QUESTION
I have an assignment which I am required to make a website using html,css,and bootstrap. I am almost done in finishing the webpage but I am stuck in resizing the lightbox
photo gallery. I want it to resize according to the screen size. Smaller screen = Smaller images. I tried setting the max-height and max-width of the images to 100% but it did not work.
Website: http://syphym.infinityfreeapp.com/TheOfficialPodcast.html
I want it to instead of making it 4 to 2 and 2 to 1 I want to resize it and maintain its original position
Sorry for the question but I really don't know how to fix this
code:
...ANSWER
Answered 2020-Sep-12 at 06:17When you use bootstrap with col
s you should know that the page width is divided to 12.
for example, if you have 4 div
s and each of them has col-3
it will place them in the same line.
But if you are trying to put 4 times col-6
in the same row, that would be a mistake (As you did, using col-md-6
)
For what you asked, I would suggest changing the class to col-3
instead of col-md-6 col-lg-3
for each of the 4 div
s
Good luck :)
QUESTION
I discovered, in this little example below, if I call pthread_create in the constructor of my struct, I get a segfault randomly on the call to pthread_mutex_lock().
And sometimes the name field is empty for the first philosopher.
If I move pthread_create to a run() function after the constructor, no segfault.
It seems the call to pthread_create happens before all the members are initialized. Shouldn't the member init list of the class be completed before the call to constructor body?
Thanks for any tips!

resizes when the code does philosophers.emplace_back()
, which can move the elements in memory, so that their previous addresses become invalid and the feed()
function ends up accessing objects using their old invalid addresses.
A fix would be to make the philosopher
class non-copyable and non-movable, and then use std::list
or std::forward_list
instead of std::vector
. std::list
and std::forward_list
do not move elements in memory and hence are capable of storing non-copyable and non-moveable objects.
You may also like to use std::thread
instead of pthread_t
, and std::mutex
instead of pthread_mutex_t
. The std
classes are non-copyable/movable which would prevent you from making this error at compile-time. Also, the code doesn't check return values of the pthread functions for errors, whereas std::thread
and std::mutex
do that for you.
QUESTION
In CRM we have a projects list and there are associated files with these projects on our network drive. Didn't want to setup Sharepoint due issues we have had with it in the past.
Anyway, in each of these project records we want to add the network URI for that project's files so the user can click on the link from the CRM record and be brought to that direct. So something like X:\Projects\contoso
.
Came across this suggestion for accomplishing this:

Basically consists of making an HTML page and inserting it as a web resource on the form, which makes it an iframe.
...ANSWER
Answered 2019-Apr-24 at 02:11Working with UNC resources is contrary to the nature of cross-browser web platform such as Dynamics 365. Along with the kludgy experience for Windows users, which apparently isn't working anyway, consider the experience for Mac and mobile users when they try to open a UNC path in their browser.
SharePoint would be the obvious choice, but with that off the table, you might want to look into implementing WebDAV on the server that's hosting the files.
These days I doubt that many would consider WebDAV to be a "modern" or popular solution for D365 file integration.
Outside of SharePoint, Azure Blob storage is a viable and popular cloud-based option.

I made a operator overloading function in a class. And I made another function which recalls the overloading function in the class.
I want to use the function which recalls the operation overloading function in main function so I wrote like this in the main function :

Answered 2017-May-13 at 05:29What you have overloaded is the pre-increment operator.
What you are using is the post-increment operator.
You can either use the pre-increment operator:
QUESTION
I've started playing around with Kotlin, but I sense my own limitation in the way I program. My problem is that I still think Java therefore the style is still imperative, my question is to all functional programming zealots , which I believe would be very useful to all people who at the very beginning stage and also need to 'brake' their brain to start building it again; to leave comfort zone and start thinking pseudo and not in "whatever is your first language". I believe it is possible for highly experienced polyglot developers to chew the concepts down to plain advices of what makes your program being written in entirely functional way and what violates the paradigm. I don't know all the quirks but please don't hesitate to include universally accepted terms which might be unknown to me(I can always lookup). At this point I need this set of rules to make myself suffer at first and not break them but then I know I will feel it, analyze guidelines and understand how they are worse/better which of course is my own homework.
So example of these guidelines, would be something like:
- Never change state, this can be avoided by using x, y, z
- Operate using higher order functions only (I maybe wrong, just example)
I hope the answer will give me long term reference to put myself in extreme conditions where I stop escaping to OOP whenever I feel uncomfortable. And now when I look at Kotlin I understand how I've should've been thinking about problems, it is about intention not about the structure imposed by one language or another. Intention can always be converted to a language of your choice and backed up by design patterns applicable to the language, but to find that middle ground I need to jail myself first from the comfort zone.
...ANSWER
Answered 2017-Apr-06 at 19:34Avoid mutable state like the plague.
One of the main points of using functional programming, possibly the main one, is to avoid all the little pitfalls, bugs, issues one needs to deal with when using mutable state. You should do everything you can in order to avoid mutating state. For instance, instead of using C-style
for
-loops where you need to keep a counter variable updated, usemap
and other higher-order functions in order to abstract away your iteration patterns. This also means that you should never change the value of a variable if you can avoid that. Instead, you should be defining almost all of your variables, preferrably all of them, as constants, and using functions to compute new values from them instead of mutating them.Avoid side-effects like the plague.
Mutable state's ugly cousin, side-effects. Side effects mean anything other than taking a value and returning a value in a function. If that function prints data, mutates global variables, sends messages to threads, or anything, anything other than simply taking its parameters, computing a value from them, and returning a value, that function has side-effects. Side-effects are important (see next bullet point), but if you use them a lot, they get impossible to track. Just think of how everyone tells you to avoid global variables in imperative programming. Functional programming goes a step further and tries to avoid all side-effects. The bulk of your program should be made of pure functions. (See ahead)
When you need to use side-effects, keep them contained.
Yes, I just told you to run away from side-effects. However, no program is useful without side-effects of some kind. Graphical User Interface? Side-effect. Audio output? Side-effect. Printing to a shell? Side-effect. So you can't really get rid of side-effects if you want to build useful stuff. What you should do instead is write your code so that all your side-effecting code lives in a thin layer which mostly calls pure functions and then does the required side-effects using the result of these pure function calls.
Use pure functions for everything you can.
This is sort of the flipside of the previous point. A pure function is a function which has no side-effects and does not mutate anything. It can only take in parameters and return a value. You should use these a lot. For instance, instead of doing your logging within functions which are computing stuff, you should be constructing your log strings using pure functions, and then letting your side-effects layer call these pure functions, call more pure functions in order to format the log strings into a full log, and then output the log itself from your side-effects layer.
Use higher-order functions to structure your code.
Higher-order functions are, in a way, the glue that makes functional programming work. A higher-order function is a function which takes one or more functions as parameters and/or returns a function. The power of higher-order functions is that they can encapsulate many of the patterns which you would use in an imperative-style program in a declarative manner. For instance, let's take a look at the three most common higher-order functions:
map
is a function which takes a function and a list of values, applies its function argument to each of those values, and returns a new list with the results.map
encapsulates the whole pattern of iterating over a list doing an operation on each value in a declarative manner.filter
is a function which takes a function which returns a boolean and a list of values, applies its function argument to each of those values and returns a list containing only those values for which its function argument returnstrue
. It encapsulates the whole pattern of selecting results from a list in a declarative manner.reduce
, also known asfold
, takes an initial value, a binary function and a list of values. It uses its function argument to combine the initial value with the first value of the list, then combines the result with the next value of the list and keeps on doing this until it has reduced the list to just one single value. It encapsulates the entire pattern of obtaining an aggregate value from a list of values.This is in no way an exhaustive list of higher-order functions, but these three are the most common ones. I hope this has been enough to show how you can structure code which would require a lot of tracking variables using only functions in a declarative manner. If you use these higher-order functions well, it's likely you won't ever need a
for
orwhile
loop again.
This is definitely not an exhaustive list of functional programming practices, but I think most functional programmers would agree these five guidelines form the core of what functional programming is about. If you want to really learn how to apply these, my advice would be to learn a pure functional programming language such as Haskell, so you are forced to abandon the imperative paradigm and to learn how to structure things functionally instead. I would recommend the fantastic Haskell Programming from First Principles as a starting resource if you choose to go this way. In case you don't want to/can't put down the cash, Brent Yorgey's Haskell course at UPenn is also a great free resource.
