wake up sleep – MacBook Air crashes after closing the lid

I've noticed that my MacBook Air (13-inch, early 2015) restarts after sometimes opening the lid, indicating that it's crashed during sleep – can anyone decipher it? the error report attached and maybe give me an idea of ​​what's going on?

Thank you!

os – Oneplus 6 crashes in bootloop from Android 10

Since the update to Android 10, my oneplus 6 has a very annoying problem. From time to time, the phone suddenly stops and tries to restart. However, the phone does not restart, but continues to flash the screen in black, and then redisplay the startup screen. When I force the phone down while holding down the power button, the restart completes. Since then, I have removed all the apps I had installed since I started having problems and kept an eye on them, so I could maybe spot that which led to accidents. Since then, I have seen the phone crash several times and, most of the time, it is simply idle on my desk in front of me, when the screen suddenly displays the startup screen.

I then tried to find the logs on the phone, and after some research on Google, I discovered Logcat, then I emptied it into a txt file and I tried to l & # 39; explore. However, since I am not an Android developer, I really have no idea what to look for.

I was hoping that there is someone here who knows enough about these log files that maybe can give me hints about the next step.

Below you will find the result of the logcat, which I emptied about an hour after that happened. The accident occurred around 6:15 pm, but I unfortunately do not have the exact time. (The file was unfortunately too large for stackexchange and pastebin)

c ++ – Explicit loading of an Ogre3D DLL wrapper with linked OgreMainStatic.lib crashes when loading a mesh with CreateEntity

I have an Ogre3D 1.7.x DLL wrapper project that explicitly loads the Ogre functions and works properly using the OgreMain.dll + D3D9 Renderer plugin.dll that loads a mesh without any problems. This is my configuration:

MyWrapper.dll
OgreMain.dll
D3D9Renderer.dll

When I switched to using an OgreMainStatic.lib configuration, where it is now a single DLL installation (MyWrapper.dll ~ 5MB, linked and loaded lib plug-ins) and loading a Meshing with CreateEntity causes the application to crash.

I have tested the binding of my OgreMainStatic.lib on a single exe file, then loading a mesh and it works without any problem.

http://s000.tinyupload.com/index.php?file_id=49917179524872890232

Are there any changes or concerns in the way Ogre handles memory or threads when wrapping functions and explicitly loading a DLL against a DLL using Ogre Static Lib?

I've added an incident reporting tool to dump the error in question and generates an exception:

The thread tried to read or write to a virtual address for which
it does not have the appropriate access.

Both solutions always display the Ogre.log message that the mesh has loaded, but it hangs with the installation of the DLL linked to the static library:

drivers – the computer crashes when I watch videos

I have a dual boot and my computer hangs on Linux but not on Windows. This happens most of the time when you watch videos. I use Linux Mint 19 Cinnamon.

I suspect that he has something with my graphics cards. Under System information, it is written that I have as a graphics card Intel Core 4th Generation Integrated Graphics Controller while typing lspci j & # 39; I 01: 00.0 3D Controller: NVIDIA Corporation GM107M (GeForce GTX 960M) (rev a2)

This is probably related to overheating, but I do not know how to check that. How can I collect information after my next crash?

performance – MySQL 500% CPU utilization and server crashes

My dedicated server is a SATA XEON E3 hard drive 1240 V3 DDR3 1GB 8GB DDR3 (4 cores at 3.4 GHz), which I have only for a few days and that I just completed the migration of about 20 wordpress sites (each database of about 50 MB to 150 MB). in size). Mysqld has always used the processor more than 500% of its processor, which caused the blocking of the httpd service and prevented the loading of websites.

I have not yet changed the default my.cnf file, which looks like this:

#
# This group is read both both by the client and the server
# use it for options that affect everything
#

#

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
    Control warning line(s) into /var/lib/mysql/server1.nc-ph-0741-26.web-hosting.com.err file
    Control error line(s) into /var/lib/mysql/server1.nc-ph-0741-26.web-hosting.com.err file
    MySQL was started within the last 24 hours - recommendations may be inaccurate
    Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
    We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
             See https://dev.mysql.com/doc/internals/en/join-buffer-size.html
             (specially the conclusions at the bottom of the page).
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
    Performance schema should be activated for better diagnostics
Variables to adjust:
    query_cache_size (=0)
    query_cache_type (=0)
    query_cache_limit (> 1M, or use smaller result sets)
    join_buffer_size (> 256.0K, or always use indexes with JOINs)
    tmp_table_size (> 16M)
    max_heap_table_size (> 16M)
    table_definition_cache(400) > 1039 or -1 (autosizing if supported)
    performance_schema = ON enable PFS
    innodb_log_file_size should be (=16M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

What can I do to solve this problem?

WPA supplicant – Sudo crashes indefinitely after killing wpa_supplicant

I was trying to do a wifi test with a pen, so I should have killed a wpa_supplicant process. So I killed him and after that, I tried to run "sudo wpa_cli", but he only did hang my terminal, I tried Ctrl + C, but no result. If I open another tab, no matter what I type, but if it starts with sudo, my terminal is dead. I can not even run programs.

I am not sure if this happens because of wpa_supplicant or wifite or airmon, but I can say one thing, it is that I have already changed my hostname before.

mysql 5.7 – InnoDB errors and crashes in the MyISAM database?

I have a server with a mysql database containing only MyISAM tables. There are no other databases on the server (except those of the system of course). Since it's gone to mysql 5.7.27, there are errors related to InnoDB and even crashes. The configuration is mainly the default one provided with the Ubuntu 18.04 package, I just adjusted some buffers and the myisam cache. (Now, I've also increased the size of the innodb pool, hoping these mistakes will disappear)

What can cause these mistakes and how do I get rid of them?

Examples of errors:

2019-09-19T04: 39: 34.464347Z 5169718 (Warning) InnoDB: Difficult to find free blocks in the buffer pool (21 search iterations)! 21 unsuccessful attempts to empty a page! Consider increasing the size of the buffer pool. It is also possible that in your version of Unix, fsync is very slow or completely stuck in the core of the operating system. Then upgrading to a newer version of your operating system can be helpful. Look at the number of fsyncs in the diagnostic information below. Pending dumps log (fsync): 0; buffer pool: 0. 22967494 operating system file readouts, 55308825 operating system file writes, operating system 1252 fsyncs. Start InnoDB Monitor to print other diagnostics on the standard output.
