macos – How can I restore deleted system cache in `/BuildRoot/Library/Caches`?

I cleaned disk space and deleted some caches. Seems like some of the stuff in the cache folder has been used by the Mac OS (Sierra).

Now when I try to run rsync I see the following error:

rsync: Failed to exec xclude: No such file or directory (2)
rsync error: error in IPC code (code 14) at /BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-51/rsync/pipe.c(86) (sender=2.6.9)

How can I fix the error and restore the content of the cache folder? (I don’t have Time Machine).

P.S.

If that matter, I believe the cache I deleted had different path, it didn’t something like /Library/Caches and I don’t have the /BuildRoot dir at all on my machine.

ios – iPhone 4 won’t restore

No matter what I try, it always goes into recovery mode (Connect to iTunes screen) after restoring the device. The progress bar under the Apple logo becomes full, the device reboots, then it goes back into recovery mode. Same issue when trying DFU restore. I’ve tried Finder on macOS Big Sur, iTunes on Mavericks, iTunes on Windows, and 3uTools. No dice.

restore – How to get video and audio from DVR (WFS0.4) on a camera’s SD card?

I have an almost no-name camera from the vendor viguard. Some time ago I needed to get the recorded video from the card.

The problem is that I need to get it for about 15 days, but legally I can receive video only through the proprietary 360eyes application. Everything is aggravated by the fact that I can’t just start recording for 15 days: the proprietary 360eyes interrupts the broadcast every 10-15 minutes.

It turns out that all that remains is to receive video directly from the memory card. Using X-Ways Forensics, I transferred the SD data to a binary file, and also recorded it to another SD for experiments (unfortunately, none of the experiments ended successfully). In the end, the most useful thing I got from the file is the name of the camera’s file system: WFS0.4.

I tried to read the data using DVR Examiner, but the result was very bad: video without sound and with terrible floating noise.

I realized that I would have to write a program to read viguard’s WFS0.4 myself.

Does WFS0.4 have some specification (I couldn’t find any specification)? For example, what format the video (images) is stored in, how it is compressed, how audio is stored, and so on. All I found were bits and pieces. Maybe someone with experience?

I can’t figure out if this is a military secret or something. Well, there is almost nothing about WFS. Where did this come from? When? Who came up with the name and what does it mean?

mysql – why does mysqldump restore to a smaller size?

I am using MySQL and mysqldump v8.0.19 on Windows 10. I have an InnoDB database, old. I use mysqldump (and the --no-create-db option) to dump its tables. I then create a new database, new, and import the dumped tables with

mysql -u myName -p new < old.sql

This procedure seems to work in the sense that the tables in old and new seem to have exactly the same data and exactly the same keys. CHECK TABLE reveals no problems with the tables in new, and commands like SELECT * FROM old.table1 UNION SELECT * FROM new.table1 reveal no discrepancies between the old and new tables.

But for all of that, the new tables are smaller. Specifically, this command shows that they’re smaller in both data_length and index_length:

SELECT concat( table_schema, '.', table_name ) table_name,
  concat( round( data_length / ( 1024 *1024 ) , 2 ) , 'M' ) data_length,
  concat( round( index_length / ( 1024 *1024 ) , 2 ) , 'M' ) index_length, 
  concat( round( round( data_length + index_length ) / ( 1024 *1024 ) , 2 ) , 'M' ) total_size
  FROM information_schema.TABLES
  ORDER BY ( data_length + index_length ) DESC;

Why are the restored tables smaller (and should I be concerned)?

A (https://stackoverflow.com/questions/24707770/mysql-database-dump-restores-to-smaller-size)(question like this) was asked six years ago on Stack Overflow, but it never got any replies.

recovery – How to restore a MySQL InnoDB with ONLY .ibd files?

I had a Bitnami Joomla! stack running on a computer that suddenly kicked the bucket. I had neglected to make a back-up before this happened so I do not have any dumps or backed up files, but was able to save the directory and everything in it when I recovered its hard drive. I was a fool and wiped the recovered drive after removing the files I wanted to keep, so I can’t go back to get anything else….

I’ve been trying to recover the tables (76 in total) into a live MySQL installation to get access to them, create a back up and import them into a fresh stack to restore my site. I have saved every .ibd in the database’s folder, along with ib_logfile0, ib_logfile1, ibdata1, mysql.ibd, binlog.index, etc. My installation never had a .frm file that so many posts mention having, and it never did even when it was live. I do not know the tables’ structures in order to replace them one by one, and Joomla’s documentation on them is apparently outdated.

My installation used MySQL 8.0.21, running under Windows 10. I would really appreciate help to solve this issue. I’ve looked for tutorials on how to fix my issues, but they were either for prior versions of MySQL (which I am unfamiliar with compatibility) or required a back-up or that .frm file (which I don’t have). Additionally, I compared my saved directory with a fresh install of the same stack installer 3.9.22-0, and the base install did not have a .frm file from what I remember. I tried importing the raw .ibd files through phpMyAdmin and had no luck there either.

I can offer more details if necessary. Thank you for any help you can offer me!

  1. I traded the iPhone 6s and bought iPhone 12 Pro Max

  2. before trading I took backup of all my data on iCloud , then reset it and traded.

  3. Now when I started the new iPhone 12 Pro Max, I got an option under App & Data to restore data from iCloud

  4. I successfully signed in but later it is showing No Backups Available however, I could see the data on iCloud too by log in into browser.

  5. I did not take backup using iTune hence could not restore it from my PC.
