[Subversion] Meta data format version of the working copy

For all the versions (I think as of version 1.7) that store the meta data not any longer in files but in a SQLite database, the entries in .svn/format or .svn/entries are plainly wrong. They might be a left over of previous client versions.
You need to execute

PRAGMA user_version

against the working copy database .svn/wc.db.
You can do so with  DB Browser for SQLite or on the command line

sqlite3 .svn/wc.db "PRAGMA user_version"

I found this at https://stackoverflow.com/questions/19265363/find-out-svn-working-copy-version-1-7-or-1-8

Meta data format version	Client version
31	1.8.x
32	1.9.x

[jEdit] not-empty files files without text, files do not open without error

Symptoms

All of a sudden, not knowing what went wrong, I could not open any files any longer without getting an error; two files that were open, displayed no text even there ought to have be text. jEdit was utterly unusable.

Solution

I reverted to previous setting files set out of the settings-backup directory.

[Citrix Receiver/ICAClient] Windows 10 client very laggy

Symptom

The laptop to which I connect side is on Windows 7 but my local machine is on Windows 10. I previoulsy connected from the Linux client on various distributions and the connection just was fine. The notorious mouse pointer shadow is disabled and no theme on the laptop side.

"Cause"

It seems that Windows 10 handles TCP stuff espacially its windows size.

Try

playing around with the autotuning settings. By default it is set to normal.

netsh interface tcp set global autotuninglevel=disabled

netsh interface tcp set global autotuninglevel=highlyrestricted

netsh interface tcp set global autotuninglevel=restricted

netsh interface tcp set global autotuninglevel=normal

Details at https://technet.microsoft.com/en-us/library/cc731258(WS.10).aspx
Be aware, however, it might have negative impact on other TCP using applications!
However, this did not easen my pain with Citrix.

[Citrix Receiver/ICAClient] Connection dialog frozen

Setup

• Windows 10 Home
• dual screen setup (one on HDMI set to main by Windows settings, one on VGA of the onboard graphics)
• Citrix Receiver 4.8 (4.5, 4.6 and 4.7 sport the same behavior)
• Connection to Citrix session over web link downloaded in browser

Symptom

The Citrix Receiver process freezes at connection dialog and has to be kill by process management.

Work around

• Either use VGA screen as main screen
• Or deactivate VGA screen

Also

• Linux receiver at least 13.4 and 13.5 seems to be affected as well
