What are some simple but Useful Technology Hacks?
If you download a PDF file and you see it ends in .exe delete it. It a virus. Have a long lecture you have to watch on YouTube? Go to the settings and opt for the 2x speed. It will be little faster and funny at first time but you can easily understand what is said and watch it in half of the time. Too lazy to read the full article? The Chrome extension TLDR will give you a short and quick summary of the long articles online. If you accidentally close a tab CTRL+SHIFT+T reopens it. If you lost an Android phone in your house and it on vibrateyou can find it by going to Google Play Android Device Manager Ring. If you in any flight number into Google you can see where the plane exactly is. Hope it helps Rony!! italic
What preferably exciting things can we do with C pointers that we can't do with Python?
Before MS Office switched to the *x formats (docx xlsx pptx etc. - which are zipped XML files you can open them with 7-Zip and take a look inside) they just dump data structures directly to a file function pointers and all. A Python reference cannot be saved to a file as it not data (while pointers are - for example theyre often 32-bit or 64-bit integers and can be treated as such if desired). Now what they were doing back then would be a bit problematic today due to ASLR (Address Space Layout Randomization) but at the time it was a good solution IMHO. Also you cannot create a reference to an arbitrary memory location they can only be created from objects that Python knows about (which is a problem if said object is actually created by the hardware e.g. like we have with memory mapped registers). HOWEVER as long as you stay within Python little walled garden and don need to interact with the outside world you can actually simulate pointers if you want just create lists to represent your memory and use indices into those lists to represent your pointers mem = None * 124 code mem42 = h code mem43 = e code mem44 = l code mem45 = l code mem46 = o code def prnt(ptr) code while (memptr != None) code print(memptr end=) code ptr += 1 code print() code code code hiptr = 42 code prnt(hiptr) code hello code If you do italic actually need the outside world there cs That one can give you C pointers in Python.
What is Apple's version of Microsoft office?
Apple productivity suite is called iWork s . It contains a word processing app called Pages a spreadsheet app called Numbers and a presentation app called Keynote. There are versions that run on Mac desktopputers the Cloud iOS phones and tablets. The individual apps of the suite are free and should be downloaded individually from the Apple app store. The iWork suite prioritizes making your documents look good. Although their native file format is proprietary they are capable of exporting files in the same .docx .xlsx and .pptx file formats as used by Microsoft Word Excel and PowerPoint. I rmend creating documents in the iWork suite then exporting them in a Microsoft Office file format to share with others. Your document will look heads and tails better than the ones submitted by others. Featurewise the iWork suite has the basics covered well. What missing are the long list of features that few but power users ever employ. Although the apps support AppleScript there are many fewer objects methods and properties exposedpared to the VBA and Office-js used by Microsoft Office apps. Keynote is arguably better than PowerPoint. Although its initial feature list was a weak copy of PowerPoint Steve Jobs requested new features for each product introduction. These new features were then included in future releases of Keynote. Jobs had a well-deserved reputation as the best presenter in the tech world and he used these new features to makepelling visual presentations.

Why is SQL in such high demand when I can use Excel and do half of the work, and never have to enter code again? I can literally write a macro and have a button.
Hello Excel is good for an especific purpose. But being an expert hammer man doesn makes all the problems nails. Excel is just a tool as SQL it is just a regular tool. Nothing less nothing more. And they have their proper usage and their abuses as well. Excel proper usage is for simple data exploration and dive. Use it for anything else and its usability starts to crumble. Both in machine and people terms. Is not only that your solution will not grow well. It will be difficult to maintain and keep it floating. It going to be expensive because excel main aim is to make it easy for you to explore your two dimensional data; it doesn provides you with data structures other systems interfaces or performance. It confundes the data representation with the inner live of the data. It going to be a big fat mess! SQL any engine in the other hand is a full blown database relational system. Which means it will not only keep your data in order it will make it easy to interrelate it and mix it. Besides your image of SQL is a table and functions. Which makes it pretty easy to think this is equal to excel. But there end all possible similarities. A database counts with optimization systems like materialized views indexes several levels of interops with many different techs and is the core of any modernputer system. To use SQL is to build the foundations for a future analytics system that will overgrowth it current size. Is like putting the steel structure for the building of data you are foreseeing to make. To use Excel is to keep yourself toying with legos and pretend you can build the empire state with them. Answer will be Yes you can. Technically you can. Now try and go for the rooftop if you dare.
