Upgrading to latest Exchange CU vs Applying “Secuirty Updates” for currently installed Exchange CU

Hypothetical: a company has Exchange 20xx installed with CU8. They are skiddish about applying CUs, but will apply monthly updates and “Security Updates for CU8”.

By doing this, are they missing critical security patches upstream in more current CUs (CU9-CU11)?

Retrieve latest files from a directory using UUID or incrementing integer approach

I have a download button in the UI, user clicks on it and download 3 files in a zip format.

It’s not necessary that the files are already there(on the server) when download button is clicked because the backend process can take sometime(30mins to 1 hr) to put the files at a particular location on the server.

Files are going to be in following format in a particular user specific directory.

file1.csv file2.csv  file3.csv 

I am planning to disable the Download button until the files are uploaded to the particular directory on the server by the backend process.

My goal is to get the latest files from the location for a particular user. In order to get the latest file I was thinking about following approaches :

1) Generate a UUID/OR an incrementing integer in the UI using Javascript. Send this UUID to the webservice which is responsible for uploading the file to the server. The file will look like this

file1_UUID.csv file2_UUID.csv file3_UUID.csv 

As soon as Download button is clicked, I am also planning to store the UUID or incrementing integer and username in a database table so that from the UI, using Javascript, I can keep on checking regularly using a webservice whether file corresponding to the latest UUID/incrementing integer exists on the server or not.

2) Generate UUID/OR Incrementing integer on the back end side (Java webservice side) and then keep on checking regularly using a webservice whether file corresponding to the latest UUID/incrementing integer exists on the server or not.

Questions:

1) Is creating a table and storing UUID , username etc in a table a good approach?

2) OR Is generating UUID/Incrementing integer on the webservice a better option rather than generating it on UI side?

3) Should I really use UUID or an incrementing integer is fine?

Please let me know if I can answer more questions. thanks !

How do the sleep sensors in latest Mac laptops work?

On older Mac laptops, placing a magnet near the steep sensors sleeps the Mac. However, on newer Macs, putting magnets on the sleep sensors won’t sleep Mac Mac, such as closing the lid does. How do sleep sensors work then? I did many tests with different laptops (12″, 13″ 2016/2017) etc, I know where the sensors are, but they won’t sleep the Mac, not even putting a magnet on each sensor.

Accessing latest files based on timestamp [on hold]

I have a download button in the UI, user clicks on it and download 3 files in a zip format.

It’s not necessary that the files are arleady there when download button is clicked because the backend process can take sometime to put the files at a particular location on the server.

Files are going to be in following format

file1_1555077233.csv file2_1555077233.csv  file3_1555077233.csv 

So that each time a user clicks on the button, I can get the latest file based on the timestamp.

I am trying to figure out where exactly I should generate this timestamp?This timestamp is going to be included with the file name at the time of file generation.

1) Should I generate it using javascript and send it along with the webservice call which is responsible to start the back end process and put the files somewhere on the server?

The problem with this approach is that how would I know the timestamp value if a user shuts down his computer and come back later looking for files after clicking the download button ?

OR

2) Should I have my back end java based webservice generate the timestamp as soon as it’s called from the UI?

The problem with this approach is that I will need access to this timestamp on the UI side so that when a user clicks on the download button, I can make a request based on the file name and let the user know whether the file exists or not. One approach is to get this timestamp from the Java webservice in json response but this would only work when the user keeps the browser open for long time which is not ideal. Let’s say user shuts down everything and come back later. How should I handle this thing ?

If there’s any additional thing I would need to do(which I think I would have to) in addition to handling timestamp generation, please let me know. Thanks

My front end is just using HTML,CSS,Javascript and backend is using springboot java webservices.Let me know if I can answer more questions.

Clarification on what I am looking for:

Meaning of the phrase so that UI is aware of the file name it's going to provide the user. from my comment.

Let’s say UI makes an Ajax call to a Java webservice. UI sends some parameters in the POST request which starts a stored procedure on the back end. I generate a timestamp in milliseconds on the Java side. When it comes to generating CSV file on the Java side, I would generate it like this :

file1_156788898.csv  

This file will exist somewhere on the server.

Now, on the UI side, I would need to know this number 156788898 (timestamp in milliseconds), then only, I would be able to get this file from the location. I am trying to uniquely identify the file which got generated recently and tied to that particular user.

One solution I could think of is:

Let’s say if , after generating timestamp on the Java side, I send it back to the browser as a JSON response. I can store it in HTML5 storage as localStorage or sessionStorage but if a user shuts down his/her computer and then decide to come back, how do I figure out the latest files associated with a particular user? Since, I won’t be having way of tracking this number 156788898 because the HTML Storage would be wiped out after computer restart. Not sure if HTML5 storage is a good way to go about it or not.

Click Gap Signal- Facebook’s Groundbreaking Latest Algorithm Update

Hello Dear,

It's been a long time I was out from this lovely community. I learned a lot here and have contributed back.

On 11th April 2019, Facebook has informed the world about their new Click Gap Signal and this news is definitely a disrupting change for Facebook eco-system.

This new Click Gap Signal has something to do with the method once used Google's PageRank (PR).

The more explanation is given by me in this video

Making the default “Latest Posts” WordPress Widget Show Thumbnails

I’m teaching myself how to build my own themes on WordPress. I’m using the latest version, and using the underscores starter theme. My question is, how can I make the default “Latest Posts” widget show post thumbnails too?

I’m trying to create a tube site style “latest uploads” page – without using plugins since they have too many features that I don’t need and I don’t want to bloat my website with unnecessary code. I’ve been trying to edit the core code for 2 days but no luck so far. All help is appreciated. Thanks!

How to get latest version of Google Play Store

I’m trying to solve a problem I’m having with Google Play Store. (Specifically, a continual “Error checking for updates” and an empty “Installed” list. I tried clearing the cache.)

The version I have of Play Store is 14.2.58, and I know it’s not the latest. I’ve read that sometimes the app doesn’t update automatically. But where do you go to upgrade the app manually?

When I google for it, I see a lot of third-party sites that offer the latest download, but I don’t know if they can be trusted. If Google itself offers the download, I can’t find it.
