kandi X-RAY | multi-pass Summary
This is a multi-user version of Pass - the standard unix password manager ([passwordstore.org][1]). It’s a series of scripts that facilitate multi-user (even on multiple machines) access to one common password store. Each user will have his/her own password to access the store. New users can register for access by themselves, but an existing authorized user need to approve the registration before access is granted. Pass is already using GnuPG and Git, so this multi-user version simply builds on that.

QUESTION
I'm trying to run a SQL script inside an R notebook chunk. However, the final SELECT returns no results if it is preceded by multiple SQL statements (that don't generate result sets) within the same chunk.
- I have a functioning connection. The database server runs SQL Server.
- My chunks that only contain one statement return output in a dataframe.
- However, I also need to do multi-pass SQL in a script. I'd like to create temp tables along the way and use them to drive some aggregations. I want to save the results into a temp table and conclude with a single SELECT statement from the temp table, producing the output from the chunk.
- I tried saving the script to a file and using the
code
attribute for the chunk. That just got me an error about an incomplete final line. I don't require a separate file. I was just trying another way to hack this, but I couldn't make that work either.
It hasn't worked yet, and I have been unable to trace the problem. Maybe SQL chunks don't even support what I want to make them do. Any ideas?
- In an R notebook SQL chunk, is it possible to run multiple SQL statements?
- Is it possible to create a temp table and reference it in a subsequent statement within the same chunk?
- Is it possible to execute a loop construct within the SQL chunk?
Here are some toy examples.
This chunk works, returning a dataframe.

Answered 2022-Mar-01 at 13:47"Amortized constant" means "constant most of the time". push_back
will be O(1) for most of the calls. If reallocation is required, it will be linear, but this should happen relatively rarely.
If reallocation is required for insert
, all elements will be moved, that's O(n). If reallocation is not required, all the elements to the right of newly inserted elements are moved, but that's still O(n).
Cppreference doesn't seem to mention reallocation in Complexity section reliably. For example, resize()
mentions possible additional complexity in Complexity section, but push_back()
and insert()
mention reallocation only in the function description. Might be worth to clean it up one day.
QUESTION
I am rendering images on a canvas in Unity on the Hololens 2. The images (different colors) are shown in Hololens remoting or when deploying the app as expected. If I try to record these images via Mixed Reality Capture, they are not shown though. I have a control 2D sprite next to these images, which is shown. I tried both single-pass instanced rendering, multi-pass rendering, Mobile-Particle-Additive shader and Sprites/Default shader, nothing changed the problem that the images appear normally in the app but are not shown in the Mixed Reality Capture.
What are possible reasons why objects are shown normally in the app but are not shown in the mixed reality capture?
Here is an example of the components that each of the image contains:
I changed the shader as described above and and the material to Default-Sprite material, this doesn't affect the Mixed Reality Capture. The InterfAnM element is also attached to a sprite I added to the scene, which shows up, so this should also not be the reason. The frame is a 2D sprite, it had a black background, I removed that with gimp and reimported again, also didn't change anything.

QUESTION
Host machine: Debian 10 running NoMachine 7.2.3 Settings: Specified H264 User Hardware Encoding enabled Use Specific Frame Rate enabled (60FPS) Use Acceleration enabled
Client: Windows 10 running NoMachine 7.2.3
Both machines have monitors attached. Using NX protocol for connection. FullScreen / Scale to Window / Desktop is currently 2560x1440 (reduced from native while testing this issue)
Specific issue: I do a ton of work in the terminal and when viewing desktop via nomachine, the terminal caret is randomly not visible. The same issue is less noticeable with right click menus and other areas of "visual updates in small screen space." If this were another remote desktop vendor I would try to find the "don't update just regions" setting to force the entire display to update regularly, but I can't find similar settings for nomachine. I have a dedicated gigabit connection between the two machines with no other traffic on that line, so bandwidth is not an issue.
To recreate: I disabled caret blink (using universal access / accessibility settings) so the caret is a solid block in terminal / vi. If I edit a text file in vi and move up and down, the caret will only update visually every other line or so (verified on the physical screen it is moving correctly). Same if I highlight or insert, etc. You inevitably miss a character or so or lose your place).
I have tried changing speed vs quality slider, resolutions, swapping from h264 to VP8, etc. I have disabled: multi-pass display encoding frame buffering on decoding client side image post-processing
Nothing seems to change this specific issue. Yes I can make dragging a quarter-screen-sized terminal window smoother, but that doesn't help me follow the caret in vi/vim. Both machines are nicely spec'd (client has 16G / RTX2080, server has 32G / GTX1080)
Is there a way to get nomachine to update all the screen all the time, or at least better refresh small areas like a terminal caret?
...ANSWER
Answered 2021-Mar-08 at 17:11(OP): Based on a night of troubleshooting, the issue seemed to be either:
- An issue with the Debian install of the nvidia drivers
- The server machine is a laptop with a broken main screen (but with an HDMI external monitor plugged in). The Debian X-server may have been confused as to whether it was headless or not and caused issues with nomachine (which tries to detect headless and start a virtual session).
The solution to this exact problem would be to disable the GUI and force a virtual session, per https://www.nomachine.com/AR03P00973 (dummy dongles won't work because the laptop's main display is not a standard plug).
In my specific case, I needed GUI access on the server at times so I couldn't use the above methods, and I could not remedy the problem with Debian, so I wiped the system and installed Ubuntu 20.04, which is more forgiving with graphics drivers and monitors. After setting up the Ubuntu system as similarly as possible to the Debian system and letting the proprietary nvidia drivers auto install, nomachine connected at the same resolution and worked perfectly, without the lag in small screen areas.
QUESTION
I'm currently building a multi-pass compiler for a block-structured language language. I have built a scope stack in semantic analysis phase. When entering a new scope, create a new table, push it to the stack and make it current scope table, then all symbols inside this scope are inserted into current table. When leaving a scope, the current table is recorded in the AST node, then pop it from the scope stack.
This way, in code generation phase, it does not have to build the symbol table all over again. Once it enters a new scope, it can simplely get the table from AST node and then push it to scope stack. I think this is the way that most of the compiler text books have recommended.
In most cases this works just fine, however, there is a corner case I don't know how to properly deal with. Consider the following code example:
...ANSWER
Answered 2021-Mar-08 at 16:49One solution to this problem it to let the AST node for an identifier contain a link to the specific symbol found in the symbol table at the time of its creation. Under the assumption the the program text is parsed sequentially from beginning to end, one statement at the time, this will give the correct symbol. This also removes the need for doing repeated lookup in the symbol table.

I have a text-based (as opposed to table-based) .docx document with a section that has several places in the paragraph for replacement. This paragraph must be duplicated and the tokens replaced for each entry in the array. I'm continuing to comb through the documentation but am kind of stuck on this one -- most of the examples are table-based and I'm not seeing how I can accomplish what I'm shooting for.
Here's an example of the section in the .docx file I am using as a template so far:

Answered 2020-Sep-03 at 16:00When you use block=begin ... block=end
those is the syntax for absolute bounds. They indicate the position of the start and the end of the block in the source.
In a doc, you don't have access to the inner XML source. So it is advised to use the relative syntax for blocs.

Answered 2020-Jun-23 at 02:10The problem with your regex is that the second ^General
absorbs those characters and prevents them matching on the second group. Also I'm not sure what you are trying to achieve with [\s]
as that will match any space character when not matching the first part of the regex. I think what you actually want is to use a positive lookahead for General
