xubuntu – Thunar – deleted both ends after copy

Use Thunar 1.6.15 and copy large multi-gigabyte files from my main Xubuntu system to a Windows 10 share.

After the copy attempt, not only the copy failed, but it also seems to have deleted the file from both sides. The file I was trying to copy has disappeared and I can not find it anywhere.

I did a simple drag-and-drop in Thunar, so I think it was using SMB support from gvfs.

It's embarrassing but not the end of the world. I can recover the data but it will take a little time.

In the past, it seemed to me that I could copy large amounts of data if I did it one at a time. But if I drag on several large files, I have problems.

Any ideas on what happened here?

Help with a script for Google sheets so that both ends of a link can be edited

I have therefore found an excellent answer to a question regarding the connection of two different worksheets with a link that would allow you to edit one or the other and the other to update it. I found an excellent page about it, but I'm not sure how to proceed. Enforce.

var targetID = spreadsheet-id;
var targetSheetName = & # 39; Sheet1 & # 39 ;;

function onEdit (e) {
// Get the properties of the event object
var range = e.range;
value var = e.value;
// Get the position of the cell
var row = range.getRowIndex ();
var column = range.getColumnIndex ();
exportValue (row, column, value)

function exportValue (row, column, value) {
var ss = SpreadsheetApp.openById (targetID);
var s = ss.getSheetByName (targetSheetName);
var target = s.getRange (row, column);
target.setValue (value);

So, to give you a glimpse of what I see here: I understand that the first two lines are placeholders for later, the onEdit function has a variable e (I'm not quite sure what that means but I'm having trouble with it now). Then, in the next two lines, you define the range and value of the area that will be updated, and I do not know how to change the range and value, for this to work.

Then, the line is the line in which it is located, column is the column in which it is located, and then the function uses the exportValue function to paste the data into the other worksheet.

So, these bits that I do not understand are the lines 6 and 7, the parts range and value, the need for e and imagine how it works permanently.

The goal is to have a master spreadsheet and then many small spreadsheets that are just a master sheet so that specific people can see only specific pages of the master spreadsheet.

Thanks in advance

The installation of Oracle XE on Windows 10 Pro ends abruptly

I have downloaded Oracle XE 18c for 64-bit Windows and tried to install it on a Windows 10 Pro computer. I've checked the checksum SHA-256 and it's ok.

The installation starts well, but when it copies new files, it suddenly says "Cancel installation", then ends and there is no error log to view (I do not have a% folder Program Files% / Oracle with the results). Ideas?

Note: I had the same problem with Windows 10 Home, and then upgraded to Pro, but the problem persists.

dnd 5th – Swift Quiver ends earlier if you run out of arrows after being cast?

The Level 5 Ranger Charm quick quiver (PHB, pp. 279-280) says (bold italics my accentuation):

components: V, S, M (a quiver containing at least one ammunition)

You transmute your quiver so that it produces an infinite supply of non-magical ammo …

At each of your turns until the end of the spell, you can use a bonus action to perform two attacks with the help of a weapon using the quiver ammo. Whenever you do such a ranged attack, your quiver magically replaces the ammunition you used with a similar piece of non-magical ammunition.

From what I understand, the ammo is only replaced when you use it to perform these special bonus action attacks, and do not replace the ammo you use when you make regular attacks with your action .

So, let's say we have a ranger who has more than one arrow. They throw quick quiver (The quiver containing only one piece of ammunition meets the requirements for hardware components) and now this spell is active.

If this Ranger fires his last arrow with his action (that is, a "regular" attack and not one of those bonus action attacks replacing an arrow), the spell will take end because the quiver no longer contains ammo (and to my reading, the spell does not replace the ammunition used by "regular" attacks)? Or, since the material component was satisfied at casting, does not the hardware component need to remain valid for the duration of the spell after that date?

python – How to wait until an operation ends in C #

I have a C # code in which a Python code in which it is executed through CMD codes in C #. When the Python code is executed, the operations are complete, a JSON file is created, and it will be opened in C #. In this situation, how can the C # code wait to check whether the Python output (data.json) is created or not, and just when the output is created, the rest of the C # code can be executed.

latex – Are there front ends of type hackpad in github?

At work, we regularly use hackpads with LaTeX mathematics like hackmd.io for documents, but they should all eventually land on github, so it would be easier to start there.

Is there a similar solution directly supported by git or even github? You can already edit documents directly on github, but this structures them as extraction requests and does not support simultaneous editing.

We want (1) an interface similar to hackmd.io in which several people can simultaneously edit and render directly markdown containing LaTeX mathematics, although pure LaTeX may be acceptable and sometimes desirable.

We also wish (2) that the changes be made directly in git, preferably after being grouped and with some attribution to the publishers. I assume that batch processing may require changes to the present hackpad under a neutral name, but indicate the editors in the validation message.

It would be nice if the hackpad runs its own git locally, or maybe gitlab, accessible via git over ssh or whatever.

Something like that?

Airlines – The travel agent has not added MR to my name and my name ends with MS. This caused my name to be put as Ms on ticket

This will certainly not cause you any problems, and if so, they can be solved very easily by BA staff.

There is no need to add "MR", "MRS", "MS" or similar to the name on a ticket, although this sometimes happens. Versions with and without the title are completely valid.

In this case, the BA website apparently tries to analyze your name and displays it incorrectly. As long as the ticket itself contains a valid version of your name, at most can result in a few seconds delay when recording – although I suspect that even this is extremely unlikely.

Although it is less rare, the title was previously placed before the first name and often only an initial was used for the first name. My name starts with "S" and I am a man; my tickets have therefore often become NOM / MRS and more than once, I have been called "Last Name", but this has never caused any other problems than ". a minor confusion.

Dg.Differential Geometry – Finds the local coordinates of the ends of a time-varying line (two other objects) to minimize line length variance

  1. Line A 'rotates cyclically around point A' according to a time-varying pattern and coordinates of point A & # 39; are fixed (that is, line A has only one degree of freedom).
  2. The BB line can move along the x and y axes (translational motion) and can also rotate around the B point with the constraint that the distance between points A and B remains constant.
  3. The simultaneous translation and rotation of the BB line also occurs cyclically according to a fixed time variant model, the cycle time corresponding to that of A +.
  4. Due to points 1, 2 and 3 above, the angles AB & ABB vary over time and are cyclic.

Using any numerical method, can we find the X point in the local coordinates of the A line (that is, the distance AX and the angle A (AX) are fixed) and the Y point in the local coordinates of the BB line (that is, the BY distance and the BY angle are fixed) ) so that the coefficient of variation (CV) of the distance between the point X and the point Y is minimal for a given set of snapshots spaced in time over an entire cycle? We need to exclude the trivial solution: the AB line (ie the A point inside the local coordinates of the A & A line and the B point inside the local coordinates of the line BB & # 39;). Please refer to the attached image.

I'm not sure this question is qualified to be part of mathoverflow.net, so move it to another math group if moderators find it.

Why Google officially ends some old features of the search console?

Here are some of the upcoming changes in the search console that Google plans to do by the end of March 2019:

  • Exploration errors in the new index coverage report
  • Sitemaps data in the index cover
  • Use the URL inspection tool to recover as Google
  • User management is now in the settings
  • Dashboard structured data to reports dedicated by vertical
  • Release some old features

Here are the details: https://webmasters.googleblog.com/2019/01/focusing-on-new-search-console.html

Why are they doing this? How will this affect us?
