QUESTION
While replicating:
https://sortablejs.github.io/Vue.Draggable/#/nested-example
(code)
I ran into an issue related to the model; how can I add draggable to vue components instead of a raw json (as used in the example).
What I want to do is, add drag and drop to:
https://codesandbox.io/s/gg1en
(each item can be moved ("dragged") from one group to another, each group can be dragged from a lower position to an upper one (and vice-versa).
I tried:

Answered 2021-Jun-14 at 09:44If you have a component prop that's being mutated, there are multiple options:
- Convert your prop to a custom v-model. It will allow two-ways bindings without problems. (Use the prop name
value
and sent$emit('input', this.value)
to update it. - Use
prop.sync
modifier, which is kinda the same as usingv-model
but the prop has a specific name. Use:data.sync="myItems"
on the parent, and run$emit('update:data', this.data)
inside the component to update it. - Copy the prop to a data variable inside the component. So that the prop is only used as a default value for this data, but then it's only the data that's being mutated. But this won't allow the parent to see any modifications on that prop since it's not being updated directly.
QUESTION
I have the following pseudocode with the filter implementation, it works by coincidence with what the user entered in the input field.
When the user enters the word "tes"
, he sees item "test"
, if he writes "tesz"
, then he will not see items.
How can you implement the functionality that the user will allow if he typed(
entered incorrectly) in a 1 letter word, still get the desired result, because it often happens that the user misses and writes the wrong letter.
!That is, I need a filter that, if you make a typo, will still display a suitable result, how can I achieve such an effect? In this case, they are not interested in any complex calculation algorithms, but at least a typo in 1 character

QUESTION
From what I unserstand, in a FFT the number of frequency bins is exactly the number of samples / 2.
However, matplotlib.specgram gives me one bin too much.
...ANSWER
Answered 2021-Apr-14 at 17:47Just a wild guess, but if you set NFFT to 1024, it should have 1024 bins. However, if your input is real-valued, the values should be symmetrical. The 0th value should be the DC value, and the 512th value should be the value with the highest frequency. The 511th and 513th should be identical, so the spectrogram might filter out the symmetric values, as it knows the input is real-valued. So you get 513 values. (because the 513th to 1023th values are hidden; starting count at #0, of course)
The reasoning behind that is that the FFT folds a 'rotating' value on top of your data. It starts rotation slowly, #0 is the dc value, followed by #1, which is one rotation on the entire data. #2 is two rotations, and so on.
#512 is 512 rotations on your data of 1024 points, meaning you get one full rotation every 2 samples. This is the nyquist frequency for your data, everything above that will be subject to aliasing. Therefore the #513 looks identically to #511, just rotating in reverse. #1023 is identical to #1, just a single rotation, but in the opposite direction.
For complex-valued data, folding with a clockwise rotation and a counter clockwise rotation makes a difference, but for real-valued data it is the same. Therefore values #513 to #1023 can be discarded, leaving you with 513 meaningful buckets.
Another detail: Technically, the output values of the FFT are always complex, even with real-valued inputs, and contain both a magnitude and a phase information, but your library probably filters out the phase information and just gives the magnitude, to convert it back to real-valued output values.

QUESTION
I am implementing an client for a 3rd party JSON REST API. At the client side (my project) I am using Retrofit and GSON as libraries. The server side seems to implemented in PHP and is beyond my control, i.e. I cannot easily bugfix the server.
The server frequently response with varying actual types for the same formal type. Out of the box, I get a lot of GSON parsing/conversion exceptions during deserialization, because GSON is very fussy about correct types.
How do I make GSON more robust, when it comes to deserializing responses and type conversion? I already found the annotation @JsonAdapter
which probably allows me to work around those quirks of the server. But as this seems to be a typical PHP problem (examples follow below), I thought that there might already be a library or facade for GSON which solves these problems.
Specifically, the server shows the following quirks:
Boolean: Booleans in responses are reported as actual JSON boolean, i.e.
{ b : true }
and{ b : false }
, but also as JSON numbers0
and1
and as literal strings"0"
,"1"
,"true"
,"false"
. In addition, a false value is also reported asnull
(no object) and the literal string"null"
.Numbers: Numbers in responses are reported as actual JSON numbers, i.e.
{ n : 42 }
, but also as literal strings"42"
. Moreover, a zero value is also reported asnull
(no object), the literal string"null"
,false
(boolean value) or the literal string"false"
Arrays of objects: If the array is non-emtpy everything is fine. The response is
{ arr : [ ... ] }
and GSON happily deserializes this into a JavaList<>
. Empty arrays are the problem. The server reports empty arrays correctly as[]
but also asfalse
ornull
.
The list above is only the beginning of oddities I have encountered so far. Probably there are more of them. That's way I am hesitating to write may own adapters for GSON, because I fear that the list will soon become endless. Any libraries out there which already have implemented conversion for those typical PHP problems?
Luckily, the GSON converter only needs additional robustness for deserialization, i.e. if a response from the server is parsed into a Java object. When Java objects are serialized into JSON and sent to the server within a request, the server happily takes any type as long as PHP is able to convert it into the required type.
Update
I started writing custom type adapters QuirkyBoolean
, QuirkyInteger
for the plain-old Java types (int
, long
, boolean
) and their OO counter parts Integer
, Long
, etc.
That has been easy so far.
The tricky part is to implement a generic list adapter which covers the quirks which are mentioned in item 3 (see above) and can correctly deserialize any type inside the list correctly.
My problem is Java's type erasure.
Maybe someone has a solution for the following problem?
Assume the following annotated POJOs for GSON serialiation/deserialization.
...ANSWER
Answered 2021-Apr-08 at 06:07You don't need that many type adapters since you can merge the common deserialization logic into type adapters designed for each problematic literal type (just like you posted in your question) encountered from that back end.
Type adapters created independently, not in type adapter factories, usually fit simple cases. Factories provide access to the shared context Gson
instance (the one you configure and then use) and provide a concrete type to build a type adapter with (this is where "T.class" can be worked around).

. Appointments can be linked to two different Users - a student and a member of staff. The Appointment
table contains two foreign keys: StaffUsername
and ExternalID
. These reference columns in the User
table named Username
(the User
table's PK) and ExternalID
(a UNIQUE index). Here are the table definitions:

Answered 2021-Apr-07 at 19:12In EF6 an Entity only has one key, and so all Navigation Properties must use a Foreign Key that references the same key. EF Core supports Alternate Keys, and supports a Database-First workflow with Reverse Engineering.
QUESTION
I'm trying to figure out if these two queries are logically identical - from a theoretical/boolean algebra/relational calculus point of view.
I have a query with an OR
that runs poorly (i.e. a cost of 138 units):
ANSWER
Answered 2021-Mar-24 at 07:47The forms of the two queries do not have the same semantics in general -- although it might need a more complex example to demonstrate a different result.
The first form (with OR
) has SELECT ...
but not SELECT DISTINCT ...
. So it might produce duplicate rows. (See references 5, 6 at that link.)
The second form has ... UNION ...
but not ... UNION ALL ...
. So it must not produce duplicate rows, even though the individual SELECT ...
s are not DISTINCT
.
OTOH if that were the only difference with your particular schema on your particular DBMS with its particular configuration, I'd expect the UNION
(not ALL
) form to perform worse, because it needs to de-dup.
QUESTION
The following code can do Static Generation of Next.js at build time, when it is fetching data at the Home component level:
...ANSWER
Answered 2021-Mar-12 at 07:42I'm afraid it is not possible right now, if you want to have server-side data fetching then it is only possible to have it on Page Component level.
Quote:
getStaticProps
can only be exported from a page. You can’t export it from non-page files.One of the reasons for this restriction is that React needs to have all the required data before the page is rendered.
Also, you must use export async function
getStaticProps() {}
— it will not work if you addgetStaticProps
as a property of the page component.
You can also read what counts as Page Component
Maybe something will arise when React releases server components, I think React team works with NextJs team on it.
