macos – csrutil disable: command not found El Capitan

I was using a SATA hard drive running Yosemite on a 2012 MBP.
I installed an SSD with El Capitan.

I took out the optical DVD drive and replaced it with a drive housing for the hard drive.
Now, when I run the SSD, I cannot access certain folders from the hard drive. I would like to access it.

I tried the usual deactivation of SIP – csrutil disable and i get the command was not found.

What am i doing wrong?

Is the command palette a UX tool only for experienced users? Or can they be used effectively by non-technical users?

Command palette

VS Code is also accessible from the keyboard. The most important key combination to know is Ctrl + Shift + P, which brings up Command palette . From here, you have access to all the features of VS Code, including keyboard shortcuts for the most common operations.

Command palette

the Command palette gives access to many commands. You can run editor commands, open files, search for symbols, and see a quick preview of a file, all using the same interactive window. Here are a few tips:

another example of fman

The quickest way to explore fman shortcuts is via the Command palette :

Just press Ctrl + Shift + P (or Cmd + Shift + P for Mac) in fman to open it.

Now that the command palette (see above) has become a normal user interface functionality for advanced users and developers on certain applications (vscode, sublimetext, some pythonides, jupyterlab … etc.), I think in any complex program with many hidden tools / features, a palette of commands would be of great help.

A modern command palette serves 3 separate purposes as far as I can see

  • Discovery of commands / features depending on what you want to do (ex: duplicate a file? Export a tree structure? Create a time stamped zip? … etc.)
  • Discovery of shortcuts
  • Executing commands that do not have an obvious visual interface or that are deeply nested somewhere and would require a few clicks. Or for the lazy who type faster, then move the mouse and click and don't remember the shortcuts.

The way I see human memory works is by associating what is the base object of the dictionary (key, value). And our intention is also directly related to the action we want to take. Generally, in any software, a user must learn to match their intention to the learned behavior of the steps to be performed in the software to achieve their goal. (let me know if I can explain this better). I find that the command palette shortens this approach and allows for a faster learning / practice experience.

Personally, I find it easier to remember the words and actions of what I want to accomplish than the steps I need to do to get there, so often I have to search for the exact recipe on Google and execute it manually. However, a palette of commands greatly helps with this and reduces the effort required to get it right. Google has also been a big push for people to switch from structured information to searchable (?) / Searchable information. I've also always thought that the command line was great for running when you know what you want, and the user interface is great for discovery.

As far far into the future we go from learning behaviors to simply dictating what we want and letting the software figure it out, that's what all this wizarding stuff is for.

So my question is this: is it only useful for people of certain types (i.e. developers) or is it widely applicable to the general population?

MacOS has the help search function, which is similar or its action item is quite good.

If someone wanted to implement such functionality in software, what would be the guidelines for them from a UX perspective?

installation – What are the parameters for installing the oracle 11g r2 command line?

I am trying to install Oracle 11g R2 using an answer file. I like this:

./runInstaller -responseFile /home/oracle/database/response/db_install.rsp

But when I execute the command, it always opens my Windows X (I use moba Extern). How do I install Oracle 11G R2 from the command line?

Note: I want to install the software only!

virtualization – The Virsh command does not work to install the Centos 8 virtual machine on Ubuntu 18.04 via qemu / kvm

I am trying to install centos 8 on Ubuntu 18.04 as a virtual machine. I have a wireless connection. When I execute the following command:

chh2@chh2-cpu:~$ sudo virt-install  --name=chris_centos  --ram=2048  --vcpus=2  --cdrom=/var/lib/libvirt/images/CentOS-8.1.1911-x86_64-dvd1.iso --os-type=linux --os-variant=rhel7  --network network=default --graphics=spice  --disk path=/var/lib/libvirt/images/chris_centos.dsk,size=10

I get the following error message:

Starting install...
Allocating 'chris_centos.dsk'                         |  10 GB  00:00

(virt-viewer:16144): Gtk-WARNING **: 16:41:23.769: cannot open display: :0
Domain installation still in progress. You can reconnect to 
the console to complete the installation process.

I don't know why it doesn't work. I'm a bit new to this, so it would be great to get help.

linux – Shell starts in edit mode only. No prompt appears, no command can be executed

My tcsh appears in a weird way. Whether as a login shell or in a terminal, it now always starts with a simple cursor. I can type text in the terminal but that's all I can do. No prompts appear, no linked keys work, nothing.

Help with this problem?

command line – Problem on Cmd + R after following all the previous steps

I have a problem that after all the steps have been completed successfully when I reboot and enter cmd + r. In this terminol, when I write "diskutil cs list", it says "No group of Corestorage logical volumes found" plZ help me.
And it would be a big help if you make it a step by step video and share plZ

keyboard – try to set a pause / play dictation command F8

So I am what we would call ridiculously disabled. I recently liked to use the dictation feature because I only had one hand and I often had to lie on my back.

I would like to add the F8 play / pause key to the dictation command list, but unfortunately custom dictation commands don't take a single key. It seems like the solution is to create a workflow. However, when trying to automate to record the pressure of a key, I seem to have discovered that it does not recognize that key for some reason.

Just as a note, I use this play / pause feature for iTunes YouTube videos and Chrome YouTube videos at the same time. For example, I will start playing iTunes and then start the Youtube video. Since the YouTube video was the last to interact with play / pause, this affects Youtube, not iTunes. I would like to keep this functionality if possible. So, I guess if you can't just press a single key, you would have to check whether YouTube or iTunes is the last / last interaction with the active application and act accordingly.

Does anyone have a solution or a possible solution that he can think of?

Thank you

SQL Server – Why should a SET TRANSACTION command display a long time when the processor is weak?

I signed up to fix a performance problem on SQL Server 2016 Enterprise Edition on a client site and I received a trace of the SQL Profiler captured during a period of "poor" performance. One of my observations is that seemingly harmless statements like SET TRANSACTION ISOLATION record a duration in the order of a few seconds.

enter description of image here
In the image above, the StmtCompleted event signals a duration as well as a processor of 0 milliseconds but the BatchCompleted event signals a duration of 1907 ms (I have translated the profiler duration in milliseconds by dividing it by 1000). Why should there be such a drastic difference in the length of time reported by the BatchCompleted event and the StmntCompleted event? The BatchCompleted event also signals a 15 ms processor but not the StmtCompleted. Why should the simple referral of an ACK to the client require so much CPU or time? There are also other instructions that report a high duration on the BatchCompleted with almost 0 ms reported compared to the StmtCompleted event. There are sp_reset_connection events which show a CPU = 0 ms but high durations in the order of seconds. Same with BEGIN TRANS, COMMIT TRANS, SCOPE_IDENTITY etc. And to make matters worse, there are many instances of the same commands that were executed within an acceptable few milliseconds during the same period. I am unable to find an explanation. Wondering if the battery exchange community can find a plausible explanation for this. Customer swears that CPU usage and network usage as reported at the operating system level were normal, but conceded that disk usage seemed higher than # 39; habit. But most of the commands mentioned above should not be affected by disk activity.

The site unfortunately does not do continuous monitoring. They run a profiler trace whenever they sense that the SQL server is showing "slowness". Waiting statistics are also not captured and they restart the machine periodically.

I will suggest that wait statistics from the client snapshot in addition to a profiler trace. I hope that a very high expectation "ASYNC NETWORK IO" appears :). Do I need to request another type of monitoring? Any help appreciated.

Gridlines in the "Display" command which includes many graphics?

Suppose I have a "Show" command with lots of graphics in –
say, for example, 2 plots and 3 contour plots.

Is there a "neat" way to add grid lines? (where by good I mean Tidy, like
rather than cool).

(The question is above, the elaboration is below.)

I realize that I can just paste the grid in one of the plot functions, but sometimes if I change the function, it becomes confusing.

I thought epilogue would be a good way to do it, but I don't think Gridlines works in epilogue?

Or is the best option something like creating a function that does exactly what I want (for example, a function that takes what I want to "show", and the grid lines I want as inputs, and then combines them )

If this is the latter, I don't need to see a solution – it is both above my current level and more than what I need for it. # 39; s time.

I'm just curious to know if there is a simple and integrated way (other than putting the grid in one of the "Plot" commands)

Sorry for no MWE, I feel like the issue can be understood / addressed without one.
