I had a problem with my libapache2-mod-mono install freezing during install when trying to run ASP.NET applications on Ubuntu.
The workaround for this is to open another session and restart/reload apache:
root@xyzio:/home/xyzio# service apache2 reload root@xyzio:/home/xyzio# service apache2 restart
This is what I would see and the session would freeze at the [OK]:
apt-get install libapache2-mod-mono Setting up libapache2-mod-mono (2.11+git20130708.6b73e85-2) ...

I bought a 1 year subscription to Private Internet Access (https://www.privateinternetaccess.com) about three months ago in order to protect my privacy when traveling and to ensure that my information was protected at my house. I live in a high density neighborhood where I can see at least 10 WiFi access points from my laptop. At home I regularly check my router logs to ensure there are no new users but I’m paranoid that someone will hack in and cover their tracks.
Private Internet Access gives you access to VPN clients in many countries. They assign you a username and password when you sign-up and this is used to log into their servers worldwide. They state that they keep no logs and store no data. However take this with a grain of salt and avoid passing sensetive information via non-HTTPS connections. For additional protection you can daisy-chain your own server in the flow to get more privacy.
I chose Private Internet Access because they were highly rated at the VPN sub-Reddit, they have a representative on Reddit answering questions, and because they offer clients for all major operating systems.
So far I’ve had no issues and they say they don’t throttle bandwidth. My usage is light but I have a feeling I might be restricted if I tried to pull 10TB of data through their servers.
Private Internet Access is relatively cheap. At one year, it is cheaper than hosting your own VPN server and definitely much less hassle. A one-year subscription costs $40, one month is $7, and six months costs $36. It is apparent that they steer you towards the 1 year plan. They occasionally have discounts so keep your eye on the Reddit VPN page.
The Android client is very easy to use. Its usage can be summarized in three steps:
1) Download and install from the Android Play Store
2) Launch app and enter your username and password
3) Click the ‘Connect’ button
You can optionally select a server but it defaults to picking the fastest host.
A nice feature is that the app shows the current up/down transfer rate as well as the total usage for that session. However when transitioning from wireless to the cell network and vice-versa the app introduces additional delay as it gets disconnected and needs to re-authenticate with the VPN server. This is annoying because it usually happens when I’m walking out of a building checking my messages or getting directions.
The Windows client is equally easy to use. Installation and execution can be summarized in four steps:
1) Download from Private Internet Access
2) Run executable
3) Enter your password
Linux client setup proved to be difficult. Rather than providing a client, PIA provides instructions to perform the setup. While the instructions worked in a graphical Ubuntu VM on my laptop, they do not work on my non-GUI DigitalOcean VPS. I was able to figure out an alternate way to perform the setup however it took a lot of digging. It would be nice if PIA incorporated instructions for manual setup and connection on their site.
- It is cool to connect to server in Romania and see the Google Romania page show up. However using it is impractical due to latency
- Multiple sites around the world to reduce delay wherever you go
- Easy setup
- Android client introduces delay as it re-authenticates when transitioning between data providers
- Private Internet Access says they don’t log data and that they would reject PRISM monitoring requests. Take this with a grain of sand and always encrypt your data! This does not guarantee that your data is not being monitored at PIA’s outgoing ISP or that your home computer does not have a keylogger. Or if they are really watching you!
It is hard to see if connecting to Private Internet Access is protecting me. I’ve used it at home, around town, and when traveling in hotels, coffee shops, and airports. As far as I know none of my data has been compromised. I think it is hard to see if it effective, but it is an additional layer of protection and you protect yourself just by being more difficult to hack than the next guy. Ultimately the only way to be safe online is to not go online!
I recently bought some Mighty Plugs Earplugs to help block noisy co-workers at work and to use while traveling. The earplugs are marketed as the ‘highest blocking‘ and ‘most comfortable‘ earplug in the world. They have a sticky putty like consistency which helps them mold to the shape of your ear. This stickiness allows them to attach to your ear without being too invasive.
My choice was between purchasing these or the Howard Leight Laser earplugs. I ended up getting the Mighty Plugs because I hadn’t tried them before and they seemed interesting. I’ve been using the Mighty Plugs for six months and so far they’ve been good. They mold to your ears and are good at blocking external sound. However they are expensive, sticky, and get nasty after a while.
I’ve decided to go with a pros/cons format instead of my usual review style. Read more below.
- Mighty Plugs don’t go too far into the ear canal. The earplug molds into your ear cavity and canal to create a full seal. They form a good seal but can come out while sleeping or chewing. The Leight Laser plugs are more invasive and can also come out in similar conditions.
- 20 year shelf-life (so they say). Leight Laser earplugs will probably last longer due to their synthetic construction.
- Mighty Plugs last 25-30 uses but they pick-up dust and residue over time which reduces their effectiveness. Leight Laser earplugs last 2-3 uses and you can afford to have a new pair whenever you want. You also are not pushing in old buildup into your ears. Over the long run the Howard Leight earplugs are cheaper, 6 pairs of Mighty Plugs at 30 uses means one pack of 6 can be used 180 times. A box of Howard Leight will last at least 200 uses and you can get a new pair every time.
- Sticky lanolin leaves a tacky residue on fingers and on ears.
- Earplus are sticky so they pick up dust, stuff from your fingers, and earwax from your ears. Re-use means you are pushing this stuff into your ears regularly. You also have to ensure you have clean hands before you start or you’ll contaminate the Mighty Plugs for the rest of your uses.
- Need to knead them for 30-40 seconds before first use and then 15-20 seconds for each subsequent use. Leight Laser earplugs are ready to go in about 2-seconds: squeeze, insert, and hold in place for a moment.
- Very expensive – 6 pairs for $20 plus $5 for shipping. Leight Laser earplugs are $20 for 200 with free shipping if ordering over $25.
- Shipping is padded by $1 when ordering from Amazon.com – Mighty Plugs performs a bait and switch to show matching price from their site but then rip off the user via shipping. This is probably done to make up the money they pay to Amazon for their commission since Amazon does not charge commission on shipping charges.
This is a decent earplug. However, the tackiness, residue build-up, and expense are major detractions. Their tendency to break their seal is about the same that of regular earplugs coming out. I think they are good for office and other clean environments. They are useless for outside work due to their tendency to pick up dust from the air and your fingers.

I bought the Logitech Trackman Marble Mouse after finding the Logitech Anywhere Mouse MX to be too small for my long fingers. Excessive use was causing my fingers to cramp up which is not fun after a long day at work. It is too bad because I loved the Anywhere Mouse and found it to one of the best mice I’ve ever used. A co-worker suggested the Trackman because it was ambi-dexterous and it accommodates long fingers. I bought the mouse from Amazon.com for $23.
The trackball is very unassuming, there is a red ball at the top you manipulate with your fingers and two buttons on each side. One side is meant to be clicked with your thumb and the other side by your ring or pinkie finger. The top is made of a slightly textured plastic that doesn’t get
uncomfortably hot with use. The bottom is the standard mouse black plastic with three anti-slip pads spread around it. The entire unit is sheathed in shades of an unassuming gray that exudes a sense of boredom.
The trackball feels like what you’d expect from a device made from cheap plastic. If feels decently comfortable in my hands, I can rest the palm of my hand on the base and stretch my fingers around it to reach the ball and buttons. The buttons are typical Logitech, the have a linear feel and click with very little drama. Each click is accompanied by a precise ‘snick’ that provides auditory feedback of the action’s execution. I can tell that these buttons are well made and that I can count on them to perform reliably for years.
The ball is smooth but is a little heavy and has quite a bit of friction. I have to put in more effort necessary to move it around, I can’t just flip the ball and move the mouse all the way across the screen. The ball is removable and this is a good thing because gunk tends to build up on the supporting pegs.
Becoming proficient in using the mouse takes a day or so, precise pointing takes some practice but you can go from opening the box to clicking links in Google in a couple minutes. The main left and right click buttons are easy to find and click. The 2nd set of buttons, meant to be used for back/forward while browsing the web, are useless. Clicking the buttons requires me to contort my hand beyond a comfortable level that is intolerable for any amount of time.
The ball is heavy and has a lot if friction. This makes it hard to scroll rapidly across the screen during regular use and I can feel fatigue in my fingers towards the end of the day. A big issue is that gunk from your fingers builds up in the ball supports which further impede progress. I find myself cleaning the ball supports at least once a day. The heavy ball becomes aggravating after a while and I feel like Logitech should have put more work in this part of the design.
Overall the Trackman Marble Mouse is a decent trackball considering the price. It has no fancy features and it does the work of the equivalent two button mouse. Having a sealed sensor means that the buttons or the ball will wear out before the sensor breaks. it also means that we’ll have precise sensing for the life of the product.
Annoyances include the extra buttons are useless and I think they were put there just for marketing reasons. Gunk tends to build up in the ball supports which requires frequent cleaning. The base doesn’t fit well in my hand – It would have been nicer if the base had been wider or had a slight dip for the base of my hand.

Update 9/14: These instructions no longer seem to work at Linode. Please leave a message in the comments if you see a mistake in my directions.
I’ve written about using Apache to proxy connections over SSH in order to hide sensitive information in public places. For an extra fee you can gain additional anonymity on the internet via companies like Private Internet Access which provides multiple VPN gateways for around $40/year without the risk of hacking or mis-configuration that comes with doing your own setup. You also get the ability to use VPNs in multiple countries and US locations thus further obfuscating information.
Private Internet Access has instructions on how to set up a VPN on Ubuntu using Network Manager. However I’m using a server install at Digital Ocean and I don’t feel like installing the desktop just to use Network Manager. In addition there is setup required to allow you to access the VPS while still routing outgoing data through the VPN. This should also work at Linode. Here is how to do it:
1) Install open-vpn : apt-get install network-manager-openvpn
2) Download a copy of Private Internet Access’ config files or if their site is down, here. Unzip the files in a new directory. The zip file contains everything you need to access their VPN servers without dealing with Ubuntu’s Network Manager.
3) Now you configure your VPS so that any traffic that comes to the VPS is responded to by the VPS. Otherwise once you start your VPN any attempt to connect to the VPS will be answered through the VPN which is not what the connecting software expects.
Type this at the prompt:
ip rule add from x.x.x.x table 128
ip route add table 128 to y.y.y.y/y dev ethX
ip route add table 128 default via z.z.z.z
Where x.x.x.x is your public IP y.y.y.y/y is the subnet of your public IP address ethX is your public Ethernet interface z.z.z.z is the default gateway To get the x, y, and z use ip route: ip route show. The last three lines of the output will look something like this:
126.96.36.199 via 127.0.0.1 dev eth0
188.8.131.52/1 via 10.155.1.5 dev tun0
127.0.0.0/24 dev eth0 proto kernel scope link src 127.0.0.1
Match the color coded output to the ip commands above. You need to type these in every time you restart your VPN so it helps to save them in a shell script.
4) Optional: Create a password file. You can create a password file to supply OpenVPN with your login info If you are lazy and don’t feel like entering a password every time you connect to Private Internet Access. To do this, make a file that contains your username on the first line, password on the 2nd line, and nothing else.
5) Start OpenVPN using one of the config files from step 2. Each config file is set up to connect to one of the VPN servers run by Private Internet Access. You can specify your password file from step 4 using the auth-user-pass argument. Here is what I use to connect to their Romania server:
openvpn –config Romania.ovpn –auth-user-pass password_file
Finally, check your IP using their ‘Where’s My IP‘ page.
