git_url\": \"[^\"]+\"' \
+        | sed -e 's#\"git_url\": ##' -e 's#\"##g' \
+        | while read url; do doBackup $url; done

+I am no longer maintaining [github-backup](http://github-backup.branchable.com/).
+I'll contine hosting its website and git repo for the time being, but it needs
+a new maintainer if it's going to survive.
+
+I don't really think it needs to survive. If the farce of youtube-dl being
+removed from github, thus losing access to all its issues and pull
+requests, taught us anything, it's that having that happen does not make
+many people reconsider their dependence on github. (Not even youtube-dl it
+turns out, which is back on there.) Clearly people don't generally
+have any interest in backing that stuff up.
+
+As far as the git repositories on Github, they are getting archived very
+effectively by [softwareheritage.org](https://softwareheritage.org/)
+which vaccumes up all git repositories from Github. Which points to a
+problem, because the same can't be said for git repositories not hosted on
+Github. There's a
+[form to submit them](https://archive.softwareheritage.org/save/)
+but the submissions often get hung up needing manual review, and it doesn't
+seem to pull in new commits actively if at all, based on the few git
+repositories I've had archived there so far.
+
+That seems like something it might be worth building some software to manage.
+But it's also just another case of Github's mass bending reality around it;
+the average Github user doesn't care about this and still gets archived;
+the average self-hosting git user may care about this slightly more, but most
+won't get archived, even if that software did get built.

+## Vipe with arguments for editor commands involving whitespaces
+
+I sometimes want to use vipe while passing arguments to my editor (let’s say `vim +startinsert`).  That’s easy enough, I just need to run it with the EDITOR variable locally set to that.  But if the arguments contain whitespaces (for instance `vim -c 'norm o'`), this trick doesn’t work anymore, because the EDITOR variable is split on whitespaces.  For that purpose, it would be nice to check as a last case after EDITOR and VISUAL whether any arguments have been passed to vipe and, if that is the case, to set `@editor` to `@ARGV`.  We could then do `vipe vim -c 'norm o'` for those cases that require more flexibility. --Vej Kse

+My inverter has unfortunately died, and I wanted to replace it with the
+same model. Ideally before I lose the contents of the fridge. It's a 24v
+inverter, which is not at all as easy to find a replacement for as a 12v
+inverter would be.
+
+Somehow Walmart was the only retailer that 
+[had it available](https://www.walmart.com/ip/AIMS-Power-1500-Watt-48-Volt-Pure-Sine-Inverter/35887513)
+with a delivery estimate: Just 2 days.
+
+[[!img pics/shipping/walmart.png]]
+
+It's the second day now, with no indication they've shipped it. 
+I noticed the "sold and shipped by Zoro", so went and
+[found it on that website](https://www.zoro.com/aims-power-pure-sine-inverter-1500w-24v-pwri150024s/i/G4430015/).
+
+[[!img pics/shipping/zorro.png]]
+
+So, the reality is it ships direct from China via container ship. As does
+every product from Zoro, which all show as 2 day delivery on Walmart's website.
+
+I don't think this is a pandemic thing. I think it's a trying to compete
+with Amazon and failing thing.
+
+----
+
+My other comically bad shipping estimate this pandemic was from Amazon
+though. There was a run this summer on Kayaks, because social distancing is
+great on the water. I found a high quality inflatable kayak.
+
+Amazon said "only 2 left in stock" and promised delivery in 1 week.
+One week later, it had not shipped, and they updated the delivery
+estimate forward 1 week. A week after that, ditto.
+
+Eventually I bought a new model from the same manufacturer, Advanced
+Elements. Unfortunately, that kayak exploded the second time I inflated it,
+due to a manufacturing defect.
+
+So I got in touch with Advanced Elements and they offered a replacement. I
+asked if, instead, they maybe still had any of the older model of kayak
+I had tried to order. They checked their warehouse, and found
+"the last one" in a corner somewhere.
+
+No shipping estimate was provided. It arrived in 3 days.

   On first inspection with `pee md5sum sha256sum` vs `pee sha256sum md5sum`, and on a fast/idle machine, it looks like stdout are collected and then written.

+## Vipe without stdin
+
+Hi Joey, thanks for your work on moreutils. I use vipe all the time. As someone else said, this is the killer app :)
+Sometimes I would like to use vipe without receiving any input first, so that I can set up some text for piping to another program. Kind of like here-docs or echo, except you get to edit the text with vim first. A simple example could look something like this:
+
+    vipe | wc -c
+
+More often, I might want to do something like this:
+
+    vipe | datamash sum 1
+
+Now, vipe can *sort of* do this, by using either a here-string (`vipe <<< "" | wc -c`) or by pressing Ctrl-D as soon as vipe launches. I wondered if we could just skip the Ctrl-D step and have vipe detect when no stdin has been given to it; instead, jump straight into an empty vim document? - TR

+
+When a unix process is running in a directory, and that directory gets
+renamed, the process is taken on a ride to a new location in the
+filesystem. Suddenly, any "../" paths it might be using point to new, and
+unexpected locations.
+
+This can be a source of interesting behavior, and also of security holes.
+
+Suppose root is poking around in `~user/foo/bar/` and decides to 
+`vim ../../etc/conffile`
+
+If the user notices this process is running, they can `mv ~/foo/bar /tmp`
+and when vim saves the file, it will write to `/tmp/bar/../../etc/conffile`
+AKA `/etc/conffile`.
+
+(Vim does warn that the file has changed while it was being edited. Other
+editors may not. Or root may be feeling especially BoFH and decide to
+overwrite the user's changes to their file. Or the rename could perhaps be
+carefully timed to avoid vim's overwrite protection.)
+
+Or, suppose root, in the same place, decides to archive `../../etc` with tar,
+and then delete it:
+
+	tar cf etc.tar ../../etc; rm -rf ../../etc
+
+Now the user has some time to take root's shell on a ride, before the
+`rm` starts ... and make it delete all of `/etc`!
+
+Anyone know if this class of security hole has a name?

+I've been digging into async exceptions in haskell, and getting more
+and more concerned. In particular, `bracket` seems to be often used in ways
+that are not async exception safe. I've found multiple libraries with problems.
+
+Here's an example:
+
+	withTempFile a = bracket setup cleanup a
+	  where
+		setup = openTempFile "/tmp" "tmpfile"
+		cleanup (name, h) = do
+			hClose h
+			removeFile name
+
+This looks reasonably good, it makes sure to clean up after itself even
+when the action throws an exception.
+
+But, in fact that code can leave stale temp files lying around.
+If the thread receives an async exception when `hClose` is
+running, it will be interrupted before the file is removed.
+
+We normally think of `bracket` as masking exceptions, but it
+doesn't prevent async exceptions in all cases.
+See [Control.Exception on "interruptible operations"](http://hackage.haskell.org/package/base-4.14.0.0/docs/Control-Exception.html#g:13),
+which can receive async exceptions even when other exceptions are masked.
+
+It's a bit surprising, but `hClose` is such an interruptable operation,
+because it flushes the write buffer. The only way to know is to
+[read the code](https://hackage.haskell.org/package/base-4.14.0.0/docs/src/GHC.IO.Handle.Internals.html#hClose_help).
+
+It can be quite hard to determine if an operation is interruptable, since
+it can come down to whether it retries a STM transaction, or uses a MVar
+that is not always full. I've been auditing libraries and I often have
+to look at code several dependencies away, and even then may not be sure
+if a library has this problem.
+
+* [process's withCreateProcess](https://github.com/haskell/process/issues/183)
+  could fail to wait on the process, leaving a zombie. Might also leak
+  file descriptors?
+
+* [http-client's withResponse](https://github.com/snoyberg/http-client/issues/436)
+  might fail to close a network connection. (If a MVar happened to be empty
+  when it's called.)
+
+  Worth noting that there are plenty of examples of using http-client
+  to eg, race downloading two urls and cancel the slower download. Which 
+  is just the kind of use of an async exception that could cause a problem.
+
+* persistent's withSqlPool and withSqlConn might fail to clean up,
+  when used with persistent-postgresql. (If another thread is using the
+  connection and so a MVar over in postgresql-simple is empty.)
+
+* concurrent-output has some locking code that is not async exception safe.
+  (My library, so I've fixed part of it, and hope to fix the rest.)
+
+So far, around half of the libraries I've looked at, that use `bracket`
+or `onException` or the like probably have this problem.
+
+What can libraries do?
+
+* Document whether these things are async exception safe. Or perhaps
+  there should be an expectation that "withFoo" always is, but if so the
+  Haskell comminity has some work ahead of it.
+
+* Use `finally`, eg
+
+	hClose h `finally` removeFile name
+
+  Good mostly in simple situations; more complicated things would be hard
+  to write this way.
+
+* Use `uninterruptibleMask`, but it's a big hammer and is often not the
+  right tool for the job. If the operation takes a while to run,
+  the program will not respond to ctrl-c during that time.
+
+* May be better to run the actions in worker threads, to insulate
+  them from receiving any async exceptions.
+
+	bracketInsulated :: IO a -> (a -> IO b) -> (a -> IO c) -> IO c
+	bracketInsulated a b = bracket
+		(async a >>= wait)
+		(\v -> async (b v) >>= wait)
+
+My impression of the state of things now is that you should be very cautious
+using `race` or `cancel` or `withAsync` or the like, unless the thread is small
+and easy to audit for these problems. Kind of a shame, since I had wanted to
+be able to cancel a thread that is big and sprawling and uses all the
+libraries mentioned above.

+
+\"Articles are not considered a navigational landmark, but many assistive technologies that support landmarks also support a means to navigate among articles. ...\"
+
+\"header\" elements are turned into navigational landmarks when they are descendants of the \"body\" element and this type of landmark is the \"banner\". They are the converse of a \"footer\" element which transform into \"content info\" landmark when it is directly child of \"body\". As navigational landmarks they are just meant for the whole page and not for individual sections of the page.
+
+In Section 4.1 of [WAI-ARIA Authoring Practices 1.1](https://www.w3.org/TR/wai-aria-practices-1.1/#bib-html-aria) is described which HTML semantic region elements get turned into aria landmarks.
+
+Finally, headings are what most screen readers go to first for navigation of a web page. So for those reasons I'd recommend making the article titles headings. If you don't want to literally make them a \"h1-6\" because it would mess with your CSS then you can just set aria attributes which will change how the page is understood by assisstive tech but not affect any visual rendering of the page.

+Sectioning using <article> is helpful, as they provide semantics about the web page layout, but they are not considered to be a navigational landmakr, so not all screen readers support navigating by <article> sections.

+@samuel.kacer, the sections of the blog are inside html article tags,
+and the heading of each is inside a html header tag.
+That seems like sufficient semantic information to me..
+
+I guess what I'll suggest is, if there's some reason that's not sufficient,
+you file a bug report on <https://ikiwiki.info> which is what the blog
+uses.

+Hi,
+
+I just stumbled onto your blog yesterday while searching for information on FRP in Haskell. Really cool stuff using Haskell for home automation in embedded systems!
+
+I just wanted to post a comment because I noticed you include nice alt text on your images, which I greatly appreciate as a blind person. One other note on accessibility is that navigating around your blog would be easier if the article headings were some sort of HTML heading like <h2>. Screen readers give shortcuts for jumping between different headings, so having sections of a webpage of intrest start with headings means as a screen reader user I could very easily switch between them instead of scrolling  through the whole article before finding the beginning of the next one.
+
+Just thought I would mention it since it seems you already care about accessibility.
+
+Oh and happy late birthday!
+
+Regards,
+Sam
