How can you draw a diagram for research journal?
An easy option using software that you may already have would be to put it together in Microsoft Powerpoint. It has all the shapes you need apart from the probability distribution function and makes it easy to them with arrows. To reproduce the probability distribution function you could either find one as clipart on the web (and cut out any unwanted parts using the tools available in Powerpoint) or use the curve tool in Powerpoint to approximate it. Once you have the diagram set up as you need it you can save or export the slide to an image format. There are better more specialised drawing tools and there are free tools available if you don't have Powerpoint (GIMP is quite powerful for instance) but Powerpoint is what I use for this sort of diagram because I already have it and know how to use it.
How can I add a thumbprint signature to a PDF?
That is so easy way to falsify a digital document. The least advanced technique slow but easier is to print the document stamp the thumbprint and scan the document. The proper way to sign a digital document is to add on in digital signature. italic However for some non legal purposes you can add a signature using either a PDF editor there are some of them free to use or an . You first have to save an from the disk; you may need to handle document layers scale the thumbprint. An place it on the chosen place. I have done similar operations using LibreOffice Draw and GIMP. Also Linux PDF Chain tool aids in adding a background over any pdf file you only need to design properly the background or stamp to add.
What is a good upgrade over Microsoft Paint?
Depending on what your focus is you could go a few different ways for an upgrade. I'm going to focus on open-source but talk about free alternatives. So I see three main ways you could go for an upgrade you might consider taking all three so you can gravitate to what works best for the task at hand. If you are strongly in the charts but still want some art tools you might consider libreoffice. It is basically Microsoft office but open source. One of the programs is Draw. It has tools to make many traditional diagrams like decisions trees and mind maps easier. It is also going to be a little bit more friendly with . Google has a similar drawing package Drawing but I find it too simple. I am used toplex software packages so that could just be my bias. Paint .net is generally excepted step up from paint on window. The big problem is that it is only ok for personal use so I don't rmend it. Pinta is great alternative as is kolourpaint or luxpaint. All these similar but the feature that will really help you is layers. It will speed up layout by not always drawing of what you just drew. Aside that the major advantage here is these programs are basically light versions of Gimp and they are most similar to paint and how you have done things in the past. Inkscape is the middle ground option. It is a scalable vector program so the brushstrokes and objects you draw will be discreet objects that can be edited after the fact. Things like the shape color line and weight are not set in stone after you draw that line. They are all repositionable so they are have the abilities of layers. It does what it does well but can be somewhat to a somewhat illustrated or cellshaded style. This would work well for diagrams and give a lot of freedom anything else you want to do. This bit here might not be of too much use. Looking at these option this is how I see it. I would be a bit concerned about being limited by Libre Draw but I think it would be effective at doing what it can do. My experience has been I hit little things I can really do or the features get in the way of doing what I need to do. It's been the same any similar version. Using something like Pinta doesn't feel precise but can feel quick. This is very subjective. I can be accurate to the pixel but it doesn't generally allow the same amount of tweaking and fine tune of shapes as Inkscape. They are both very different approaches. Re Gimp So Gimp is basically the next step beyond Pinta andpany. Gimp does add a lot of photo editing elements but also has a much stronger layer system a much more evolved brush system better selection tools some vector based tools tablet support and the list goes on. This makes it a very versatile piece of software but other software does individual elements better. The vector tools in Inkscape are way better than Gimp particularly because the vector tools have so many roles to play in gimp. I don't really use pinta or that kind of software often because Gimp replaces it nicely but I do use Inkscape.
For a man who hates C++, how is it possible to do OOP programming using C while reserving efficiency?
The base of OOP the basic idea of it is data encapsulation. And this can be clearly done in C while you encapsulate your data inside of modules. Like FILE is the perfect example for a encapsulated abstract data approach to this problem. OOP is a paradigma that an ideology. You don need ideology to do things. Ideology often has nothing to do with the idea behind that. Lets say Social in Socialism isn social at all if you look at the millions of dead in Stalin Russia Mao Pol Pot Cambodia and the millions of deaths in South America or anywhere else. Social that ising from Humanism which is based on some basic social ideas to live in amunity and care for the weak and poor. Which might be directed back to Christianity or some kind of religion but I prefer to draw it back to living inmunities in the animal world where this is an evolutionary advantage. Social behavior is good for life good for your species. Dogmatic ideology is not. I don want to make this about politics but just to give an example outside of the field ofputer science where this is showing . The name and intention the ideology and fuss about something can in the end not serve its rea purpose its spirit. OOP is a programming paradigm which is a nice word for ideology. It doesn give you opportunities it takes them from you. And gives you a bit of syntactic sugar in return like the foul deal that settlers did with native Americans trading glas perls for valuable stuff. Your choice of language I support very much. You are doing good. But you have to be careful not to mix up your implementation layer with your application layer. See from a pragmatic view you can do everything with C. But that doesn mean that you have to switch to an other language the real answer to it is to spice your language up and start to play in teams. Application layer HLL language I take her Lua as an example but also the spreadsheet calculation language is here. You can do that in C or implementation layer Hardware layer optimization and debugging of (2) Asm optimization with OpenCL Cuda Verilog chipset and hardware interaction implementation of special functions that are best implemented in Asm directly (processor flag reacting stuff like Bigint mathemathical operations for example pushing your spreadsheet data on the GPU and so on like LibreOffice does this). ordered-list Abstraction is a tool of the application layer. There it belongs where not the real work is done but the configuration the dataflow the ad hoc reprogramming. You have there also a userbase with lower educational level towards system programming you have to use a simple language C++ does this it mixes 1&2 and outes a bad mix of the disadvantages of both layers. The implementation layer has to be clean and simple. A line must be readable without you scanning through all modules that are pulled in by inheritage until you have the whole plate of spaghetti on your table. And while abstraction is highly dangerous on that layer (2) it is needed on layer (3). I say take a look at LuaJIT that stuff is fast and it is connecting with C in a perfect way. I believe that teamwork between languages is much more powerful than one big chunk of hunk like C++. Symbiosis is better than a parasite. And C++ is a parasite you as a C coder know that C++ is infiltrating your codebase and undermining it taking one routine after an other but giving you nothing back that you can use. Parasites evolutionary seen are a very successful species. C++ is very successful. Still I hate them. Instead I prefer cooperation. Take a look at Lua. You can access everything Lua does from C and you can access vice versa everything C does from Lua. It gives you the flexibility that C++ has not but also the advantages of abstraction without putting some dogma on you. You are doing OOP and abstraction by putting a layer on top of your C basement. Not C with classes like C++ but classes on top of C. No mixing of layers. No fucking ideology corrupting C. Lua is simple. 21 keywords even ANSI-C has 32. So it should be no problem for you to learn that. There is just one higher data that Lua knows the table. You will like that it a mix of array set hashtable depending how you are using that table. I mean Lua is done in C it is near C as near as a language cane but it keeps this is important it keeps linguistic distance to C and goes that English language way that a HLL should. You never will mix up the languages in your mind. You can keep them separated not like with C++ that when working with that for a year your C code starts to look like crap even if you try to write clean C. C++ corrupts Lua does not. It knows it place. It is friendly to C and isn invading the holy and critical implementation layer with obscure HLL crap. LuaJIT is amazingly fast. Here you see how I had to struggle to catch up with C until I managed to safe the honor of our language not without getting a lot of respect for Lua Is there a coding function or simple code to determine if a number is a power of two? answer aid 6651249 So. The correct way to answer your question would be to learn tobine the two languages. Here I show you how easy it is to include Lua into your C program and what excellent kind of teamwork evolves from that Is writing optimized C functions to call from Python worth in terms of performance? If so in what cases? answer aid 6737633 Tobine C & Lua is likebining of static HTML and PHP in 1995. It opens a real new world for your applications the world of App 2. And that is powerful beyond your imagination. To include that into your application is two lines of code. Less than 1 kb of additional program size less than 4 kb of a single system shared library. Lua is faster than many C++ applications and where it is not you can make it with C. Ites with no OOP. Yes. Luaes with no OOP italic dogma. You have to activate it that done over a metaclass of your table shown in every tutorial just two lines of code. Tables can be made classes in every aspect. You will like that. And before I teach you how to do that in C alone please consider this. OOP has no place on the implementation layer that a thing for layer (1). So move that out of your C code base donpromise your C. Stick to data abstraction like with FILE don include OOP dogma on your implementation. It has no place there. That a thing for scripts and application where you can write that stuff also faster. Hope I could help. Tutorialspoint Lua Tutorial
If Linux is free, more secure, stable, and flexible than Windows, then what is/are preventing Linux from being more popular?
The main reason Linux isn as popular as Windows as a desktop client OS is very simple but that answer doesn answer *your* question Im the CEO and Chief Information Officer for a very tech-heavy accounting firm. I will happily agree that the Linux kernel has traditionally been more secure than Microsoft counterpart and that one very valuable aspect of the traditional GNU distribution is its ability to update without a system reboot. HOWEVER after using Linux exclusively for over 2 years being a member of the FSF and a firm adherent to the teachings of Richard Stallman and his ilk Imitted the mortal sin of switching to Windows and declaring my support for the entire Microsoft 365 ecosystem. italic Here what up I run a successful business and having software that literally anyone can easily collaborate on is essential in today marketplace. That isn Linux. Sorry. I still have my Powershell set up so I can use BASHmands and I absolutely love the *idea* of Linux and UNIX but unless were building a server that no mere mortal will interact with it doesn bring the value that Windows does in the market. Im not saying anything bad about Linux I think it absolutely incredible that a crowdsourced *class* of operating systems canpete with corporate counterparts. It truly astounding and awe-inspiring. On the other hand Windows (and Microsoft generally) is a great example of how a capitalist market will find the greatest overall value and beat out even widely available free products italic in their ability to respond more effectively to consumer demand than any other system. Remember that when you vote (and remember UPS and FedEx vs. USPS or the way the city plows your street vs the guy you hire to plow your parking lot). If Linux has taught me anything it the value of finding a way to pay for what I need. The cost is initially daunting but the value far exceeds the price paid.
How do I install Microsoft Office on Ubuntu?
Thanks for the A2A. For your information Ive downvoted and reported this question. No offense. But your mistake is not that you don know how to do it. You mistake is that you don embrace Linux but instead try to turn Linux into Windows. The words MICROSOFT vs. LINUX alone should give you a clue that what you are trying to aplish is counterproductive! Microsoft Office is not meant to be used on Linux. It meant to be used with MICOROSOFT own operating system. Which is WINDOWS! Or would you use a Samsung suite with an iPhone or iTunes with a Samsung smartphone? Didn think so. So why are you trying to install Microsoft Office on Linux? That doesn make sense! Also there is no need to use it with Linux. Because Linux offers TONS of other options like LibreOffice or Apache Office and many more. And tons of alternatives for different purposes. Like Scribus for desktop publishing. Which btw is also available on Windows. Or Krita for drawing and basic s? Writing letters? NO! IT IS NOT! This is typical beginners behavior. You don use the one you know just because you know it. It not the easiest way just because you know it already. Sometimes actually taking the time to learn the new thing is the shorter way than using the wrong thing long-term and wasting time continously just because you don want to invest a bit of time to learn something new. Understand that Linux offers you a lot of freedom if you embrace Linux for what it is. The whole point of Linux is that it offers a modular system that can be quite easily adjusted to your own purpose and taste. Unlike Windows or MacOS Linux is an operating system that can be tailored around your own working style instead of adjusting your working style to what you get. BUT and that a big BUT the one thing Linux always asks is genuine interest and the investment of your own time to learn to actually use it and do it. If you don want that and instead want something that does the job for you with the least interaction on your part then go back to Windows. No offense. But if that is the case Linux is obviously not the operating system for you. EDIT I just saw yourment that you don want people to mention PlayOnLinux or Wine. Well here is a secret Microsoft Office is not a Linux application and therefore won work without the Windows system calls. That what wine does. It mimics the Windows system calls. Meaning without wine you can only go for alternatives. There is no other option! You can just install a Windows application on Linux straight forwards. That doesn work.
What are the free (or close to free) resources for entrepreneurs?
As a blogger and someone who has helped apany sell over 3 units on Amazon I spend a lot of time researching and learning. Some of that learning is about marketing some is about trends and a lot is about reading how other people did it so I can take the parts of what worked for them and incorporate them into my plan. With that being said my number one resource by far are books. Sure they aren free but for a $1 investment that allows you to peak into the mind of an extremely successful person it should be a no brainer. However there are a couple other resources I use regularly that help in either learning about business or in building your own. horizontal-rule 1. Newsletters Nowadays our emails are full of spam but I purposely subscribe to two newsletters that offer a lot of value for me. Prsuit - Prsuit is a daily newsletter for entrepreneurs and others looking for tips about building side hustles changing your mindset and seeing how other people built their success . They have a lighthearted vibe that still gets down to business by ing to a lot of awesome content. I don open many emails but Im always waiting for my email from Prsuit . Ramit Sethi s - While his website title of I Will Teach You To Be Rich is cheesy Ramit and his team are one of the best. Ramit offers several very expensive online courses but I subscribe to his email list for two reasons. First the real reason I subscribe to his list is to study italic his emails. When ites to email marketing and writing copy he is the best. Second many of his emails offer great advice about person finances productivity and life. His site offers free tools and many articles that are extremely helpful. He will try to sell you one of his courses at some point but I just love studying how he goes about the process. horizontal-rule 2. Market Research and Trends Anyone trying to start a website or business needs to be keeping up with what their market is doing. Google trends s - Google trends is a free resource that allows you to see how frequently certain phrases are searched online. This gives you a feel for how certain markets or trends are either growing or dying. You can filter your search by category as well as by country and time frame. I use this almost daily topare trends against each other. Similar Web s - Similar web is a site that allows you to get an estimate of the traffic that other websites get. It shows you an estimate of a couple months of website traffic as well as a breakdown of the main sources for that traffic (search social media email direct etc). This is a great free tool to get an idea of how other websites are doing and where they are getting their traffic from. horizontal-rule 3. Email Opt-In If you have a website you need tools to get subscribers and leads. Sumome s - Sumome is a free tool (with paid options that I don use) that allows you to put opt-in boxes on your website. They offer very customizable forms that you can design to fit in with your brand . You can pick between pop up forms scroll boxes smart bars and a number of other s. You can also choose when to show the opt-in box and on what pages on your site you want it. Designing a cool lead generation for with SumoMe is very simple. MailChimp s - In my opinion SumoMe and MailChimp are the perfect one-two punch for email marketing. SumoMe is the best for getting subscribers and MailChimp is the best at letting you send emails to them. With MailChimp you can send fully customizable automated and manual emails to your list. The free version allows you to have up to 2 subscribers and send several thousand emails per month which is more than enough for someone just getting started. horizontal-rule These are a snapshot into some of the behind the scenes resources I use on a daily basis to learn and research what is working. I hope it helped! Comment which ones you like as well. #OneBrickADay
