Reset file associations to newer versions of Windows 10 to application standards

In previous versions of Windows 10, it was possible to restore the default mappings that an application would normally have. For example, I was able to authorize MS Word for all the shortcuts that MS Word would normally set as default, even if they were assigned to other applications in the meantime. More importantly, this was possible even in cases where the associations were all right.

I don't seem to be able to find this option in newer versions of Windows 10. Yes, I can set "file type and protocol mappings" per app, but there doesn't seem to be a way to reset these mappings, i.e. H. To rewrite. Is this functionality completely gone or difficult to find?

In particular, I feel this is necessary because with MS Word everything is selected in the list of file types and protocol assignments and everything seems to be in order. However, MS Word complains every time it opens a * .doc file that it is not set as the default application for the file type. Obviously something is wrong. I think reinstalling or repairing would solve the situation as well, but resetting file associations was the easier solution in such cases.

DELL Optiplex 9010 Problem displaying movies on newer kernels

I have problems with the display of motion pistols (videos, but also scrolling). It appears that some parts of the screen are updated at different times than the others. Most of the time, the border between two parts is 1/3 of the screen horizontally, then drops off for 1/3 of the screen and then continues horizontally. Here's a link to a video (though I'm not sure if it caused the symptom or only I see it because of my system performance 🙂

EDIT: Sorry, I think the video fails, once it appears, another time not. I leave it, as I begin to doubt my own senses 🙂

Hardware:
I have tried different monitors and cables. I started with a 2560×1080 monitor, as you can guess from the video, and initially thought it was the cause of the problem, but then switched to a 1920×1080 monitor, and it's the same thing.
I am using a DELL Optiplex motherboard with integrated graphics. Everything I found on the board is:
c us

DP / N

CN 051FJ8-72200
29G-02N8-A00

Software (everything is x64):
The problem occurs:
– Ubuntu Mate 4.15 generic, 4.19 generic
– regular Ubuntu-18.04.3 (also 4.15-generic)

I found this thread:

The Ubuntu 14.04 LTS screen flickers on the Dell Optiplex 9010 AIO system.

So I tried Ubuntu-14.10 because it has a 3.16 kernel that is close to the 3.15 kernel recommended in the thread. This solved the problem, but for some reasons the system is super slow and of course has security issues.

macos – Can you boot to recovery mode on a legacy iMac with a newer version of OS X (10.8)?

I am using OS X 10.8 on a 2008 2008 iMac and apparently can not enter recovery mode. Command-r does not matter – the computer just boots normally every time. Although OS X 10.8 certainly supports recovery mode, I wonder if the problem might be that I am using an iMac that was created before the feature was added to OS X (my iMac was added in 2011 with 10.7 Lion) as of 2008 ). Is it possible that the hardware prevents me from booting into recovery mode, or is this just a function of the operating system and should work on older iMacs as well?

Used Canon 80D or newer 250D

I'm looking forward to a pretty good second-hand secondhand 80D for £ 500 (body only). This is a good discount compared to a brand new 80D, but I wonder how it compares to a 250D. I can buy this new lens for the same price (with a Canon EF-S 18-55mm f / 4-5.6 IS STM lens).

The main disadvantages of the 250D are: slightly smaller sensor (332 mm 2 compared to 338 mm 2), lower maximum value for continuous shooting (5 vs. 7 frames per second).

This will be my first DSLR. I think that the 250D was placed in a lower price category but the time between releases (3 years) means that the 250D is basically as good as the 80D, but in this case the brand is new and it can Process 4K video and is much easier. (The two main advantages I see in it).

How do I get a newer version of a package for 18.04?

I have one more question opensmtpd on Ubuntu 18.04 …

apt-get install opensmtpd

… installs the version 6.0.3p1-1build1who has a problem:

The systemd opensmtpd.service that seems to be thinking ExecStop=/usr/sbin/smtpctl stop stops the service. however smtpctl stop Returns a nonzero exit code, and the output indicates that the subcommand is unknown:

possibilities are:
discover
encrypt
pause
resume
show
log
monitor
profile
remove
schedule
trace
uncorrupt
unprofile
untrace
update

I notice that this issue has been detected and fixed in versions 6.0.3p1-2

That was in March 2018, well over a year and a half ago.

I see newer versions for Ubuntu 18.10 and 19.04 are being installed. So how can it be that these and newer versions have not made it to 18.04 since then?

How could that happen?

If I update the Play Store to a newer version using an APK, will the Play Store automatically update if an even newer version is available?

The Play Store app on my phone takes longer than other phones to get the latest version. So I've updated it to the latest stable build with an apk. I'm wondering if, after updating the Play Store with an apk, I get updates for even newer versions. For example, if it was previously at 10.1 and I upgraded to 10.2 with an APK, it will update itself if 10.3 is available for download for my particular device model (or in other words, if other handsets of the same model) becomes 10.3 Version, will I get it too?)

How do I import database data to a new host running a newer version of MySQL without SSH access?

My current host for an old website only has MySQL 5.0
(serverVersion = 10.2.12-MariaDB-log).

I'd like to move this site to a host running MySQL 5.5 or 5.6 or 5.7 (depending on which server I move to).

The only instructions I can find for updating database data from 5.0 to 5.6 / 5.7 are executed from the command line and require ssh access that I do not have.

I usually use MySQL Workbench to connect to remote databases, but when I connect The old host through MySQL Workbench, a message appears with the inscription [Workbench] is not compatible with 5.0.
So I either use the MySQL Workbench for this host to back up (which probably means the backup is not good), or I use the host's web-based tool (better idea, but not my preference).
I also recently installed HeidiSQL as it seems to be compatible with 5.0 (I will not give any warning / error anyway). So I'll start making backups with HeidiSQL.

The only reason I continue to use the host with MySQL 5.0 is because I have not found any instructions on how to migrate data for sites on this server, whether through a hosting provider's online database tool, MySQL Workbench or HeidiSQL!
All I see is that you can do step-by-step data updates from the command line and / or update the database server itself.

I need a way to update the data from 5.0 to 5.6 or 5.0 to 5.7, probably in one step, with a GUI database connection tool or some other independent method.
I do not have access to mySQL servers other than the server I'm migrating from (5.0) to the server I am migrating to (5.5 or 5.6 or 5.7).

Does anyone know how to do that?

Encryption – Is it still inadvisable to use newer versions of EncFS> 1.7 to encrypt Dropbox?

I want to use EncFS to encrypt files synced with Dropbox. Unfortunately, the Wikipedia page https://en.wikipedia.org/wiki/EncFS mentions security concerns from a version 1.7 audit:

EncFS is not sure if the opponent has the opportunity to see two or more snapshots of the ciphertext at different times.

Somebody with access to my Dropbox account does just that: Dropbox saves several earlier versions of a file after it's been modified. These are exactly "two or more snapshots of the ciphertext at different times".

For example, in 2015, this was confirmed in the following question: Is ENCFS safe for Dropbox encryption?


With regard to version 1.8, it says in Wikipedia:

The EncFS 1.8 announcement included several underlying design changes to address the security concerns raised during the previous review. However, there are still some concerns about these vulnerabilities.

What concerns remain? Is the problem with Dropbox fixed?

According to https://github.com/vgough/encfs/releases the latest version is 1.9.5.

Is it still inadvisable to use the latest versions of EncFS to encrypt Dropbox? Is there still a problem with "two or more snapshots of the ciphertext at different times"?

Are there any newer models that still fit with my Canon XTi underwater case?

I'd like to upgrade my Canon XTi with a newer Canon model that fits into my DX400D Sea and Sea underwater case.

I would like to have a "newer" Canon model that …

  1. Has the same key layout on the back and the top should be the same as the XTi
  2. Has "live preview", so I can frame the picture with LCD instead of the small viewfinder.
  3. Has video recording
  4. Lets me keep using my old CANON EFS 18-55 and a TOKINA 10-17 DX AT-X lens.

Authentication – Can I sign with two code signing certificates to improve the reputation of the newer ones?

I recently purchased a Microsoft Authenticode code signing certificate as a renewal of another certificate that is about to expire.

Obviously, the new certificate is not assigned a reputation, and it will take some time and it will be installed to be fully trusted.

My question is: If I sign an executable with both Certificates, will build the new reputation?

I've already checked if the installer trusts if both signatures exist.
