Intel i7-10750H, i7-9750H are very potent CPUs but laptops with them tend to run on the hot side. Did Intel meant H for Hot? Of course you may need some time to cool off from gaming or rendering or whatever demanding tasks are. For casual web-browsing, watching Youtube videos, simple office works, you probably don't need all the computation power, nor all that noise and heat. In case of those H-series laptops switching Power mode to "Better battery life" unfortunately is not enough. The solution I found for myself is to addition to going with the "Better battery life" even on AC, is to reduce maximum processor frequency, let Windows park more cores, and stick to the Passive cooling policy. Reducing max frequency, also may reduce coil whine as a nice bonus :-) Convertibles like Lenovo Yoga 940, HP Spectre x360 have Processor power management disabled by default. The reason is unknown to me, but necessary adjustments still work, and that's all that matter. Here comes the usual disclaimer, that whatever you do with your computer is on your own risk, and I am not responsible for anything you get using instructions below. Please make sure you do have backup of your MS Windows registry, you will need it to revert your changes. 1. Make sure you are not running high performance mode in HP settings: In "HP Command Center" select "HP Recommended" 2. Make sure the Power mode is set to "Better battery life": On Windows taskbar click battery icon, select "Best battery life" 3. To enable Power profile adjustments for CPU just download and launch registry file - http://loc2log.ucoz.com/power_management.reg. It will enable parameters discussed below, but it will not set any values - that is totally up to you, how much performance to cut for sake of quietness and temps. 4. After the registry file execution, on in taskbar, right click on battery icon, select "Power options", "Create a power plan". 5. Put whatever you like in plan name, e.g. "Cool", click "Create". 6. On the newly created plan, click "Change plan settings", then "Change advanced plan settings". 7. Locate, "Processor power management" and tweak enabled parameters to your liking. The following configuration pretty much eliminated heat and noise in my case on both HP Spectre x360 with i7-10750H and Lenovo Yoga c940 15.6" UHD (all for both, "On battery" and "Plugged in"). The Yoga was not as quiet as the Spectre though.
8. Click "Apply", give the computer some time to cool-off, then try some of your "non-demanding" tasks. Adjust parameters as necessary 9. Click "Ok" to keep the parameters. Now you should be able to run cool and quiet with just switching to the newly created power profile: On the taskbar right click on battery and select your "Cool" profile. Enjoy the silence ;-)

So you've got a bigger and better card than an existing one in your Android 7.1.1 phone. You may have already copied files form your old card to the new one, but some apps are failing to find their files in the new card. The reason is that mount point for the new card is different from the old one so the actual path the app is different from what is expected by the app. The trick is, to change your new SD card's Volume Serial Number. Here is what I did to upgrade SD card in storage mode using MS Windows 8: Prerequisite: Download VolumeId tool from VolumeId at MS KB. Unzip it. Full procedure steps for Android 7.1.1 SD storage card
Congratulations, your apps should see all their files now, as nothing happened :-) |

When I entered one of my server instances on DigitalOcean via ssh I was shocked to discover there were almost half-million unsuccessful login attempts. That was definitely a cracking attempt going on. And I must confess my setup was not the strongest. So here are the remedy options:

I have CentOS 7.0 iso set used as CD/DVD in VMWare, and wanted to use the image as the source to install rpms to my VMWare instance. It appeared quite easy to do:
That is pretty much it, yum shall be able to pick up your "CD/DVD" iso just as the other repositories. |
Recently I was debugging quite a convoluted bunch of daemons. That was an integration task with the goal to set proper permissions on temporary files used by them. I had to know what daemon is trying to access a certain file, and what user and group memberships are active for the daemon. There is a bunch of ways how to check what is accessing a file on Linux. The audit seemed to be the the most suitable one, as I did not know the exact timing for the access events. Get things going I had to hook up a non-core repo on my CentOS 6.8 machine. Then to install audit with: sudo yum install audit
Then start the daemon: sudo service auditd start
Checked the audit daemon is actually running: sudo service auditd status
Added the monitored rule: auditctl -w /path/to/my/file -p rawx
The -w parameter sets which file or dir to monitor. If a directory is given, then all files and sub-dirs are going to be monitored. The -p parameter enforces what exactly to monitor. I threw it all: r - for read, a - for append, w - for write, x - for execute. The output can be found in /var/log/audit.log Interestingly enough, there were no access events for that file until cut access permission down to just execute and set ownership to root:root. The idea was to proveke access error, and I knew the file is going to be read or written. Then the auditd threw an event of interest, so I could see what process tried to access file and the daemon's UID and GID among other info. Another method could have been using inotify command line utility, which comes with the incron package. Will try it some other time. And last, but not least, all that goodness is available from kernel 2.6 and up, you maybe out of luck if you are running an older kernel. |
