c++ – How do I make Visual Studio 2019 Community Edition default to 64-bit mode for new projects?

This question is much asked and much answered, but I can’t find a single answer that really seems to get to the nub of the problem and which really answers the question as asked. Which is to say, if I simply Create New Project -> Console App -> (choose a name for the project) -> Create then the project is in 32-bit mode. It’s trivial to click where it says X86 in the tool bar and change it to X64. Problem solved. You don’t even have to go into Configuration Manager or any similar complicated strategies that many answers through the years have suggested. But still, I have to change the X86 to X64 every single time I make a new project. And in addition, the very process of defaulting to X86 has created a gazillion little files and folders for the X86 version of the project that really aren’t needed. So the question is not how to make a 64-bit app. That’s extremely easy. And the question is not about how to convert a 32-bit app into a 64-bit app. That’s also extremely easy. The question is how to configure Visual Studio 2019 Community Edition so that a new project defaults to 64-bit in the first place.

By the way, all the answers on the Microsoft forums start out with “Open the C++ project that you want to configure.” But there is no existing project if what you are trying to do is to set the default for new projects. Also, I did find default.vcxproj and played with it a bit. I didn’t see anything there that established a default of X86 vs. X64. But I did see that the X86 entries were in front of the X64 entries. I moved the X64 entries in front of the X86 entries, but that did not change the default. It did change the order of the way entries were displayed when I clicked the X86 vs. X64 box in the tool bar. Another promising file was shared.vcxproj. It appears that it may hold the default, but there I haven’t yet found any forum messages suggesting that it should be changed to solve this problem.

How to upgrade from Ubuntu 14.04 (32-bit) to latest Ubuntu Budgie (64-bit)?

Ubuntu 14.04 (32-bit) is installed on my laptop along with Windows 7. I have barely used Ubuntu, but I’m on it now since Windows is troubling me.

I was looking for a Ubuntu flavour that is light-weight, and I found Ubuntu Budgie, which is also pretty sweet looking, hence I opted it.

I’d be highly grateful to you, shall you could give me exact steps on how I can update to the latest version of Ubuntu Budgie (64-bit version.)

Please let me know if I need to update Ubuntu 14.04 as well.


-When I was trying to update the OS using Software Updater, I would get the error, “Requires installing from untrusted sources.” And I’d have two options, “Settings…” (which leads to the Software Updater) and “Close”.

Related Queries:

-Does all the flavours of Ubuntu require the ‘original’ Ubuntu to be installed, or they are stand-alone operating systems?

-I need an operating system which is ligh-weight and can run most Windows softwares. Is Ubuntu Budgie a good pick or should I go for something else?

macos – How old are Macs that cannot run 64-bit applications?

In this aspect, Apple “retreated” a little when it switched to Intel processors. At that time, All G5 PPC based Macs were 64bit, and the introduction of the first Core-Duo brought new 32-bit Macs to the market, when they were already phasing out 32-bit. Not for long though.

I clearly remember Steve Jobs Keynote in WWDC 2005, apologetically explaining the move to Intel, to be mainly due to “the solid processor roadmap presented by Intel to him, versus the declining interest of IBM in low-energy desktop computing”.

Last, my friend, you can very confidently forget about 32bit if you’re developing an application. Xcode’s “standard architecture” for a Mac target is 64bit only, and Apple has neglected the Obj-C runtime in 32bit for few years already.

This means – no ARC, no auto synthesis of Properties, fragile isa objects, and much much more. Building Universal or 32bit imposes grave limitations on your development.

applications – Samsung Galaxy M11 and Samsung Galaxy M01s not able to install 64bit apps from google play store even while having 64bit chipsets

Samsung Galaxy M11 has a Qualcomm SDM450 Snapdragon 450 chipset while the Samsung Galaxy M01s has a Mediatek MT6762 Helio P22 chipset. Going to their websites, on Qualcomm and Mediatek respectively, shows that they both support 64bit. However as mentioned in the title, the two phones are unable to install 64bit apps from the Google Play Store. I am suspecting that the reason for this is because their OSs might be 32bit. (I can’t check personally because someone else has the phones and I am trying to solve a problem for them.) If that is the case, is it wise to flash a 64bit OS to the phones to be able to run 64bit apps?
Below are the links to the chipset specs on their respective websites:



networking – Wireguard VPN for home network with raspbery pi4 8Gb (64bit)

I’ve been trying to set up a wirguard VPN on my home network and been having a frustrating time I think I have solved all the ususal issues but I’m still not able to access the internet or things on my home network when I’m apparently connected to the VPN.

After I couldn’t get it working myself I re-imaged my drive and tried PIVPN’s install script, unfortunately this does not work with with 64bit raspberry pi OS I’m running because I’m on the 8Gb pi4. I don’t think the dkms module in the package repo is built for 64bit arm because I couldn’t get it to install so I built it from source which worked. Kernel 5.4 is used in the 64bit pi os buster image at the time of writing so wireguard needs dkms modules. PIVPN still wants to install the dkms module from the repo if you build them manually or if you update to a more recent kernel which has them already built in (I tried 5.10 with sudo BRANCH=next rpi-update and rebooted after any kernel changes) so I gave up on PIVPN and went back to trying to do it myself.

Common issues I’ve checked:

  • Port 51820 is forwarded to my pi on my router (UDP)

  • My Dynamic DNS is pointing to my home IP – I can ssh in to another host on my network with my public address

  • I think the key pairs are correct, I’ve double checked manualy and the connection appears to work from the peers I’ve tried unless key authentication fails silently which I doubt would be the case.

  • net.1pv4.ip_forward=1 (I didn’t change ipv6)

  • I haven’t set up a firewall on the pi yet so that’s not in the way

Here are my config files:


Address =
ListenPort = 51820
# DNS = ip.of.home.router # tried with and without, also not sure if this is supposed to be local or not
PrivateKey = "Server"privatekey=

# eth0 is the correct name for my network Interface
# I have tried it with and without these lines as some guides I have read include them an others don't and I'm not clear on what exactly they do
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

AllowedIPs =

peer config file

Address =
# DNS = ip.of.home.router # tried with and without, also not sure if this is supposed to be local or not
PrivateKey = "peer"privatekey= 

PublicKey = "host"publickey= 
Endpoint = mydomain.me:51820
AllowedIPs =, ::/0
#PersistentkeepAlive = 60

I enabled the systemd service for wireguard with sudo systemctl enable wg-quick@wg0 and this reports itself as active when I check with sudo systemctl status wg-quick@wg0.

(I sent this to my phone vi QR code with qrencode -t ansiutf8 < /etc/wireguard/peer1.conf to test the connection from the outside the network using mobile data)

I’m still pretty new to networking stuff – Have I missed something that should be obvious here?

Apparently dynamic debug logging is a post kernel 5.6 thing so I’m going to try again on kernel 5.10 with the logging on so I can try and get some error messages that point me in the right direction while I wait to see if any of you good people have any help to offer – Thanks.

Unable to install Steam on latest 64bit desktop version of ubuntu for PI4

I’m using the desktop 64bit version of Ubuntu Linux for raspberry pi 4 (8G) (Latest version as of the 26th of December 2020) i can’t download Steam, the Linux version from their website, and the one from Ubuntu’s software store. I’ll be talking about both. for the website download, it says i don’t have libc.so.6, and for the Ubuntu software store, it says that it’s “missing the following dependencies:” but it doesn’t list any dependencies, it just ends the message. any suggestions, I barely know anything about the terminal and almost all “fixes” for these issues don’t seem to work. any ideas?

Upgrading Windows Server 2008 Standard (32-bit) to Windows Server 2016 Standard (64-bit)

I’m trying to upgrade my windows server 2008 standard 32-bit version to windows server 2016 standard 64-bit version. The server is currently running as a secondary domain controller as the primary has failed. I was hoping I could do an in place upgrade but I am now realizing that upgrading from the 32-bit to the 64-bit is not possible.

If I were to reformat and start fresh what would that mean for all my workstation computers? If I remove all of my machines from the domain, do the server upgrade, and then re-join all the machines to the new domain does that mean there’s going to be new profiles on every workstation computer and thus seem to the end-users as though they have brand new machines or after re-joining the new domain (with the same name) will their existing profiles continue to act as they did before?

Lastly, depending on the answer to the previous question should I be doing an upgrade from windows server 2008 to windows server 2012 R2 and then an update to Windows server 2016? Or upgrade to Windows server 2012 and then update to windows 2016? The question being that I don’t think I have windows server 2008 R2 so should I be going to windows server 2012 R2?

Install VirtualBox on lubuntu Alternate 64-bit Version 19.04 as a host

I am going to install lubuntu Alternate 64-bit Version 19.04 on the HDD of a device. It will be the only installed OS from that machine.

I would like to ask which other packages I will need to install on for the lubuntu Alternate 64-bit Version 19.04 in order to use VirtualBox, with all its features.

I would like to use lubuntu Alternate 64-bit, because the device is not so powerful.
Thank you. Regards.

linux – auditd rules for both 64-bit (b64) and 32-bit (b32) architectures

I’m looking at the OpenSCAP Security Guide for CentOS 7:

Under “Record File Deletion Events by User” (as an example), it provides this auditd rule:

-a always,exit -F arch=ARCH -S rmdir,unlink,unlinkat,rename,renameat -F auid>=1000 -F auid!=unset -F key=delete

It advises to set “ARCH to either b32 or b64 as appropriate for your system.”

I have a 64-bit system (uname -m returns x86_64), but checks fail unless I include rules for both b32 and b64:

Title   Ensure auditd Collects File Deletion Events by User
Rule    xccdf_org.ssgproject.content_rule_audit_rules_file_deletion_events
Result  fail

I’m wondering why the b32 line is needed. I tried testing this by setting the architecture to i686 and deleting a file, but it appears to use the 64-bit syscall:

touch audit_i686
setarch i686 rm audit_i686

I’d like to to understand the reason for the 32-bit architecture line and be able to demonstrate the reason for it to any skeptical sysadmins.
