Mozilla Thunderbird (portable) - email client (multiple accounts, gmail support, spell checker, tabs, quick filter, master password protection, add-ons, themes, dark mode...)
javaw.exe is the launch process for a java application like Eclipse, Netbeans, or LimeWire. The application generally chooses the size of the Java heap used (via -Xmx size). The default heap if nothing is specified is only about 64MB.
You must have been running something. If you use Process Explorer you can see what command line arguments were passed to javaw which should tell you what the application is.
svchost is what microsoft use to host a service (hence the name)
Try installing process explorer
You'll be able to work out which svchost is pegging the cpu and work out what service it's running.
(Don't worry it's a microsoft app now)
Just stick with the last 2.4.2 release for it. It's a local audio editor, it doesn't really need regular updates.
Here are old releases: https://www.fosshub.com/Audacity-old.html
Here are checksums on audacity wiki to verify files: https://wiki.audacityteam.org/wiki/Release_Notes_2.4.2#Checksums
It removes leftover folders and registry entries
If it thinks the removal of some registry entries is dangerous it will warn you
It batch uninstalls programs and also has a "silent mode" that automatically clicks on buttons in the background
Definitely Vivaldi, simply because of its color tabbing feature and customizability. It is also one of the greatest chromium based browser I've ever seen.
As well as Brave, it has built-in ad and tracker blocker, as well as several security plugins, such as tor. Can't say that I like it because it does not allow installing 3rd party plugins.
Sweethome 3D. I highly recommend it. It's open source, runs on Mac/Windows/Linux and as well as rendering 3D images like you posted, it can create a video walk through of your design. Very cool.
DO NOT try Avg. I repeat. DO NOT TRY AVG.
It will fuck your settings up - install random shit and fuck with your registry for ever. Read this up if you still want to try it: http://www.zdnet.com/avg-security-toolbar-is-the-worst-foistware-ive-ever-seen-7000001055/
Chocolatey is the shit. First time I'm touching a PC/VM I'd always install it first right from command line (no need to even open a browser). Then I can just run "cinst firefox googlechrome peazip notepadplusplus k-litecodecpackmega sysinternals foxitreader libreoffice-fresh paint.net fsviewer -y" go elsewhere and return to a desktop that's almost ready to deal with everything.
Too bad that's not the real adblock. This one is. Ignore the comment war over these two over which one the 'real one' is. Just check the authors out.
Not saying you shouldn't donate to the other adblock guy.
Avoid free VPNs, they are usually very limited in server numbers or data. I have tried a few, did not like it, also, the logging policies are very shady as well :/ Get a VPN that is no logs, for example, FSecure, NordVPN or ProtonVPN, these are unlimited if I remember correctly. Better get a paid VPN because having a free is like not having one at all
This isn't exactly the same as you described, but fences handles the issue in other ways. You can also double-click to hide/show all or a portion of your icons/fences.
Keepass/KeepassXC have this. They use the same db file type so you can try both without having to export your passwords. The only differences I've experienced in my normal usage is that Keepass has a sync feature which makes it a bit easier to keep backups, and KeepassXC has better browser support through the extension.
Windows Sysinternals Process Explorer much better than the standard task manager to figure out which programs are eating your cpu and memory.
imagemagic, all the way. It is exactly what you are looking for. In the command line, you type
convert file1.png file2.png file3.png output.pdf
I'm sure somebody's written a GUI frontend to it anyway that will make it easy if you aren't familiar with the command line. It's open source and cross platform.
This is the standard for obtaining YouTube videos: http://rg3.github.io/youtube-dl/
Web of Trust was brought down because they were stealing and selling the data of users who had installed the extension.
A good way to know if software is decent or not is just running a few searches for it. I find that if software does not appear on https://alternativeto.net/ then I will not bother with it.
As far as protection goes its tied for 1st place with the other big names, overall it's ranked I think at #7 due to performance, it slows apps down. https://www.av-test.org/en/antivirus/home-windows/
Really? Nobody mentioned Syncthing ?
> Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.
tl;dr: decentralized(read: no server needed) and open source Dropbox/GDrive replacement
Cold Turkey is exactly what you are looking for. It physically prevents you from opening applications or certain websites at set times.
Once you set a block you can choose to lock the block which cannot be removed even using command prompt
Open Camera has resolutions going all the way down to 0.1 megapixels. It's open source, doesn't cost a cent, has no ads, a tiny install size and is simple to use.
I would recommend to download the drivers you need from the websites of the manufacturers of your devices. You can find most of them from the mobo manufacturers page anyway.
If you want to save time installing software I would recommend https://ninite.com/
This is what I've used. Near the bottom of the page, there's a list of supported distro's (it's a tab). Windows is listed in "Other".
Jdownloader is the program to use. Downloads from almost every website out there and deals with interruptions very well. Use this ad-free installer:
https://jdownloader.org/jdownloader2
It takes a bit of getting used to - this is a powerful piece of software with a ton of features. Make sure to read the documentation and a guide or two beforehand.
It is worth mentioning that some servers, especially certain file hosting services with optional premium subscriptions, do not allow free users to continue interrupted downloads. Jdownloader can not circumvent such restrictions, but very short interruptions are not going to end the download in many cases with this program, unlike with a web browser.
You should also consider switching over to Firefox. It's more efficient, has better working ad-blocking (Google made intentional changes to Chrome that made uBlock Origin significantly less effective) and is far superior in terms of privacy. It can also continue interrupted downloads far better than Chrome, although it's a manual process (you have to pause and continue downloads that appear "stuck").
Macrium Reflect Free is a great one. I use it personally for drive cloning/backups, and the organization I work for also uses it for backups, system imaging, etc.
>chrome is faster, less ram hoggy.
>prettier design-wise
Nice thing about Firefox is that you can customize the theme.
>all around better in my experience/opinion.
Yeah, well, you know, that's just, like, your opinion, man.
You can set up Syncthing. No flash drive needed. It's the best software for continuous file sync.
For example, you have a Movies folder on your PC. You throw movies into it, and they automatically sync to the movies folder on your dad's PC (which can be a path to that external drive too) as well.
All you need is just to have the software running.
For everyone? Ninite.
For techies and power users? Chocolatey NuGet.
Chocolatey is a package manager for Windows that allows you to install, remove, and update your programs from the command line while taking care of dependencies. You can also use it to create installation scripts that allow you to automatize computer setups.
It isn't quite apt-get yet and it feels kind of hackey but it is very useful.
I'd have to substitute notepad for Notepad++. Everything you love about Notepad, but it also has tabs (and auto-save!) and the ability to be a editor for just about any type of file, with syntax helpers for most anything (html, java, C++, etc).
I also have to throw in LibreOffice. Great free software that has most of the capabilities of M$ Office without a whole lot of bloat. I've been using it for years, ever since OpenOffice went a bit stagnant.
EDIT: Fix'd ugly, ugly links.
EXIFTool is what you need.
Assuming you are using Windows, if you rename exiftool(-k).exe to exiftool(-overwrite_original -all=).exe you can simply drag and drop your photos onto the EXE and it will automatically strip all of the metadata from the image(s).
From the website: Bulk Rename Utility is a free file renaming software for Windows. Bulk Rename Utility allows you to easily rename files and entire folders based upon extremely flexible criteria.
I've used many programs for my note taking over the last 15 years or so, main ones were: KeepNote, Zim Wiki, Evernote, a bunch of other outliners, and most recently it's just been a "notes" project of markdown files in my regular programming editor (phpstorm).
But I was missing the WYSIWYG feature, and I finally found what I've been looking for all these years yesterday... https://typora.io/
These are on that website and you can build an installer that can install them all.
They got some good programs there to get you started try looking into a few a little more in depth.
JPEGView is your go-to. Not only is it incredibly minimalistic and lightweight (even portable), but it allows you to almost instantly view any image in full resolution, switch to next or previous images within the same folder, quickly zoom in with scroll or fit to screen with space, and has a built in editor for adjusting contrast, brightness, hue etc..
It also solves your problem with switching images after zooming in if I'm not mistaken.
I've been using it for a few months after having the same issues as yourself with the default image viewer and It's completely replaced it.
Been using AnyDesk for quite some time and I'm happy with it. It's free for personal use and available for various platforms. Last but not least, it doesn't require registration.
Here's the link in case you want to check it out.
Personally speaking, I use TinyWall. Nothing phones home that I don't allow.
TBH, I forgot that Audacity could connect to the internet - the news about the Muse sale was surprising today.
You should read this before you bail, though - https://github.com/audacity/audacity/discussions/889
Synergy is great, it's just not free. Just make sure you get it from the source and not some random site. - There are several other programs that do the same thing, I'm just not sure if any of them work on Mac. - Multiplicity, Mouse Without Borders, Barrier...check out https://alternativeto.net/software/synergy/
Create a Parted Magic LiveUSB key with Unetbootin (the ISO is less than 200 MB, so an old 256 MB flashpen will do just fine). Boot off of that and open the program named GParted. It's really straightforward, I think you'll know what to do. It will probably take a long time, because everything you have on D: has to be moved to the left.
Parted Magic is a Linux distribution, so your partitions are named differently. Your hard drives are named /dev/sda, /dev/sdb, /dev/sdc and so on. Partitions on you hard drives are named /dev/sda1, /dev/sda2 and so on.
If you only have that 500 GB HDD with those 2 partitions, C: should be /dev/sda1 and D: should be /dev/sda2.
Stardock's Fences - I know that I don't 'use' this software everyday, but keeping my desktop icons clean and organized in a logical manner is a must. I can't stand a cluttered desktop.
You want the best?
3D YouTube Downloader.
They have batch and regular version. It's the best software and i've tried ALL of the suggestions in /r/software.
And you're welcome
MediaMonkey all the way. I use it to rip all my CDs and convert them to FLAC. I organize them with proper tags and file names. I then sync the collection with my iPod, which means that all the songs are automatically converted to mp3s.
I've been using Free File Sync.
To automate the backup process, look in the tutorials section of the site where they have a video tutorial to set up a scheduled task to do the backup (or real time sync for backup as soon as files are changed).
Atom and Sublime Text are both pretty and quite functional. I personally give a slight edge to Atom because I like its package diversity and it's open source, but both are really great
I think this is the third time I've given the same answer to three different problems on this sub today by Autohotkey could do that.

This, you aren't supposed to be able to edit .pdf files. If you want a document for editing you would pick a different filtetype. There is an opensource pdf creator that I use occasionally... PDFCreator, which prints any document to a pdf file. And I also believe there is an opensource pdf to word converter, but I've not used it as I have no need to edit .pdf files. But this would allow you to convert a .pdf to word type, edit it, and then print back to .pdf using both of these programs in conjunction.
Fences, must have for Windows desktop icon managment. Especially if you play full screen games that force you into low resolutions, which causes your icons to clump up and scatter everywhere. Fences lets you make regions on your desktop and stops icons from going out of those. Letting you make a "browser" section "games" section "apps" sections, etc. If a low-res app in full screen breaks your tidy layout of icons, it moves everything back automatically.
Started playing Final Fantasy 8 again lately which does just that, I'd be driven insane if I had to fix my icons every time.
My mother in law, running XP, had the same problem. Turned out to be a root-kit virus. I went to Kaspersky and downloaded a free rootkit detector and remover sure enough it pulled it out and Chrome worked again. Interestingly the anti-virus never picked up on it. But that is common from what I learned.

I am preaching Everything as well
Here are few videos showing it in action
I actually learn python and made poor linux alternative partly because of it.
its fucking amazing, I would not even call it search, once you get used to it, its more like a navigation tool... as mostly I use it not to find something I lost, but to navigate instantly somewhere that would take too many clicks...
This is the utility that I personally use. Just select the files and you're off. The interface looks REALLY intimidating, but don't worry--it's actually pretty simple once you stop freaking out (assuming you're like me :P ) and look at each box. For your example, for your request all you'd need to do is edit box 5, "Remove", to have the "First n" box be "6". It will show you in the top-right window what the new file/folder name will be (in green), then it actually applies the change when you hit the big button in the bottom-right.
The GUI does support recursion if you check the "Subfolders" option in the "Selection" box (#12). There's also a command-line utility from the same people, but I've never used it.
http://www.bulkrenameutility.co.uk/Screenshots.php has worked really well for me. Does name appending, sequential numbering, string pre/appending to file names, fairly sure it can even do regex replacement on filenames too.
There's X-Chat and several others, but really, the client-side IRC protocol hasn't changed since Windows 3.11 for workgroups was new, so you're not likely to see any major alterations to client programs - after all, the people who ~~use~~ program IRC clients aren't really concerned with aesthetics
Like /u/lostguru said; "apples to oranges". LaTeX is for serious typesetting, like if you are writing a book on calculus or physics and need all the letters and symbols and graphs to be printed exactly they way it looks on your screen. There's a more user-friendly front-end for it called LyX.
I'm currently using PDF-XChange Viewer, which is free, lightweight, and awesome, and has a search function which looks like it does what you want.
I pay about $40 a year for a service called Private Internet Access. Has desktop clients for Win and OSX, compatible proxies for iOS and Android (I think) plus a torrent proxy. Very happy with the service. The free ones I've tried are slow, get taken down, or are generally unreliable.
Try FixExec, a tool by BleepingComputer.com specifically designed to repair this sort of damage.
Also, you may be able to execute programs by changing the extension to another one of the executable file extensions, such as .scr
, .com
, or .pif
. Windows will execute these file extensions just like EXE files.
In what way do you want this other player to be better? Video quality? Power efficiency? Simpler/advanced options? Ease of use?
Personally my favorite video player is MPC-BE You can get it here http://sourceforge.net/projects/mpcbe/ I use that with Madvr video renderer
Recommend CDBURNERXP or IMGBURN if you're just looking for CD burning capabilities.
MediaMonkey is a full suite for managing your media, so unless you're looking for an iTunes-type replacement it is more than you likely need.
Check out WinCDEmu.
Basically after you install it, you just double-click the ISO file and it mounts it. Then when you're done, you just Eject the ISO (ie go to My Computer, right-click on the virtual drive and choose Eject). Simple, fast, and efficient, haven't used anything else since I found this.
Edit: also supports CUE, NRG, MDS/MDF, CCD, IMG formats, and best of all, it's free and open source.
Mozilla Thunderbird (portable) - email client (multiple accounts, gmail support, spell checker, tabs, quick filter, master password protection, add-ons, themes, dark mode...)
I've done it. It's pretty easy.
@methinks2015, what does it matter what the purpose is? Hes not asking anyone "should I do this"..
Edit: Also I'm pretty sure the "purpose" is to have 3 OS'es installed.. durh. As to why someone would want that is totally up to them. In my case I like to be up to date on what's happening with each OS.
Portable software can be taken with you, e.g. on a thumb drive. Back when I was in high school, I had a thumb drive with portable versions of Firefox, Open Office and various handy tools with me at all times. That way, I had my favorite software with my settings, bookmarks and private data, which would also leave no traces on machines I used them on. I could use a better browser than the mandatory Internet Explorer on school PCs. With the start menu of portableapps.com, I even had a comfortable menu instead of having to go through folders.
The disadvantage of portable software is that there is no installer that automatically creates shortcuts on your desktop, in your start menu and in the list of installed software. It's less convenient and it's easier to be "messy" with portable software, if you don't take care to carefully place it in appropriately named folders. That's it. Otherwise, there are no disadvantages. The software is the same, apart from where it saves its data, which has no impact on operation or performance.
I'm still using portable versions of Firefox and Thunderbird, simply because I can easily transfer them to a new PC or Windows installation, without having to jump through any hoops or use an online service to transfer my bookmarks, add-ons, messages and settings. I just manually create shortcuts, that's it.
No. No, you don't.
Use the x86 version. It has much better compatibility because of some ffdshow codecs.
Congrats. You should now be able to decode errrrything. Including the new Hi10P h264 profile that's just started appearing. This new profile doesn't work with DXVA (decoding using the graphics card), so CoreAVC is your weapon of choice. Step 6 involves tweaking subtitle options to increase the resolution. This is compulsary if you watch anime fansubs, otherwise you will end up with a artifacty, upscaled mess.
If anyone's struggling, let me know. This is complicated stuff XD
youtube-dl is the real deal, everything else uses it.
Here is a guide that I wrote on how to use it: /r/software/comments/9lxktm/how_to_download_entire_youtube_playlist/e7asu6g/
There are also GUI's that use it:
But it might be useful learn how to use the original thing.
I personally prefer MPC-HC over other media players due to it being quick, fairly simple to use and light on system resources. Plus, it plays all file formats that I can throw at it.
I'll admit that MPC-HC might not be much of a looker (since it inherits the UI from its now discontinued parent, MPC). But with MPC being open source, there's a variant of it out there called MPC-BE which is easier on the eyes (picture).
foobar2000 will also sync iDevices. Assuming you don't have too much protected stuff from the iTunes Music Store, you should be able to get rid of iTunes entirely, if you want.
As far as converting files, this isn't CSI. There's no way to magically put data back into a file that wasn't there in the first place. If it sounds like crap as mp3, it'll just sound like crap as any other format.
I think it's great you did this, but I find it kind of ironic that the website does not use HTTPS / TLS, and there are no cryptographic signatures or even hashes for the downloads as far as I can see. Consider using Let's Encrypt if you don't want to pay for a certificate.
It sounds like you're interested in using a VM for your everyday computing, which isn't really what they are meant for. The security benefits of running a VM come from the fact that they are "sandboxed" from the normal computing environment which means that they cannot affect (or even detect) files or programs outside of their little virtual space. If you are running everything within your VM then you might as well not be using the VM because it's just using more resources for nothing.
I can't think of any reason for a typical user to run a VM at all. If you are interested in making your computer and online activities safer, your time would be much better spent reading a couple articles about computer and internet safety.
Also I can't recommend highly enough that you use a password manager like LastPass or KeePass. They will allow you to use extremely strong passwords and never have to remember any of them again. Using weak passwords and reusing passwords across services is one of the worst, and unfortunately most common mistakes that people make when it comes to securing their data.
I like keepassXC since it has built in browser integration in addition to the generic auto fill of Keepass. Both are compatible, so if you decide to move you can just open your Keepass database in KeepassXC or vice versa.
It's an NT6 (Vista and up) feature.
I'd always assumed it was the work of Mark Russinovich, like ProcMon, but now that I look, its inclusion in Vista would actually place it before Microsoft aquired Winternals.
You should be able to suss them out of an active wifi connection using something like fing.
https://play.google.com/store/apps/details?id=com.overlook.android.fing&hl=en_US
But if they aren't active and they're locked you'll have to tumble the OS to get into settings.
Why not link directly to the OBS Project website? Instead of a site that does this.
^(I know there are scripts to prevent sites from doing that but I'm just curious)
You could also use uBlock for this. The filters could be hard to write if you're not familiar with CSS selectors and the built in wizard doesn't do what you want, but it's pretty flexible.
E.G.
mangadex.org##.chapter-feed__container:has-text(Bilibili)
Applies to mangadex.org
and blocks the element with the class chapter-feed__container
that contains the text Bilibili
uBlock uses this syntax: https://adblockplus.org/filter-cheatsheet#elementhiding
VLC, 7-Zip for me on those. F.lux, Unchecky, Chrome, GIMP, Launchy, Atom (over Notepad++), Bunch of IDEs (Android Studio, IntelliJ, Python)loads of software that I have are awesome. I use https://ninite.com/ when doing fresh installs on a PC. Anything, in particular, you want to know?
Cool although I have a few disk space analyzers:
Space Sniffer
WindirStat
Scanner
DiskSpace Fan Free version
Disk Explorer (From Glary Utilities)
edit: What black magic is this? Only 10KB? Nice! I guess the crown of the smallest program I have goes to this, sorry kkrieger.
Blender? Not the easiest to get used to, but it has plenty of features and it is free.
Good starting point to learn:
https://www.blenderguru.com/tutorials/blender-beginner-tutorial-series
Davinci Resolve. https://www.blackmagicdesign.com/products/davinciresolve/
Excellent software. You can do loads with the free version, if you need more advanced stuff, the Studio version isn’t that expensive in the grand scheme of things- and well worth it for some of the extra recovery and clean up filters.
openbrodcaster is free and open source and is a great software but if you want to pay I recommend bandicam it is a very nice software that can record screen or capture opengl directx content
There is a tool from system internals called 'ZoomIt', this would work perfectly and its free.
edit: to enter drawing mode w/out zooming is 'ctrl+2' (that's the default, it can be changed)
I really recommend Imdisk Toolkit. It's free, open source, regularly updated, and supports mounting hard drive and floppy disk images, in addition to CD and DVD images. It also supports creating a RAM disk, if you'd find that useful. It can both provide a virtual view of an image stored on disk and read/write data as necessary, or it can copy the entire image to main memory and provide a virtual view of that (which, in some situations, would be significantly more performant than streaming from the hard drive).
I use barrier, an open source fork of synergy. The server you mention for both barrier and synergy is running on your own computer and does not send any data outside of your network, so in that sense it is safe. Barrier does end-to-end encryption for free, while synergy requires the more expensive 'pro' version. Without encryption there is a danger that someone on your network could snoop on your keypresses or even take control of your system, but with encryption enabled you should be safe.
Libre Office is OK. You can get a portable version at PortableApps so you don't even need to install it (can work from a USB key).
If you just need the equivalent of Word & Excel, Wps Office is a lightweight alternative and has excellent compatibility with Microsoft file formats (.xlsx and .docx).
<code>youtube-dl</code> supports a very large amount of sites.
This is probably the closest you can get though, "any site" just wouldn't be possible. There are way too many variables that come into play.
> And you can use the portable version of CCleaner which doesn't install anything
Or even better, don't support them and their scummy practices in any way and use BleachBit instead
It's a command line tool available for Windows, Mac, Linux. WMV to MP4 could look something like this:
ffmpeg -i input.wmv -c:v libx264 -crf 23 -c:a libfaac -q:a 100 output.mp4
You should have a look at the documentation to figure out which set of parameters gets you the best result.
If you prefer a GUI I would suggest Handbrake.
We used to do this in the late 80's using sox and SunOS 4.
These days I guess you'd use one copy of VLC acting both as a local player and as a network streamer and have additional copies of either VLC or even standard (win|mac) media player listening to the network stream.
media monkey. i just throw music in a folder and i tell the program to sort it by artist, then make a subfolder by album and done. you just have to make sure the mp3 tags are accurate. there are scipts that do all kinds of stuff to the tags too.
Are you looking for something that looks like a calculator, or something that does the same computations as a calculator?
If it's the latter, may I suggest Octave?
Won't cost you a thing, does everything any calculator can do and there are graphical front-ends to choose from.
As 3141592652 says they all pretty much keep logs at least for a while (Usually 2 weeks) but if you want some free VPN's to use check out this website http://www.vpngate.net/ almost all of then you can use OpenVPN with and download the config files straight from the website hope it helps you out!
I'm not quite sure what you mean......but for no other reason than I like it and you may find it handy. Have this. http://ejie.me/
EDIT: TABS in windows explorer. No more shuffling through 30 windows. Now you can shuffle through 30 tabs. XD
MEGA, or even better, Tresorit (as it's Swiss-based).
But if you encrypt your files yourself with Cryptomator, any cloud provider works. Depending on how trusting you are, encrypting yourself is a better choice. Going with an E2EE & zero-knowledge provider would also still be a good choice for an extra layer of security.
Balabolka saved me many times from hassle. There's also a portable version available on the developer's home page or you can get the Portable .paf format from the Portableapps.com.
Libreoffice Writer is what you want.
https://wiki.documentfoundation.org/images/3/35/WG40-WriterGuideLO.pdf
Download the Libreoffice Suite to have it all.
It's all free. Yes, I did say it's all free.
Well, VLC is a video player mostly. I would use Mx Player on Android for that.
For audiobooks I used Smart Audiobook Player, though I haven't used Android in a few years. It was very good to me, though.
This is kinda like asking where you can get free gasoline for your car.
This is (IMHO) the best VPN provider, and by far the best deal out there - NordVPN, 2 years for $79, up to 6 devices, supports Windows, macOS, Android, and iOS- ;2year=&coupon=2YDeal2017
I personally like to use Steganos Locknote.
If you are using a projector or other display, one option would be to use OBS. https://obsproject.com/ You add a window capture source and point it at the program you are using. Keep this program on your screen, keep the OBS window on the projector. Right click on the live OBS preview and click Fullscreen Projector then select the projector display. When you move around the window capture, anything behind it will be black. You could also add a background image behind it for the presentation if you'd like. Add a static image source and place it below the window capture source, resize the image to cover the background, and it will replace the plain black background.
Hope this helps/is an option for you.
