shield | Hash verification | Firewall library

I need to mark a TBitBtn (not TButton), that the button action requires elevation. I set ElevationRequired to True, but I do not get the shield icon.

To reproduce, place a TButton and a TBitBtn on a form:

Apologies for asking a fairly common question, I have been looking all over and can't find a solution that fixes my problem.

I am using Firesharp, and trying to deserialize a Json object that Firebase returns into a class with a nested list.

I have function, which recieves coeffecents of polynomial via istream input. Im struggling with implementing this piece of code into it (can't fully understand how istream& works), so i can shield it from incorrect input. :

I made a help command and when i execute the command once then it works but after that it stops working meaning i have to re run the whole code. (btw this is a cog) The error that i get if i do the command more than once is Ignoring exception in command None: discord.ext.commands.errors.CommandNotFound: Command "help" is not found

My company has 2 AWS accounts. On the first (lets call it playground), I have full administrative permissions. On the second (lets call it production) I have limited IAM permissions

I enabled AWS Config (using the terraform file on the appendix) on both accounts.

• On the playground it runs smoothly, everything is fine.
• One the production, it fails. More specifically, it fails to detect the account's resources with the message "Your resources are being discovered" as shown in the screenshot below.

I initially suspected this could be an IAM role permission issue.

e.g running

aws configservice list-discovered-resources --resource-type AWS::EC2::SecurityGroup --profile playground gives me a list of the SecurityGroups discovered by the AWS Config on the playground (pretty much what I see on the console dashboard).

On the other hand:

aws configservice list-discovered-resources --resource-type AWS::EC2::SecurityGroup --profile production returns a null list (there are security groups though. Same results with other types such as AWS::EC2::Instance)

Here's the doc for AWS LB.

Here's the code sample I came up with, let's imagine I've got this LB:

Having made a program which streams PNG images to the browser by means of a multipart/x-mixed-replace Content-Type header, I noticed that only the frame before-last is displayed in the tag, as opposed to the most recently sent one.

This behaviour is very annoying, as I'm only sending updates when the image changes to save on bandwidth, which means that the wrong frame will be on screen while I'm waiting for it to update.

Specifically, I am using Brave Browser (based on chromium), but as I have tried with both "shields" up and down, I assume this problem occurs also in other chromium-based browsers at least.

Searching for the problem yields only one relevant result (and many non-relevant ones) which is this HowToForge thread, with no replies. Likewise, I also thought the issue is to do with buffering, but I made sure to flush the buffer to no avail, much alike to the user in the thread. The user does report that it works on one of their servers though and not the other, which then lead me to believe that it may be to do with a specific HTTP header or something along those lines. My first guess was Content-Length because the browser can tell when the image is complete from that, but it didn't seem to have any effect.

So essentially, my question is: Is there a way to tell the browser to show the most recent multipart/x-mixed-replace and not the one before? And, if this isn't standard behaviour, what could the cause be?

And of course, here's the relevant source code, though I imagine this is more of a general HTTP question than one to do with the code:

I'm trying to open BlueJean after a link in my browser. I get prompted if I wanted to let xdg-open open an application for the url, I agree and click the button. However, the right app is not opened and a default app opens up doing nothing. Basically, a new window is opened for my browser as the the link passed is basically an url.

The error shown on console is

I need to reduce the memory required by the KeDei TFT library used with the Osoyoo 3.5" TFT touch screen display shield for Arduino Uno and ATmega 2560. When I try writing a simple Arduino application that uses the TFT display with the KeDei library, most of the available memory on the Arduino is taken up by the library itself.

Unfortunately I have discovered that while an ATmega 2560 does have the necessary amount of memory, the KeDei TFT library does not provide correct touch coordinates when the TFT display is used with that device so the ATmega 2560 is not feasible unless Osoyoo customer support comes though with a solution.

Investigating the library source code, I found in the file KeDei_font.cpp a bitmap font table being used to generate the characters displayed. This bitmap font table is an array, unsigned char font16_B[96][16] and appears to be the main memory hog. This array contains bitmap fonts for the ASCII characters from the space character, 0x20, to the tilde character, 0x7e.

One thing that I have done is to reduce the number of characters by eliminating the lower case letters and transforming lower case letters to upper case. This results in a table const unsigned char font16_B[59][16] which is a bit more than half the size of the original table.

With this approach I also eliminate a few other punctuation type characters but as long as I'm displaying only alphanumeric characters and spaces, this will work.
