USB 3.0 in the year 2020

In the year 2011 I wrote about USB 3.0 for the first time. A few years later again (USB 3.0 today). Meanwhile it is 2020 and a current benchmark of a SanDisk Extreme Pro with 128 GB. To have comparable values again with “HD Tune” but this time with Windows 10.

The hardware used for the test is still the same mainboard which I’ve been using since 2014.

Looking back the values of earlier tests which show the impressive development of about 20 year:

Storage media Read speed
M-Sys DiskOnKey 128 MB (USB 1.1) 0.9 MB/s
Sony 8 GB (USB 2.0) 15.2 MB/s
Verbatim Store N Go 16 GB (USB 3.0) 122.4 MB/s
SanDisk Extreme Pro 128 GB (USB 3.0) 209.6 MB/s

Search with results in real time

From now on my website provides a search function with results in real time which are displayed as list below the search input. For this I developed a plugin for WordPress which uses the Ajax interface and runs the search while text is entered.

Yes, there are already plugins for this – but the implementation was not too difficult (about 190 lines of code) and I learned something about using Ajax with WordPress.

One thing missing is a good keyboard navigation, but this will propably be added as well. For now you can navigate using the [Tab] key.

Using the keyboard is also possible – with the tab key (or the key your browser uses for changing the focus) you can change from the search input to the result list and move between the entries in the list. The kursor keys  up and down ([↓] / [↑]) can also be used for navigation. To open an entry, press return ([↵]) or [enter]. With [Esc] the result list will be closed without opening an entry.

Spamfilter and DKIM with rspamd

Recently a major update of the server enviroment was needed on which I also run a mail server. I took this as an opportunity to try rspamd as alternative to the combination of SpamAssassin and amavisd-new and can fully recommend this.

Main features of rspamd:

  • Web UI with status information and for easy configuration changes.
  • Up to 10× faster than SpamAssassin (also see the explanation at rspamd).
  • Direct integration as milter in Postfix which allows to scan e-mail during delivery so they can actively rejected or delayed using greylisting if needed.
  • Optional DKIM signatures for outgoing e-mail.

Nextcloud and Netdata

I’ve been using Netdata on my servers to monitor many system parameters for quite a while now. What missed so far is Nextcloud. I filled this gap with a plugin for Netdata. The plugin uses the API which is provided by the “Monitoring” app to display the number of active users.

You get the source and description at Github.

Nextcloud and OnlyOffice in Android

As reported at OnlyOffice, you can now also use OnlyOffice in Android with Nextcloud, although you do not need a separate app for Android – it is part of the current Nextcloud app for Android. On the server you need at least Nextcloud 18 and the latest OnlyOffice integration for Nextcloud (4.1 or newer). OnlyOffice also runs collaboratively in the same way as in the browser – all changes are sent directly to the server and if other users are also editing a file at the same time, their changes can be seen immediately.

However, there is one thing to note:

If the file has not yet been downloaded (no green check mark), tapping the file name will open it in OnlyOffice. If the file already exists on the device (green check mark), it is opened directly when tapped – i.e. if an another office app is installed on the device, that app will be used to view or edit the file.

In addition, you can also use the context menu, which opens when you tap the three dots on the far right and then select “Edit”. In this case the file is always opened with OnlyOffice.

Update 2020-03-09

The free open source version does not provide editing functions any longer – neither in the app nor in the browser. If you need this, you have to buy on of the packages of the “Integration Edition” (currently beginning at 935 EUR one time payment per server for a maximum of 50 concurrent connections).

Update 2020-03-20

After I created a feature request at Github to get back the mobile editing or at least a cheaper license for private and home users, Ascensio decided to offer a cheaper “Home” license for 99 USD. Also see the comment at Github.

Update 2020-09-02

The free Android version of OnlyOffice have been supporting using Nextcloud to open and save documents for a while now and is more comfortable to use than the version in the browser. The only limitation is that this version does not support the collaborative functions.

We are all humans

On February 19, 2020, 10 people were murdered in Hanau by a man for racist reasons.

I would like to express my sympathy to the relatives, friends and colleagues of the victims and wish them the strength to cope with this bad time.

In reports there was also a brief reading of “Shisha-Morde” at Focus and as reported on, the Bild newspaper first found in its live reporting that the victims are mostly Kurdish and Turkish people and spread wild speculation that the perpetrators were people from the “Russian sphere” and that extortion of protection money was possibly a reason for the murders.

No, there weren’t any Russians involved and no, it wasn’t about extortion!

Presenting the murders in this way and spreading such speculation is a gross disregard for the dignity of the victims! Such speculations pretend that the murdered are virtually to blame themselves, because as a visitor of a shisha bar one must expect that acts of violence will also take place there and that all those involved come from a “Milieu” in which such acts are quite conceivable.

Stop it!

Humans have died – humans like you and me. Help those who are affected, show solidarity with your fellow citizens and stop to put people with a migration background to a box with which you personally have nothing to do.

New year, new illegal copy of Periodical

New year, new scroungers who think they can easily make money from my work. Again an illegal copy of Periodical with plenty of advertising, published at (February 11, 2020. If this URL is no longer available, it has already been deleted):

As usual there are no sources available and every reference to the original source was removed.

Update 2020-03-25

Meanwhile Google responded to my notice and the app was removed :-).
