We recommend and review some laptops/notebooks suitable for data science and machine learning.
Firstly, we state the 4 core important specs (specifications) for laptops for data science and machine learning.
1) RAM: Should be 8GB or higher.
2) CPU: Should be Intel Core i5, or even better Intel Core i7.
3) Storage: Should be at least 256 GB SSD.
4) GPU: Optional, but good to have for deep learning. (Note that Mac GPUs are not usable for deep learning.)
RAM and CPU are necessary in order to conduct computations successfully and within a reasonable time. Storage is necessary to process big data which can potentially be several gigabytes. GPU is useful to speed up deep learning, but is optional since there are many cloud or server options available.
For concrete recommendations, we recommend the following 5 laptops. Certainly, there could be other laptops that are equally suitable for data science and machine learning, do comment below if you have a good suggestion!
iMovie is a great free movie editor for Mac. However, an annoying bug is that when two video clips are put together, there can often be “corrupted” frames, glitch, or even choppy video between the two clips.
Simple solution to iMovie Transition Glitch
There are some complicated solutions online, such as re-importing the video clips in certain formats.
However, a simple solution that I tried and tested to work in most cases is to try trimming off a few seconds from the start of the affected video clip. Or even adding a transition effect where the problem arises may work.
To explain more precisely, suppose the problem arises in between A -> B, where A and B are video clips. Then, you can try trimming off a few seconds off the start of video clip B, or adding a transition effect between A and B. (If there is already a transition from A -> B, try removing it!)
Another solution to iMovie Transition Bug
Another solution that I tried and works in some cases, is to export the movie via File -> Share in Best (ProRes) Quality, with Better Quality Compress.

Overall, this is the ideal printer for work from home, as well as homeschool purposes. It is even more ideal for those who don’t want additional features such as scanner and fax. By not having those features (which you may not need), it has a very economical affordable cost. Especially when you factor in the long term savings from cheap and long-lasting ink refills.
If you do want copier, fax and scanning features, then you can consider the Canon PIXMA G7020 instead, which is basically the Canon G5020 with the additional features.
Hundreds of researchers attempted to predict children’s and families’ outcomes, using 15 years of data. None were able to do so with meaningful accuracy.
Now a new study published in the Proceedings of the National Academy of Sciences casts doubt on how effective this approach really is. Three sociologists at Princeton University asked hundreds of researchers to predict six life outcomes for children, parents, and households using nearly 13,000 data points on over 4,000 families. None of the researchers got even close to a reasonable level of accuracy, regardless of whether they used simple statistics or cutting-edge machine learning.
“The study really highlights this idea that at the end of the day, machine-learning tools are not magic,” says Alice Xiang, the head of fairness and accountability research at the nonprofit Partnership on AI.
Note that Windows 10 (Home) is free (you don’t have to activate it) and you can use it with only very minor restrictions.
Overall, the process to install Windows 10 on a Mac (using VirtualBox) is much easier than I expected.
Total time taken: Around 30-40 minutes (possibly faster if your download speed and RAM is fast)
Total cost: $0
Total space needed: Around 10-20 GB is needed initially. VirtualBox allows “dynamically allocated disks” which are faster to create and can grow to larger sizes. For example, if you set 50GB as your disk space (but only use 10 GB) then it will only occupy 10 GB on your Mac.
When the Mac (or MacBook) is running for a long time, it is very liable to do one of the following things:
The problem is that your Python program or R program running in the background will most likely stop completely. Sure, it can resume when you activate the Mac again, but that is not what most people want! For one, it may impact the accurate calculation of elapsed time of your Python code.
Changing settings via System Preferences -> Energy Saver is a possible solution, but it is troublesome and problematic:
Have to switch it on and off again when not in use (many steps).
Preventing sleep may still run into screen saver, screen lock, etc.
Vice versa, preventing screen lock may still run into Mac sleeping, etc.
The solution is to install this free App called Amphetamine. Despite its “drug” name, it is a totally legitimate program that has high reviews everywhere. What this app does is to prevent your Mac from stopping, locking or sleeping. Hence, whatever program you are running will not halt till the program is done (or when you switch off Amphetamine).
It is a great program that does its job well! Highly recommended for anyone doing programming, video editing or downloading large files on Mac.
