![]() ![]() Download and Install P圜harm IDEįollow all the steps below to download and install Pycharm IDE on Windows. It provides amazing integration with Docker for running the code over them. You can now start P圜harm from the /opt folder instead of /home/pi/Downloads.īut that’s not very convenient, which is why I’ll show you how to create a shortcut in the main menu.Also, the professional edition of P圜harm supports Python web frameworks, such as Django, web2py, and Flask. We have to use a terminal because the default user on Raspberry Pi (pi) doesn’t have the right to write in the /opt folder. Sudo mv /home/pi/Downloads/pycharm-community-A.B.C /opt/ĭon’t forget to replace A.B.C with the version number you have. If there isn’t an installation wizard, it’s recommended to move them to another folder (/opt for example). You rarely need the files in it more than once.Īs soon as I have too many files in it, I delete everything or at least move the files into a subfolder to make sure I don’t need them.Īnyway, it isn’t a good practice to keep your applications in the Downloads folder. I don’t know for you, but in my case, I consider the Downloads folder a temporary folder. After installing P圜harm, there are at least two things you can do to improve your experience.

Install Javaīefore doing anything else, we need to install Java. Replace A.B.C with the version number you downloaded (tip: use tab to auto-complete the file name). If you prefer the command line, you can also start a terminal and run: Choose “Extract here” and wait a few seconds:Ī new folder will be created containing all the files.Find the P圜harm archive and right-click it.Open the file manager (there is a shortcut in the top bar).You should get a tar.gz file in your Downloads folder.

Successfully enticing the general population to open a malicious email attachment with the promise of receiving an illegal product may be a first. FortiGuard Labs has now begun to encounter offers of fake vaccine passports as lures in email scams. While this is not necessarily new, unlike other criminal activities, this strategy is going mainstream. Because of this trend, opportunistic cybercriminals have begun selling counterfeit vaccine passports on the black market.

There have been many debates on various travel forums whether these are appreciated by the elites and are actually used or if they are just a waste of resources. It has been several years since United sent out luggage tags to their premier members and back in those days they were sent out automatically. Once your order is accepted, you will see a confirmation screen just like the picture above. On the page there is a button where you can click on to order yours. Alternatively, a shortcut is to log in from the link below: To order yours, log in to your UA MileagePlus account and go to MY United and then Premier Status Tracker. ![]() This is the first time since 2019 that United is sending out luggage tags to their elites, but it is not automatic. I guess this new design is more subtle and humble and does not exude the sense of someone flaunting a gold badge tied around their carryon bag. This new branding has a horizontal orientation with a very plain background but with the status printed in larger and bold text. The old design has a vertical orientation and places more focus on the background color reflecting the status of the badge. However, these new ones have a completely redesigned branding. The picture above shows the two different brandings, with the current one on top, and the old one on the bottom.įor many years, the design looked almost the same year after year, with maybe only subtle changes in the patterns. I hope one day UA will bring them back! New Branding Unfortunately, they have been residing in the history books for maybe a decade. These were very nice, and I really miss them. Some of you who have been premier members with UA for a long time might remember the larger 2” by 3.5” personalized badges with your name printed on them. For many years leading up to that time, the size has remained the same. The last time United sent out luggage tags to their elite members was in 2019. These are the small size tags measuring approximately 1.5” by 2.5” and is exactly the same size as those in previous years. The slot where the plastic loop strap is tied to is very thin and I lose an average of maybe one a year. I think they should just give every elite two of them as they break easily. MileagePlus 1K and Platinum members receive two luggage tags inside the package while Gold and Silver only get one. The package arrives in a long envelop with a cardboard folder displaying pictures of the airlines’ worldwide destinations. My wife and I are Gold and Platinum and we both got ours today (March 15), while there are reports on some travel forums that some 1K’s (higher than platinum) have not received theirs. It appears to me that when you will receive it depends more on your geographical location rather than your status. It could take up to a few weeks for the initial batch to be delivered. Luggage tags for United Airlines’ MileagePlus Premier Elite Silver, Gold, Platinum, and 1K members began arriving in the mail on Monday, March 13, 2023. ![]() ![]() In a relational database, it is important to be able to identify an individual table row.
