Copilot in Excel just got a major upgrade by Usama Jawad It's no secret that Microsoft is trying to get as many people to use Copilot as possible. This is being done through various means, including integration with OneNote, Defender, Windows, and more. Microsoft Excel is the most popular spreadsheet software out there, so it makes sense that the Redmond tech firm would integrate and build upon the capabilities of Copilot in this tool too. Now, the company has implemented a major upgrade in this integration. In a blog post, Microsoft has made Copilot smarter in terms of context awareness in Excel. This makes the AI assistant more useful when asking questions about your data in nautral language queries. Previously, Copilot would only make inferences based on the cell that you have selected, and it typically worked quite well in this scenario. However, Microsoft has realized that workbooks and sheets have become more complex, which means that Copilot needs to be smarter too. This means that you no longer need to select relevant data when asking queries about it, you can simply ask questions such as "Show me insights about the data I was just analyzing" and "Sort the table in the top-right", and Copilot should just work. Microsoft says that this major upgrade in Copilot is due to combining cell signals with chat history in order to make inferences. It also supports data ranges, which means that it can serve as the foundation for even broader context in future updates. In order to get customers to trust the inferences that Copilot is making, Microsoft will highlight the data that the AI assistant is using. This enables customers to further refine the dataset that Copilot is using so that they can get the most accurate responses. Smart context awareness is available on the web and the following versions of desktop: Windows: Version 2505 (Build 18623.20058) Mac: Version 16.95 (Build 2506.3090) Meanwhile, the visual highlighting feature is also available on the web and the desktop versions mentioned below: Windows: Version 2505 (Build 18705.20000) Mac: Version 16.96 (Build 2506.4070) Microsoft has requested customers to provide feedback through the thumbs up/down icons present at the bottom of the Copilot response cards. -

We should probably just focus on how nice it is that finally another company is taking reusable rockets seriously. I can't believe there are so few players and many rockets in service today are still completely expendable. Hopefully Honda can scale up theirs and add some badly needed competition. I want to see planes become irrelevant for global travel and we use rockets instead. -

Yea. It's obviously being deprecated, in case no one noticed or forgot all the announcements and changes. Not such a big deal. -

The best thing would be to just allow more options to let users pick the layout they like, it doesn't matter at this point really and it's not that hard to do as evidenced but all the 3rd party menus/tools that let you change it in lots of different ways. If you give the users more options they'll be happy, take them away and you have a problem.

Question

In my latest PHP script I decided to use compression for the output, one of the reasons is that I'm using lots of JavaScript and all that code compress looks sweet. I don't have any concrete question but I need someone that already knows about the subject to enlighten me a bit on the best way to compress the output via PHP.
For instance, at first sight, I decided to go with the method I though it was best. Use an .htaccess file with the following:
This way, all the output via PHP file would be compress and this would work for everything I'm doing, including JavaScript and CSS. Anyway, this method brings some issues to the table:
1) I just tested my script on a remote server and it didn't work. It was a free PHP5 server and something tells me that the webhost has PHP ini settings modifications through .htaccess blocked. And there are many servers like this one...
2) I would like to avoid the use of .htaccess. For instance, what if someone is using ISS, this will certainly not work for them.
Another option would be to use the ini_set() function to set the PHP configuration but in all the tests I did, something didn't work and I don't understand why. All my scripts aggregate all the content to be outputed to the browser in a single variable and then I simply "echo" that variable. I tried to use ini_set to set "zlib.output_compression" to "On" and also "zlib.output_compression_level" to "9", right before echoing the content variable. But something didn't work. Maybe the syntax for ini_set() was incorrect? I mean, the dots to separate the ini setting or the underscores or double-quotes or even case sensitivity is in place? I don't know if ini_set() is sensible to all this things. Anyway, this would have been the best option for every browser, OS and server, as long as the zlib module was enabled of course.
I also found another way to do it, using the ob_start("ob_gzhandler") function, but:
1) I saw lots of code examples and I don't really know the best way to use it. I mean, I was able to use it bu, it add several lines of code that I didn't really understand what were they for and if the were really necessary. I tried to comment them and the script worked anyways with output compression but I don't really know if thoses lines would be important in the future.
2) From the PHP official documentation, they say: "Note: You cannot use both ob_gzhandler() and zlib.output_compression. Also note that using zlib.output_compression is preferred over ob_gzhandler().". And that's the reason that I would prefer to use zlib.output_compression instead of ob_gzhandler. But I would also like to understand why they recommend zlib instead of ob_gzhandler.
Now, the idea is to compress all the output done by PHP, all CSS and JavaScript files. The PHP output is very simple, all the pages in my script are accessed through index.php and by the query arguments, it will decide which page to show and then, only an echo is required to show that page. For the CSS and JavaScript, I opted to create 2 different PHP files, named scripts.php and styles.php. Both do the same exact thing. In the case of scripts.php, it will gather all the content from various .js files and output all of them. In the styles.php, the same thing is done, with the different that only one .css file is read to be outputted; but if some day I have more than one .css file (for instance, for beowser compatbility), I will gather them all in the same way I'm doing for JAvaScript. The Content-Type is correctly defined using the header() function before the output is done in both files.
Recently, a friend of mine suggested the following code:
And I want to know if there is any issue that one might not know about outputting code using this gzencode() method and that specific header. Would I have any problems using it like this or this is the way to go?
Well, I'm open to suggestions but more importantly, I would like to enlighted (if possible) about PHP output compression.
P.S: Sorry for this big testament and for the bad english, I had to translate this from a Portuguese post I did to some other f?rum and I'm kinda in a rush...
