kandi X-RAY | coworkers Summary
[js-standard-style] Coworkers is a RabbitMQ microservice framework. Coworkers is a new microservice framework heavily inspired by [Koa] which aims to be a simple, robust, and scalable foundation for creating RabbitMQ microservices. Through leveraging generators Coworkers allows you to ditch callbacks and greatly increase error-handling. Coworkers also uses [Amqplib] a battle-tested AMQP client, under the hood to communicate with RabbitMQ and has best-practices baked in. Finally, Coworkers enables easy scalability by running each queue-consumer in its own process through node clustering (optional).

QUESTION
My coworkers showed me following example today:
...ANSWER
Answered 2021-Jun-10 at 18:31Cool. Every compiler is wrong.
Within bar
, the call to foo(value)
only has the unconstrained foo
visible in scope. So when we call foo(value)
, the only possible candidates are (1) that one (2) whatever argument-dependent lookup finds. Since T=int
in our example, and int
has no associated namespaces, (2) is an empty set. As a result, when bar(42)
calls foo(42)
, that's the foo
that is the unconstrained template, which should print 1.
On the other hand, within main
, foo(42)
has two different overloads to consider: the constrained one and the unconstrained one. The constrained one is viable, and is more constrained than the unconstrained one, so that's preferred. So from within main()
, foo(42)
should call the constrained foo(same_as auto)
which should print 2.
To summarize:
Clang gets this wrong because it apparently caches the
foo
call and that's incorrect - the otherfoo
overload isn't a specialization, it's an overload, it needs to be considered separately.gcc gets this right in that the two different
foo
calls call two differentfoo
function templates, but gets this wrong in that it mangles both the same so that we end up with a linker error. This is Itanium ABI #24.MSVC gets this wrong in that argument-dependent lookup within
bar
forfoo(value)
finds the later-declaredfoo
.
More fun is if you change the functions to be constexpr int
instead of void
, which lets you verify this behavior at compile time... as in:
QUESTION
I am adding sections to our website and all but one of them are working the way I want: i.e. no margin between sections.
I'm not able to get this one page's sections to have no margin between sections; they have extra space beneath. I have went over the code with a fine tooth comb and cannot find the error.
I am first including the code of a sample page that works correctly:
...ANSWER
Answered 2021-May-20 at 17:39What you are experiencing is called "collapsing margins". Example: If there's an h2
as the first child element inside a div, and the div has no margins, the top margin of the h2
will "go outside the div" at the top - h1, h2 etc. tags have a default margins in practically all browsers (which is a browser setting). To prevent that, you can define all margins for according elements as zero, like I did below with
QUESTION
I am trying to find a good git workflow for a specific situation.
General case works fine: I have a master branch, from which I create a feature branch. I regularly rebase feature onto master, and once feature is ready, I do a pull request on master.
...ANSWER
Answered 2021-May-19 at 07:36While you generally do not merge merge to another branch, in this particular scenario, that would be the more practical option (as in "merge master to a branch")
Rebasing a branch used by other branches gets tricky real fast, and the rebase
operation is best reserved to branches not used by other branches.
QUESTION
I have 3 Columns of data. Column E = Duration. The user will enter a number of days (Duration) for 20 employees. Column F = Pay. List of wage for each employee. Column R = Pay Total. This is a calculated field based on the number of days (Duration) and the employees pay (Pay).
To keep my employees from finding out their coworkers pay I only want to see a sum for Column C if there are at least 3 records in Column A.
I found this Sum only if 3 From that answer I tried to use =IF(COUNTIF(E2:E15,">2"),SUM(R2:R15))
What this does is only returns records with a duration of greater than 2 days. I don't care about the number of days. I want the indicator to be that there are 3 cells populated in this column.
I think the only issue with the formula is the CountIF part. I need to know what I should use to count cells not days.
In the image above you can see that it's returning a sum bc both records are greater than 2. Like I said before I don't care what number is in the cell I just want to see the sum if there are more than 2 cells populated in that column.
Thanks for any help

QUESTION
I have a series of obj files which were produced by photogrammetry by my coworkers who specialize in dealing with GIS (Geographic Information Systems) data. The first few data points in the files look something like:
...ANSWER
Answered 2021-Apr-30 at 15:44The reason for the problem with these files is the large offset combined with 32-bit float values. In this case the objects all use the same geographic origin, probably at a lat/long of 0.000N/0.000E
Nearly all 3D graphics programs use 32-bit floating point values to store each points location, and the combination of the offset and the 32-bit value causes some of the precision to be lost. 32-bit floats have about 7 decimal digits of precision, so the offset of 4460688 in the example file completely dominates, and effectively cuts the model from 1mm resolution to 1m resolution data. The reason for the long triangles is that there is more data lost in one direction due to the asymmetry of the offset.
The solution is to apply some offset to bring the objects close to the origin BEFORE importing them with the 3D software. I wrote a quick python script that can help with this: https://gitlab.umich.edu/lsa-ts-rsp/xr-shiftOBJ/-/blob/main/shiftOBJ.py
QUESTION
I’m currently leading the migration from CVS to git at work, and I would like to make it as difficult as possible to make unintentional errors for my coworkers.
If you run git rebase
and you have uncommitted changes, you get the following error:
ANSWER
Answered 2021-Apr-28 at 00:55Unfortunately, there is no trivial way to get what you'd like here. Both this form of git checkout
and the newfangled git restore
command assume that when you ask Git to overwrite $file
in your working tree from the version found in $hash
, you really mean it—even if $file
already exists in your working tree and differs from the copy in the index and/or in HEAD
.
What you can do is write your own Git command. Pick a command name that does not yet exist. (I do not know what to call this command, so I'll pick xyzzy
, one of the two magic words from Colossal Cave Adventure.) Create an executable program—in any language you like; I usually use shell scripts here—named git-xyzzy
and place it in your $PATH
. Then, when you run git xyzzy
, Git will run your command.
Your command should:
- take a
$hash
and some set of$file
arguments (you choose how to do this); - check that the given
$file
arguments either do not exist in the working tree, or are safely committed; and - run
git restore
orgit checkout
as appropriate.
That's generally a pretty short script, mostly using git rev-parse
on hash IDs and git diff
or git hash-object
to check whether the file is safely committed.
QUESTION
For one problem, we may want to solve it by 3 ways. Sometimes we can just comment out the code and try for the 3 methods, but what if we want to have 3 snapshots of working code, easy to switch in a couple of seconds? (and so that the React website can just "hot reload", such as to show the three solutions to the manager or coworkers).
I could accomplish that if I git clone
3 times, and edit each directory to however I want. In this case, we don't have to do any commit at all. The catch is that, if it is a React app, for example, we have to stop the server and restart the server in another directory. (instead of dynamic reloading of the site...)
Then is the other way, to create a branch
...ANSWER
Answered 2021-Apr-20 at 16:02Specifically,
Is it true that when using Git ... we have to ...?
Is this the only way to make it work?
Well, no. There are multiple different ways to do it, even in Git. But both of the ways you specifically asked about, are (IMHO) decent workable solutions, but perhaps could use some minor (conceptual) tweaking.
Side Note: you didn't state it explicitly, but you implied that you intend to serve your app out of a directory inside of the repo. I tend to avoid doing this. Instead, I would have the repo off to the side and use deployment scripts to move the appropriate subset of files to the served location. The benefits of this is you can pick and choose exactly which subset of files are served, and, perhaps more importantly, the served location is more likely to be clean. For example, when a Git repo is in the middle of an operation that has conflicts which require manual intervention, it is oftentimes not in a usable state. That being said, many people serve out of a repo and (AFAIK) it works for them.
As for some ideas:
- 3 different directories on the server: From a Git point of view, I would actually consider this a subset of Option #2 or #3. I don't think you need 3 separate copies of the repo; just one would suffice. But you could still have the 3 different sets of code deployed into 3 different directories on the server, each one represented by a different commit. If it's easy enough, instead of changing which directory the endpoint uses, you could set up 3 endpoints at the same time so that the audience can see all 3 without any delay (or even try each one themselves at any time).
- 3 different commits on the same branch: this is actually how many people develop code naturally: Make a new branch to work on. Try something and commit it. Tweak it or completely redo it and make another commit. (Note right here you don't have to comment out the previous try, just replace it completely since it's already saved in the previous commit.) Tweak some more and commit it. If you do this, for your demo purposes, you can either
git reset --hard [commit-id]
orgit checkout [commit-id]
to switch between the states of the specific commits you want, and deploy that to the served directory (if you aren't already serving out of the repo). - 3 different branches: note that a branch basically just points to a commit ID, so whether the 3 commits are on the same branch or different branches doesn't really matter. The main difference is if you use different branches, you get the benefit of checking out with a nice text name:
git checkout cool-feature-test1
orgit checkout cool-feature-test2
, etc. Note, you could actually do something similar even if the commits are on the same branch, by instead tagging the commit IDs with a nice name, and then just checking out the nicely named tag instead of the commit ID. I might avoid using tags though on stuff that is likely going to be thrown away at some point. If you were about to tag commits on the same branch just for this reason, then I'd instead make new branches from each of those commits, and you end up at #3 anyway.
If it were me, I'd probably combine #3 (separate branches) and #1 (multiple endpoints). I prefer #3 so I don't have to remember exactly which commit IDs to switch back to, and #1 so I could just give the testers the URLs and ask them for feedback on their own time. (#1 is also nice if deployment takes a while in a live demo, particularly if any code requires compilation.) With #3 you also get an added benefit of being able to tweak each try separately if you intend to make additional edits to more than one attempt after the demo.
Again, any of these should work just fine. I wouldn't stress out too much about which way to go. Pick something and try it, and then adjust if you find the need.

QUESTION
I'm trying to properly script importing a daily database into a master database.
Everything in the script I have currently works just fine, except for the import step.
I want to:
arrange by matching names update matching records in found set add remaining data as new records and I want to set my matching field to the UUID in my database. dialog off
I've found that when importing via script, filemaker doesn't really let you do "matching names" and set the matching field.
I've resorted to setting the script to use Last Order and manually importing a sample file before I do a batch of imports via script. Kind of a pain, and not a solid solution for me to share with my coworkers.
ANY help is appreciated!
...ANSWER
Answered 2021-Apr-14 at 05:42Select "Matching Names" option. It will match the names of both tables. Then select the UUID field option as "Match records based on this field". Now the "Matching Names" automatically changed to "Custom Order". It will still remember the field mapping.
