One of the handy tools to have is virtual magnifying glass. It can be a solution when one need to enlarge only a portion of the display. For example, if you want to show some video or demo on a large screen, and the application does not support making it visually bigger. Or it can be a necessary tool for people with low vision.
There also exist a portable version (with portable apps).
- different browsers might give different results (eg. video might work with firefox but not chrome)
I was positively surprised about this book “Enterprise Cybersecurity“, and I can happily recommend it to anyone working with security management. There are more than one way to do the things, and this book is showing one alternative way on how to connect the dots between different concepts in cybersecurity.

Even though there are several references to NIST framework, it is still used as part of the bigger program, and would not restrict to use any other framework as a base.

Six Thinking Hats method can be useful when taking a discussion/workshop with several participants and at the same time you want to make sure that you will get some concrete results out of the session. This method nicely gives a structured approach on how to run the session, instead of letting participants to go from one extreme into another.
To get a quick introduction, I highly recommend to see one of the following videos:
The picture below is from the first video.
A concrete example is available here, and a powerpoint template is here.
How the session could look like, in which order to use the hats etc, then one could have a look here. With some examples:
- blue – definition of subject
- white – ready knowledge
- green – generating ideas
- blue – definition of problem
- white – available info
- green – possible solutions
- yellow – reality check solutions
- black – weak points solutions
- white – connect to info
- blue – draw conclusion
- blue – topic of decision
- green – offer alternatives
- white – factual situation
- yellow – suitability alternatives
- black – un-suitability alternatives
- red – making the decision
- black – assessing decision
I recently purchased a flip mirror and I find it very usefull when trying to take photos with telescope. In this setup one can both view the target visually and take photos. It takes some time to get the camera and visual eyepiece adjusted, but after that is done, then one only need to flip (turn) the mirror.
When using high magnification, then eyepiece projection is good way to achieve that. The picture below shows the 2 eyepieces that are needed in this kind of setup. Camera is connected on the left (not in picture).
The photo below shows other ways to connect a camera to an eyepiece. They do work, but are not as practical as flip mirror with DSLR. It is also possible to combine these two, and use these adapter to flip mirror in place of DSLR …
With the help of an Activity tracker it might be easier to achieve your weight loosing goals. These trackers take care of the tedious work to log everything. Just place the activity tracker on your wrist, and start walking…
This blog will show some real results, when using an activity tracker during the first 1 million steps.
This huge number of steps came as pleasant surprise, and was a good milestone to write this blog. When buying the activity tracker, the intention was to loose weight; especially by walking.
In this period of 1M steps, one could loose weight for about 7-8 kg, which is close to 1kg/week.
The figure below shows the weight (kg) for the 56 days (close to 9 weeks).
The figure below shows the number of steps for each of the 9 weeks.
The figure below shows the estimated extra Calories (C = kcal), over BMR, for each of the 9 weeks. (The numbers are given by the activity tracker).
- One needs at least 2 different tracks: one for regular short walk (min 1h), and the other for longer exercise (min 2h).
- If you can afford, then take the long track. It is more difficult to get started than to continue walking…
- (in my case, my favorite tracks are short walk “1h15min” and long walk “2h35min”)
- Don’t force the walking speed too much, the duration of walking is actually even more important as this is about fat burning and not competition
- There is such a thing as limited speed of change (weigth loss), even if you walk a lot one day, you will not loose all weight in one day; the affect takes longer to adjust
- Yes, you can eat. If you increase your exercise (walking), then there is less chance to get more weight. Yes, sometimes the weight jumps after party, but it is not permanent.
- Yes, you can have day(s) without exercise as long as you try to maintain some routine and monitor that you don’t start to gain weight too much.
- At the end, it is about routine and habits. Walk when you feel for it, it can clear your mind 🙂
About activity meter
- the activity meter on the wrist is only the data collector. The collected data is synced with the server, and that location varies depending on company. Some persons might prefer to choose to select a manufacturer that keeps the exercise data in EU…
- The estimated calories varies depending on if you have HR (heart rate) measurement active or not.
- With HR active, it records more calories
- the battery does not last “long” if you have HR, GPS or bluetooth active
- bluetooth can be used if you install an android app
