Can I use older MySQL workbench with newest MySQL server?

MySQL newbie here.

  • I’m using Ubuntu 16.04 (64-bit).
  • I’ve successfully installed MySQL Community Server 5.7 and MySQL Community Workbench 6.3.

Unable to find these answers in the MySQL forums. I’ve asked this on Stack Exchange and it was suggested that I ask here instead. I’ve searched on Ubuntu Forum and here also but did not find an answer.
One would think they are common questions but maybe not. Additionally, I cannot find a way to ask a new question on the MySQL Forum.
I’ve spent a ton of time reading/researching/installing/uninstalling and reinstalling MySQL and community workbench on Linux Ubuntu 16.04 (64-bit) and do not want to lose the momentum I’ve gained. I’m actually making forward progress after a week or so of trial and error working on this up to a few hours per day.

It appears that I cannot load MySQL Community Workbench 8.0 without Linux server installed. That seems to be one of the requirements if I understood correctly.

  1. Can anyone tell me if MySQL Community Workbench 6.3 will work with MySQL Community Server 8.0 on Ubuntu 16.04 (64-bit)?
    I would still like to upgrade and use MySQL community server 8.0 if I can.

  2. Can I use MySQL Community Server 8.0 on Linux Ubuntu 16.04 32-bit?

I’ve spent many hours googling it and looking on MySQL Forums but couldn’t find the answer.

Thanks much. …Rick

No information displayed for older purchases on eBay – Why?

If i click on some of my previous purchases on Ebay, i cant see the original listing, this tends to happen with older purchases.

Any idea why this is, and if there is anyway around it so i can see old purchases ?

Newer Preference Panes on Older MacOS? [closed]

I am trying to copy Desktop and Screen saver preference pane of Catalina to Mojave. But When I copy and open system preference , I get nothing in that Preference pane. Is there any solution?

Can a mac boot from an external drive, if the external drive is running an older version of macOS?

In general, can a make that has a newer version of macOS on it boot from an external hard drive that has an older version of macOS on its main drive?

For example, could I boot High Sierra from an external hard drive on a mac that has Catalina installed on its’ main drive?

Why? I have a mac desktop running Catalina that’s a work machine. I’d like to use the hardware for personal use, and run macOS using an external hard drive, using an older version of macOS that I’ve purchased myself, but when I try, I see the “Prohibited” sign on the drive when I try and boot from it.

I tried to use the external drive with a macbook running El Capitan, and it worked fine

EDIT: The model is “iMac Retina 4k, 21.5, 2019”

Does user feedback always get worse over time as a website gets older?

We have ‘Is this useful?’ Yes / No feedback. We have targets from senior management to improve this, but it is not getting better no matter how many UX and content improvements we make and errors we avoid. I’ve also noticed that visitors are less and less likely to submit feedback as time goes on. So, is this just a rule for websites as they get older – does feedback worsen over time? My theory is that when the website was new, people were keen to provide their feedback but once they had done so once there was no reason for them to do so again, and so over time the feedback becomes biased towards those who just want to complain.

memory – Will a newer CPU with a few cores or an older CPU with more cores compile code faster?

I am a university student studying computer science, and I am just starting to explore the world of servers. I currently use a 2018 15″ MacBook Pro as my main computer for writing, compiling, and running code (2.6 GHz 6 Core i7, 32 GB 2400 MHz DDR4, Radeon Pro 560X 4 GB GPU). My MacBook Pro is great for my daily driver, as it’s fairly quick at compiling code, although with the fans running at high speeds for the duration of compiling and running the code.

I have recently discovered X11 forwarding (this article explains it a bit), which gives me the ability to view GUIs from applications running on a server without using a VNC viewer or anything too laggy. Given X11 forwarding, I am now wondering if running an IDE on a server and connecting to it with X11 forwarding would yield better compilation times than my laptop. I’ve been looking at an HP ProLiant DL380p Gen8 that has dual 8-core Sandy Bridge Xeon processors (Xeon E5-2660’s), as well as 64 GB of DDR3 ECC memory. The stock GPU in the HP (Matrox G200eH) seems abysmal compared to my Radeon Pro 560X, but I’m fairly certain that Java, Node.JS and the like tend to rely much more heavily on the CPU than they do the GPU. I also know DDR3 memory runs significantly slower than DDR4 does, but I’m still wondering if the additional 10 cores, 20 threads with HyperThreading on the HP would yield better compilation times than my MacBook Pro would. My house has gigabit ethernet, so networking shouldn’t be a bottleneck. Additionally, I would probably put an SSD in the HP for the operating system and apps to run on, so storage speed shouldn’t be a bottleneck either.

My question is this: would running my IDEs on a dual CPU server with more CPU cores, albeit much older CPUs and hardware as a whole, be faster than running my IDEs on my MacBook Pro with fewer cores, but newer hardware? I almost exclusively use the JetBrains suite of IDEs (based on a custom Java Runtime Environment), mainly IntelliJ IDEA, WebStorm, and CLion.

Similarly, would the HP be faster for HandBrake video encoding and transcoding? I’m a teaching assistant and converting MOV files to mp4’s is something I have to do regularly that runs my laptop quite hot and takes a long time.

Jenkins fails to start on Windows Server after Java Runtime update uninstalled older version of JRE

I have a Jenkins Server running on Windows Server 2012 and Java prompted me to update to a newer version (jre1.8.0_261 to jre1.8.0_271) and during that install it asked to uninstall older versions (for security reasons) which I allowed it to do. When I restarted Jenkins service it failed to restart. Error log indicates this Informational message:

Starting C:Program FilesJavajre1.8.0_261\binjava.exe -Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "C:Program FilesJenkinsjenkins.war" --httpPort=8080 --webroot="C:Windowssystem32configsystemprofileAppDataLocalJenkinswar"

And this error:

Service cannot be started. System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) at winsw.Util.ProcessHelper.StartProcessAndCallbackForExit(Process processToStart, String executable, String arguments, Dictionary2 envVars, String workingDirectory, Nullable1 priority, ProcessCompletionCallback callback, Boolean redirectStdin, LogHandler logHandler, Boolean hideWindow) at winsw.WrapperService.StartProcess(Process processToStart, String arguments, String executable, LogHandler logHandler, Boolean redirectStdin) at winsw.WrapperService.OnStart(String() args) at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

The informational message gave me a clue to the problem: Jenkins is pointing to the older version of Java location here: C:Program FilesJavajre1.8.0_261

However the folder is empty, most importantly there is no bin folder present (no doubt due to the aforementioned uninstall).

The newer version here has the full java binaries: C:Program FilesJavajre1.8.0_271

How do you get Jenkins to point to the new JRE?

bios – Blinking cursor/underscore on older computer when booting off Windows Installation USB Key prepared with the Windows Media Creation Tool

In attempting to install Windows 10 on a newly-installed SSD in an HP Pavilion DV9000 laptop, I created a Windows Installation USB Key using Ventoy and the Media Creation Tool. While I’m able to boot into Ventoy, and select the Windows.iso, I’m then faced with a blank screen with a blinking cursor.

What I’ve tried, without success:

  1. Waiting 20 minutes to see if something changes
  2. Using a different, similarly-prepared USB Key, in a different USB port
  3. Using Balena Etcher to prepare the USB Key
  4. Using a Windows ISO with both 32 and 64 bit versions of the OS
  5. Using Rufus to prep the USB Key with Partition Scheme: GPT and Target system: UEFI
  6. Look for options in the BIOS related to UEFI (there were none)
  7. Look for a BIOS upgrade (none officially available from HP since the machine is over 10 years old)
  8. Check to see if Q4OS loads (it does)

Is it possible to update your iphone older than the latest version but newer than the current one?

Let’s say I’ve just got a brand new iPhone 8. When I wanna update it can I update to iOS 13 or only the latest version will show up there?

Is there a container solution for running Flash apps in older browsers on Windows 10?

Flash apps will stop working in modern browsers after Dec 2020. One of our products relies on a 3rd party solution that manages its assets via a Flash app served by a web site hosted on the app server. We are working on a replacement, but this current solution is installed at 50+ customer sites, and there will be no way to get the replacement implemented at all sites until sometime in Q2 or Q3 of 2021.

A number of years ago, I briefly used a desktop app that would run registered apps (mostly browsers) in a type of containerized environment (before I knew anything about Docker). The main idea was to allow website devs to test on older versions of different browsers without having to host in VMs. This would seem to be a perfect solution. An older version of say, IE could be run with Flash enabled, but neither the Flash app, nor the older browser would have access to the host machine’s OS, and should be safe from Flash vulnerabilities, but mainly, the OS wouldn’t have to be an older OS, with its own vulnerabilities. (Yes, I know that Chrome puts Flash in a sandbox, but since support for Flash is going away, local IT would need some assurances)

For the life of me, I can’t remember the name of the product. Does anyone know of such a product, or a different solution to this problem? That is, safely running a Flash app after Dec 2020.
