Chmod Calculator – Set file permission with chmod

Chmod Calculator – Set file permission with chmod
0

For most of us, working in Linux or in a shell is not necessarily a daily activity, and that’s totally OK.
I’m not daily working with it either, but occasionally I use one of those funny commands to set the access rights to certain files and/or directories.

This command, chmod, is not super complicated to work with, and is commonly used when working in a shell or terminal on both the MacOS X and Linux platforms. But we need a “magci number” to set these rights. The “magic number” for chmod is also commonly used with FTP programs.

Whenever I use this command, I need to refresh my mind on how to calculate the “magic number”, and I find myself looking for a chmod calculator.
Since I’m lazy at times, I figured: why not have one on my own website?

So I started playing with JavaScript and created this chmod calculator.

Mac OS X – BootCamp CD Eject for Windows

Mac OS X – BootCamp CD Eject for Windows
0

When running Windows on your Mac through BootCamp, you might be searching for the CD/DVD Eject button every now and then, and back in the day (2009) I wrote a little application for that for my own use: BootCamp CD Eject.
This application works with all Windows version as of Windows XP – and you can use this without BootCamp as well.

This little application lives in the Windows Systray and allows you to eject a CD/DVD from a menu or through a key combination. There is also a key combination to quickly put your Windows in standby.

I’m posting the application (free!) since I recently ran into some users that actually had a use for it even 7 years after developing it.

Remotely Wake up your Computers with Wake On Lan

Remotely Wake up your Computers with Wake On Lan

Wake On Lan, the Ethernet standard for waking up (switching them ON) network enabled devices remotely, has (again) gained popularity, especially under NAS/Server users, who use their server or NAS only a few hours a day. Wether it’s to save on your Power bill, reduce your Carbon-Footprint, or to spare your equipment, Wake On Lan is here to stay …

Now come these question though,… how do I enable Wake On Lan on my network enabled device, and how do I send a “wake up” call to my device?

In this article, I’ll try to cover as much as I can – since it can be a pretty hairy process to setup Wake On Lan. It very strongly depends on the hardware and software capabilities of your device. Even though I cannot every device on the planet, I sure will try to help you get started with Wake On Lan.

I had not used the good old Wake On LAN option in a while, until my brother-in-law (Jean-Pierre) was looking for something like that to wake up his NAS.

Most of the Wake On LAN applications I found for him were just too extensive, too complicated, or not free. I wanted just a simple menu in the System Tray (Windows: next to the clock, lower-left corner of your screen) or Menu-bar (MacOS X – top of your screen). Well, after quite a bit of searching I could not find anything suitable or to my liking and I decided to just write something myself.

Timing couldn’t be better, since I just wanted to implemented Wake On LAN in another application – ConnectMeNow (for MacOS X).
Reusing the code, making it suitable for Windows and MacOS X, and wrapping it in a small application was done relatively quickly.

This application has been tested under MacOS X 10.11 (El Capitan) and Windows 10 and it’s FREE.

MacOS X – How to take Screenshots and add Annotations

MacOS X – How to take Screenshots and add Annotations
2

I’ve been asked several times in the past, on how to take screenshot and annotate them afterwards, or how to do a so called “print-screen” to a printer for a hardcopy.

Some users, use screenshots for illustrating manuals, or articles for their website. Some use it to print error messages or odd things happening on their screen. And as with regular paper, some of us would like to annotate the images – add notes, comments, arrows, numbers or circle the important part of the image.

Annotating images is relatively easy, once you know where to find the tools to do this.

So in this article, for Mac OS X users: How to take screenshots, how to add annotations, and some additional related tips and tricks.

Linux System Specifications from the Command Line

Linux System Specifications from the Command Line
4

In the past few weeks, I’ve ran into the need to find out what the hardware or system specifications are of one or the other Linux machine.

I use it every now and then, either on my QNAP, HTPC, Ubuntu machine or even my DD-WRT router.
Earlier this week I even needed it to checkout my old web-server specs versus the new web-server.

Well, with Operating Systems like Mac OS X and Windows, it’s relatively easy to find the specification with the help of system build-in tools that come with a proper user interface. Under Linux this can be more challenging though, especially when there is no graphical user interface – ie. you only have shell access.

In this article I’ll try to go through a few relatively standard commands to checkout your system specs like memory, CPU, video card, disks, etc.

Quickly connect Network shares on a Mac with ConnectMeNow

Quickly connect Network shares on a Mac with ConnectMeNow

In this day and age we are more network connected than ever before – at home and at work. Some of us have network shares on their computers, want to access company network shares, or have a dedicated file server or NAS (Network Attached Storage) to store our shared information or make our backups.

Unfortunately, at times anyway, it can be rather cumbersome under Mac OS X to connect to those “shares” (also known as the so called mounted “Volumes“). In Finder, a server doesn’t always appear right away, we need to go through a list of shares on a given “server”, get confused if we need SMBCIFSFTP, SSHWebDAV, NFS or AFP, and I’m not even mentioning the need to enter a username and password on protected shares.

Additionally, Wake On Lan is being supported as well.

I do have a NAS and I do have several shares on that device and … I just got freakin’ tired of going through each step over and over again. So, instead of complaining, I started looking for an application that would just that – and didn’t find one to my liking. So I just created one … free for all … enjoy!

XBox 360 – Duplicate XBox 360 content

XBox 360 – Duplicate XBox 360 content
2

Alright, this was the problem I ran into …

I have two XBox 360’s; an old Phat one and a new XBox 360E (looked better next to my Xbox One and was for $149 on sale at the time). On both I had the same DLC (Downloadable Content).
On the old one however, the harddrive died, so I replaced it with a new one (cheap 500Gb from AliExpress).

Now normally you can re-download the DLC content onto the new disk, but there are reasons why you’d rather do it this way …

For one, my Internet connection is horrendously slow, so downloading 34 games was not an option – I gave up after having it sit there, downloading content for more than 48 hours and quite often failing.

A possible other reason: The DLC you paid for is no longer available.

Yet another reason (for me): You moved to another country and the DLC is no longer available for that region, yet you still have the DLC on your other XBox 360.

You could also use this method to make a backup of your XBox 360’s hard drive, just in case it dies in the future.

All methods I have found online refer to a special cable you can purchase, or hooking up the drives to your PC. The latter is not always practical, especially when you’re only using laptops and do not have a SATA to USB adapter.

Anyhow, in this method we COPY the content, unlike what the XBox 360 likes to do. It standard MOVES content so it can reside on only one device or drive. Or can it …?

The only thing needed for this process is a USB drive or stick and of course access to a XBox 360 or two.

Note : This method will not allow you to illegally copy DLC from a buddy to your XBox 360, and that is not the intended of this article any way. You will need to be using the same XBox Live account on the other XBox 360, otherwise you will have to transfer the license.

Remove Ubuntu from Ubuntu/Windows Dual boot (UEFI)

Remove Ubuntu from Ubuntu/Windows Dual boot (UEFI)

Some of you may have read my article on how to Dual Boot Windows 8.x and Ubuntu 14.x … which works great, but what if you want to undo this; remove Ubuntu Dual Boot and remove the boot manager?

For example when you’ve decided that running Ubuntu from a USB stick is sufficient, or maybe run Ubuntu in a virtual machine with VMWare, Parallels, or VirtualBox. Or maybe you’re selling your computer and the new owner has no desire to have a Dual Boot on their “new” PC?

In this article I’ll show you how to remove the Dual Boot. I’m doing this based on the way I have installed Dual Boot, but it will very likely work for installations that have not followed my article. No additional tools are needed, like special applications, a repair or recovery CD or a live USB stick.

Do keep in mind though that this article is based on a computer that has a UEFIBIOS” and not an old regular BIOS.

Mac OS X SMB Fix, or How to install SMBUp

Mac OS X SMB Fix, or How to install SMBUp
110

If you’re a Mac user, and you’re enjoying the newer MacOS X versions, then you might have noticed that Apple’s own implementation of SMB simply sucks … it just doesn’t work and for a company like Apple to just leave it this way is beyond me.

SMB is a network protocol, commonly know as “Microsoft Windows Network” or Samba, which allows sharing of files and devices over a network. Most of us use this on our Windows computers and theoretically (it seems) MacOS X should support this as well.

For me it’s to share files with family, friends, or to share media files with my XBMC/Kodi setup.

In this article, I’ll show you how to quickly get started with a working Samba implementation, instead of using Apple’s broken implementation – for this we will make use of SMBUp.

I honestly had zero use for a XBox 360 Controller on my Mac, since I’m a keyboard/mouse gamer … but I was toying with another article (Kodi on Amazon Fire TV) and was looking for a Game Controller for the Amazon Fire TV.

Looking around I noticed that the Microsoft XBox 360 wireless controller for Windows should work with the Amazon Fire TV and with MacOS X. Since I do play the occasional game on my Mac (yes: that is possible!) with Steam, I figured why not give it a try. The controller, with receiver, isn’t all that expensive.

So in this article: How to connect and use an Xbox 360 Controller on MacOS X …

MacOS X – Determine WiFi Connection Speed

MacOS X – Determine WiFi Connection Speed

While working on my DD-WRT project for my NetGear R7000 router, I ran some tests to see what the ideal connection setup for my router would be.

During the testing you’d typically want to see the speed of your WiFi connection, possibly including noise, RSSI, channel, country code, used frequency, etc. and initially it can be a bit daunting where to find this information. But … surprise: this info is readily available on your Mac, no extra software is needed, you just need to know where it’s hidden …

Therefor in this article 4 methods to figure this out on your Mac, without the need to install specific software for the task.

UEFI – Dual boot Windows 8.x and Ubuntu 14.x …

I usually work on a Mac, and when working under Linux or Windows, I resort to Virtual Machines (VMWare Fusion / Parallels Desktop).

Sometimes however, a virtual machine is not up to the task. For this purpose, I have a cheap Acer laptop that came with Windows 8.1. But that is just Windows. So how do I make this laptop dual boot Windows 8 and Ubuntu using Ubuntu 14.x and Windows 8.1?

These are the few easy steps I took to make my laptop dual boot Windows 8.1 and Ubuntu 14.x.

The described method can also be used to run Ubuntu from a USB stick, which works very well when using USB 3.0.

How to use xRDP for remote access to Ubuntu 14.04

How to use xRDP for remote access to Ubuntu 14.04
259

To remotely control my Windows machines, I always prefer to use RDP (Remote Desktop Protocol) as it performs much nicer than VNC (Virtual Network Computing). VNC has this streak of “JPEG” quality and slow behavior, whereas RDP is fast and crystal clear.

RDP is however a proprietary protocol from Microsoft. So how can we use RDP to control our Ubuntu box remotely?

This is where xRDP comes in play, an open source remote desktop protocol (RDP) server. It actually runs VNC protocol over RDP as far as I understand, yet if behaves much better than VNC by itself (possibly because of the used desktop manager). Since Ubuntu 12.10 (if I’m not mistaken), xRDP doesn’t seem to work with the Ubuntu desktop anymore … unless you use an alternative desktop manager. This seems related to 3D acceleration and nobody seems to care (since 2011, according to bug reports).

Note : if you really need Copy/Paste functionality between the two machines, then please use Ubuntu’s default installed “Desktop Sharing” instead (MacOS X users read this forum post).

MacOS X Image Resizer – Right click images to resize and/or email

For those of us coming from the Windows platform, that have used the Image Resizer PowerToys for Windows XP (yeah I know: from way back in the day), here a free application for MacOS X users to have that same functionality as well.

Simply right click an image, choose the desired size and your images will be resized automatically without modifying the original file.

I’ve expended the functionality a little bit, by adding the option to convert a Retina image straight to “classic” (50% size reduction) and after resizing the option to automatically attach the resized images to an email, ready to be send to friends and family …
