The ULTIMATE CheckPoint Commands Cheat Sheet

The ULTIMATE Check Point Commands Cheat Sheet This page is a list of the most useful and common configuration, monitoring and troubleshooting commands used on Check Point products. The sources include Check Point product documentation, admin guides, Secure Knowledge articles, Advanced Technical Reference Guides (ATRG), TAC cases and other experts in the field who are kind enough to share their knowledge and expertise.

Fix issue with Lightroom and Photoshop CC crashing on launch

With the launch of Lightroom CC ( also called Lightroom 6), Adobe introduced a slew of new features, most notably Photo Merge HDR and Photo Merge Panorama. The excitement soon died as users couldn’t launch the new application using the Creative Cloud Desktop. Lightroom and Photoshop would display the splash screen momentarily and then crash. The problem was compounded by the fact that there was nothing in the logs that pointed to a possible reason for this behaviour. Strangely, this issue did not plague every one who upgraded to Lightroom CC. If you are one of the unlucky ones, read on to find out how to fix this issue and get Lightroom CC up and running. Please note that the solutions provided below are only for users on Mac OS X. There are two solutions floating around on the web and both are from Adobe themselves. Although the first solution can be found on Adobe’s website, it worked only for a handful of users. The second solution, which seems to work for pretty much everyone, can only be obtained from Adobe by having a chat/calling their customer support. Now, we all know how quick that can be. So follow the instructions below to fix this issue. Solution 1 Try this first as it is easier and seems to work for a few users. If it doesn’t work, try the...

Paulo Travels Sleeper Bus between Hyderabad and Panjim, Goa Review

This is a review of the sleeper bus and service provided by Paulo Travels on my recent trip from Hyderabad to Panjim, Goa and back. The pictures were shot from my phone. Hyderabad to Panjim, Goa  I decided to board the bus at Miyapur so I could directly get on the bus. If I were to start from my place, I would have been taken to the bus in a very small and cramped mini bus, and I wanted to avoid that. For those who are not aware, private buses are not allowed within the city limits in Hyderabad before 10 PM. So, the passengers are ferried to the bus in small mini vans/buses from various locations in the city. I reached Allwyn Junction, Miyapur just before 7:30 PM. The bus was scheduled to depart from Miyapur at 7:30 PM but arrived only at 8 PM and left at around 8:30 PM. First impressions of the bus and the berth seemed to be okay. Nothing extraordinary but just comfortable. There’s a luggage rack over my feet where I put my camera bag. Happy about it as I didn’t want to put the camera bag in the boot. The curtains and berth were very dirty though. It looked like they haven’t been washed in years! There’s also a little gap next to the luggage rack where I squeezed my laptop bag. Two problems solved!...

Fashion photography workshop at Hyderabad

It has been a while since I took my camera out and so I started looking for places around Hyderabad to shoot some landscapes. As I couldn’t find any interesting spots for landscapes, I went to Meetup to see if I could go on a photo walk or something similar. That’s when I found Hyderabad Fashion Photography Workshop for beginners organized by Rakesh Kurra. Although I am not into fashion photography, I thought I’ll give it a try as it could help for when I shoot portraits of friends or family. The cost of the workshop was Rs. 3000 for the day so it felt like it was worth it, and it wasn’t too far from where I lived. Also, I was beginning to get desperate to go out and shoot some pictures without having to travel hundreds of kilometers. Getting there  A map was included on the Meetup group page from Google Maps and I just followed till the destination. Or so it seemed. The workshop was to be held at Prakash Farm House. The location given on the map was about 5.5 kms away. Strike 1. You can see from the map that the actual location was 5.5 kms away from the location we were shared. The red pin being the location shared and the other end of the route being the correct location. The workshop was due...

Fix Audio control issue on BackTrack 5 R1

The latest version of BackTrack 5, R1, has an issue with audio controls. While I have experienced this problem on the GNOME version, I cannot say about the KDE version. When you make a fresh installation of BT 5 R1, the audio control applet in the panel does not work. The slider moves, but sliding it does not affect the volume. Also, clicking on Sound Preferences displays a message ‘waiting for sound system to respond’ and does nothing. However, the volume can still be controlled in any media player that you use. I use Rythmbox. The fix for this is pretty simple. 1. Navigate to System > Preferences > Startup Applications on the main menu. 2. Click on Add. 3. Give a name. I used ‘Fix Audio Control issue’. This is only to identify it, in case you run through the list at a later time and wonder what the entry is for. 4. For Command, type ‘/usr/bin/pulseaudio’ without the single quotes. 5. Click on Add, and then on Close. 6. Logout to close the X session, and restart it by typing ‘startx’ without the single quotes. That’s it.
