Problem knitting cv templates in the R package vitae

Asked 2021-May-04 at 02:32

When I knit any of the CV templates in the R package vitae I get a slightly different error for each one. I've made sure that all the files, including my Rmd file, are in the same directory and I haven't changed the template in any way. When I knit the modern CV template, for example, I get this error message:

A combination of reinstalling R Studio after uninstalling MikTex, and finally installing the R package tinytex worked.

I think @samcarter_is_at_topanswers.xyz was right that "the problem was an outdated latex version. utf8 became the default encoding some time ago, but if your tex version was older then such special characters would cause problems. "

Lessons learned:

The tinytex package is all you need for R Markdown. You can even open tex files in R Studio to edit and compile them to pdf. See how to install it here.
Update MikTex frequently. I assumed that it automatically updated when needed, but that seems not to be true. Windows > MikTex > Update. It's that simple. Remembering to do it is another thing if you decide to use it.
Being able to check that the environment paths are all there and are pointing to the right directory didn't help in this case, but it was good to learn. This link was helpful.

QUESTION

Will Firebase firestore offline persistence work with offline electron js application?

Asked 2021-Apr-25 at 11:10

I am working with electron js and angular. And I want to use firestore database.

As far as I know, firestore is enabled with auto persistency.

First of all, will it work with my desktop application (node base / electron + angular)?

Second, let's say my application mostly works offline. And I need to do certain CRUD operations during these uncertain offline runtimes. So, if the first question's answer is yes, can I perform above operations in offline mode and will it sync as soon as the system goes online?

Third and last, if the answer to the second question is yes, then what if my system shutdowns that is desktop?

I will be glad for a detailed explanation of answers and a detailed explanation of how persistence works and is provided.

I am new to this channel. Please don't mind if I ask my question informally.

Firebase saves all offline actions to essentially an internal transaction pool for offline persistence. When Firebase does connect back online, it will attempt to sync all previous changes including transactions, document updates, and deletes.

The issue is the local pool wasn't made for extended offline use and over time, depending on how much data, it can slow the app down to handle all the data. I've heard it should behave fine if the device is offline for about a month or two for general use but it might be better to support your offline app with an offline-first database such as PouchDB or NeDB and sync changes with Firebase as needed.

ANSWER

Answered 2021-Apr-23 at 22:44

You can introduce a concrete representation with the theorem int.abs_induct. However, you almost never want to do that manually.

The general method of proving statements about quotients is to first state an equivalent theorem about the underlying relation, and then use the transfer tool. It would've helped if your example wasn't automatically discharged by automation... in fact, let's create our own little int type so that it isn't:

check if HashMap / Map contains a class variable in Java

Asked 2021-Apr-16 at 12:03

I'd like to start clarifying that I'm new to java so I also don't know exactly how to ask this (I also couldn't find any solutions here).

Okay so I've got this HashMap where I store a class for each key, and I need to check if a variable from that class in the HashMap is equal to x.

Informal example:

this is the HashMap content:

{1: myClass("albert", "smith", 48), 2: myClass("jason", "small", 50)}

I need to know if "smith" is in that HashMap so that I can then compare it to x.

Thanks.

The difference here is in simple_filter. In your original code, you build up simple_filter as a combination of the four column filters. In your second code, you create simple_filter anew in each call, and although you return it, you then throw it away. I believe the changes you need are small:

Newbie, XSLT Transformation from XML to XML

...

ANSWER

Answered 2021-Mar-26 at 22:54

You need to group name elements by last.

Since you're using XSLT 1.0 you'd need to use the Muenchian Method.

This means creating a key (matching name and using last).

Then you need to iterate over each of the first name elements that contain the matching key (this is the part of Muenchian grouping that you can either use generate-id() or count()).

By using the value of last you can create the Crockett and Baseball elements.

Then iterate over all of the name elements in the matching key. These all become the candidate elements.

All that's left is to process the first elements (don't process last), strip the type attribute of the first elements, and change the first elements to last when the type attribute equals "informal".

Give it a shot yourself, but here's an example just in case you get stuck...

QUESTION

Formally speaking: why you cannot write a stream-reverse function for a Racket stream just like you can write one for lists?

Asked 2021-Mar-23 at 01:19

Racket provides a built-in function to reverse lists which is called reverse. This function uses the fact that lists (at least proper lists) have an end which is null (empty list).

On the other hand, streams by definition do not have an end. Actually, streams is a data structure created exactly to model infinite data.

Hence, there is not such a way to build a stream-reverse function.

Is the argumentation above enough to answer the question? Did I miss something?

It looks too informal for me.

Thanks in advance.

ANSWER

Answered 2021-Mar-23 at 01:19

While you can make infinite streams not all streams need to be infinite. Eg. (stream 1 2 3 4) will make a stream with delayed execution of the 4 elements and it is reversible.

You can make a stream-reverse, but it will not work for infinite lists just like reverse and sort doesn't work for circular lists, just proper lists.

Getting a "this field leaks a context object" when passing a context from Main Activity to Java Class via Constructor

The Code private var mService: RecordService? = null show a warning "This field leaks a context object" ? why?

I think that HomeViewModel object will be destroyed after Activity object destroyed, and the mService will be released too, why does Android Studio display "This field leaks a context object" ?

ANSWER

Answered 2021-Mar-16 at 03:48

From the Official docs:

A ViewModel must never reference a view, Lifecycle, or any class that may hold a reference to the activity context.

Since the services have their own lifecycle and are managed by Operating Systems, you shouldn't keep its reference inside the ViewModel.

During configuration change, the ViewModel is preserved, so still may have reference to Service and will cause the memory leak.

Computing Histogram of an gray scale Image

I am asked to create a function below to calculate histogram of any gray-scale image. I did quite a lot research and get together this code below. It is working well. However, I did not understand the logic behind this code exactly. To be more specific;

What kind of a array I created with histogram = np.zeros([256], np.int32) line? What does np.int32 do exactly?
In the for loop below I sort of understand but I am not feeling well understood about the way it works, clear explanation how this loop works would be a big help.

QUESTION

Is a local variable an lvalue when deducing its type using decltype?

Asked 2021-Feb-16 at 21:31

I am reading the Wikipedia entry about decltype, and I can't understand the following passage:

Similarly to the sizeof operator, the operand of decltype is unevaluated.[11] Informally, the type returned by decltype(e) is deduced as follows:[2]

If the expression e refers to a variable in local or namespace scope, a static member variable or a function parameter, then the result is that variable's or parameter's declared type

Otherwise, if e is an lvalue, decltype(e) is T&, where T is the type of e; if e is an xvalue, the result is T&&; otherwise, e is a prvalue and the result is T.

it first says: "If the expression e refers to a variable in local or namespace scope", then it follows by "Otherwise, if e is an lvalue". For me it implies that a variable from local scope is not an lvalue. Am I right? - I always thought local variables are lvalues.

Maybe item 2 refers to case where we use decltype((e)) - with double parentheses? I suppose this is what is said later in this wiki: "More formally, Rule 1 applies to unparenthesized id-expressions and class member access expressions."

...

ANSWER

Answered 2021-Feb-16 at 21:25

For me it implies that variable from local scope is not an lvalue

No, that's not the correct way to read it. The list is not a bunch of mutually exclusive options. Some properties may overlap. When determining the type decltype produces, we are meant to apply the first item whose condition is satisfied. Think of it like an algorithm, a program to determine how decltype should behave (and since the standard is a technical specification, it pretty much is that).
