    Fixing boot time depends on two factors you wish to deal with: either hardware or software.

    For software : My personal opinion is that if you are not into purely technical terms then it does not make such a big difference in boot time for you to notice significantly ( at most 3-4 secs ), so it is relatively safer to leave it as it is.

    Still if you are compelled to do it then try removing as many startup programs as possible ( ctrl+shift+esc> Start-up ; disable the options which you recognize as useless and google the others. )

    For hardware : (If you can) then upgrade your system (RAM and Processor). It works wonders in reducing boot time.

    Moreover you can also try a clean installation of windows.

    1. Retrieving Saved Wifi Password on Android


    This simple and straight forward process will help you find your saved Wi-Fi passwords on your Android phone. Even better, doing so doesn’t require you to “root” or “jailbreak” the phone.

    1. Open up your File Manager in Android. If you don’t have one built-in, there are a number of free and cheap apps you can download from Google Play. The Root Explorer, OI File Manager, and ES File Explorer are all good options if you need one.
    2. Navigate to the /data/wifi/ or to the/data/misc/wifi/ directory, depending on the device.
    3. In /data/wifi/, look for and open a file namedbcm_supp.conf. In /data/misc/wifi/ look for and open a file named wpa_suppliciant.conf.
    4. After you select wpa_supplicant.conf, you will be prompted to choose a text editor with which to open the file. If you don’t have one built into your Android device, there are a number of free text editor apps you can download from Google Play. 920 Text Editor is a good, free one to use.
    5. Once the file is open, you will be able to see a lot of the data and passwords about the various Wi-Fi networks you’ve previously connected to. Look for the following sequence of code in order to find the password for each Wi-Fi network.

    Simply look for the sequence of code that has the name of the Wi-Fi network whose password you’re looking for.
    network={
    ssid=”NETWORK_NAME_HERE”
    psk=”PASSWORD_HERE”
    key_mgmt=WPA-PSK
    priority=1
    }

    Once you’re in the right file, you can easily locate the saved Wi-Fi passwords and will be in a position to access the network regardless of the time of day and without bothering your co-workers or friends for the password. This easy set of instructions for how to recover Wi-Fi password on Android without root will prove invaluable.

     

    2.

    Just open your browser and type in
    192.168.1.1

    Then use this:
    Id: admin
    Password: admin

    After this just locate the security settings tab, open it and change/view the password.

    There are a lot of online and offline tools for that. My personal favorite is the Google Chrome extension: Awesome Screenshot: Screen capture, Annotate

    Or go to Awesome screenshot (available on all top web browsers).

    As you know RAM is temporary storage. When you are running windows it wil take some space on RAM, and there some softwares or application that by default run in background which they take some space too. And any open programs will take some space in RAM too.

    So by closing unused programs you will free up some space of RAM, by closing background applications using Task Manager which can be opened by holding ctrl+alt+delete all together you free up some other spaces.

    And you can find third party applications to do that for you.

    I am assuming that you are asking with respect to Windows. The supporting screenshots are from Windows 10.

    • Search for Snipping Tools in Programs
    • Snipping tools will thus open.
    • There are four options in Mode: Free Form snip, Rectangular snip, Window snip and Full Screen snip.
    • When in Free form or Rectangular mode, click New to take the snap of the required part of the screen.
    • When in Window mode, you will be asked for the required window whose snap you want to take.
    • When in Full Screen mode, the snap of entire desktop will be taken.
    • Using Delay option you can delay the timer according to your needs.

      Hope this helps.

    1. Java is extremely versatile and used practically everywhere; JavaScript is primarily used for front-end web development with some traction server-side (Node), mobile-side (React Native), and desktop-side (Electron).
    2. Java was a well-designed language; JavaScript was designed in only 10 days and it shows. The latest ECMAScript is pretty much about putting lipstick on a pig.
    3. Java is heavily object-oriented; JavaScript is mostly procedural with some support for object-oriented and functional programming.
    4. Java uses class-based inheritance; JavaScript uses prototypal inheritance. JavaScript “OOP” is prototype-based.
    5. JavaScript has better support for lambdas.
    6. Java is statically and strongly typed; JavaScript is dynamically and weakly typed (allowing for all manner of crazy-ass coercions).
    7. Java has block-level scoping; JavaScript has function-level scoping.
    8. Java has mandatory statement terminators; in JavaScript, they’re optional which can lead to comical situations.
    9. Java executes bytecode in a language virtual machine; JavaScript is essentially interpreted (and JIT’d) in the so-called JavaScript engine.
    10. Java is backed by the Oracle Corporation (and previously by Sun Microsystems); JavaScript has no corporate sponsorship.
    11. There are far more job opportunities for Java than for JavaScript. According to Indeed.com, in the United States at the time of writing, Java has 66,633 job postings, whereas JavaScript has 37,110. Java is better for your career.

    Java and JavaScript share only two qualities:

    • they both have largely C-like syntax
    • they have the first four characters of their names in common

    Otherwise, they are completely different languages.

  • Asked on April 1, 2020 in Programmer.

    I will go ahead and disagree with the majority of answers here:

    1. Choice of languages matter a lot!
      1. Caveat: except for personal projects and toys.
    2. Java is hands down better than Python.
      1. Caveat 1: Java’s advantages (will explain later) increase with difficulty of the requirements, so toy websites are indeed easier to do in Python. However, in that case, writing a static generator (in Python) is probably easiest.
      2. Caveat 2: There are specific cases where Python is better. If you are (or member of a teams who are) one of these Python wizards, well….. Plus, very simple, straight-forward websites can be done easier with Python. However, in about 90% of the time, Java wins.

    Let me go over the points one at a time.

    I) It is important to choose correct language

    Let me share with you 2 anecdotes:

    1. At work, I have seen a variety of languages employed. Without fail, Java (or C#, or one of those “serious programming languages”) projects are the best written, with the highest code coverage, with the most stability. Without fail. Ruby looks good until the 3rd person starts to work on the same project. Don’t get me started on LISP (can be very nice, but extremely hard to get it correctly).
    2. Within the last 4 years, my most enjoyable programming experience involves (re-)implementation of a bunch of machine learning algorithms in Scheme. I felt so alive after the weekend of dreaming up beautiful structures.

    My point is, the language choice dictates much much more than we give credit for. To be 150% fair, the features of the language itself generally speaking are not the only deciding factor. However, the mere presence of a language tends to make or break code quality.

    In conclusion:

    • Business-wise: choosing the right language usually save time, money, and a lot of trouble.
    • Personal-wise:
      • Right language makes your time much more enjoyable.
      • New & correct language reforms your brain and optimizes it.

    Therefore, choose wisely!

    II) Java wins, hands down

    Here are the advantages of Java:

    • Professionalism (probably more relevant in business setting)
      Using Java (& other “professional languages” like C#) feels similar to going to the library or wearing a pressed shirt. When you are in the library, no one forces you to read books or be prim and proper, but the feel of the place makes you want to do the above. Similarly, when I wear a pressed shirt, I can slouch; the shirt would rub against my back and shoulders, reminding me that it would much prefer to stay in shape.
      Java gives off such feeling. It feels so boring, so unexciting that hacks and clever tricks look stupidly out of place. It makes you want to write the kind of code that would fade in the background, but would rarely cause issues. Interestingly enough, this is the best kind of code.
      This way, code in Java tends to gravitate away from downright terrible. At worse, they look boring and tedious. However, I would take boring and tedious over crazy jackshit any day of the week.
    • Availability of Expertise:
      No one should be surprised if Java has the most expertise around. This in term of available developers as well as available code snippets to learn from. Given that we usually learn by examples, these resources and expertise are invaluable.
      Furthermore, Java tends not to inspire holy war and works extremely hard to avoid opinions. Python, perl, Ruby, LISP (actually, each different flavors of LISP), Haskell, etc. have very strong and colorful characters. Java does not have such personality. Which may make it boring, but, again, only rarely do holy wars break out over Java. This tends to allow programmers to work together and learn from each other much better.
    • Tooling:
      You can argue until your face is blue, but one thing is certain: as a programming language, Java has the best tooling. It has at least 3 outstanding IDEs (Eclipse, Netbeans, and IntelliJ), along with mirage of smaller systems. Each of these, then, have lots of plug-ins, which pretty much cover just about any situations you can find yourself in.
    • Type system: OOP and static
      OOP excels in description of a system. It’s very good at saying “what”. Procedural and functional are better at saying “how,” but OOP describes “what” much better. This makes OOP describes long-running systems better. Functional & procedural talking about 1 task, which, but definition, has a start and an end. OOP talks about system description, which has neither start nor end.
      As such OOP describes website well. A website has neither start nor end. It just is, responding to users’ requests. It fits very well with OOP. And Java is OOP. Not the most OOP, mind you, but it is OO enough to make things pleasant. It’s certainly more OO than Python.
      Java is also statically typed, which is such a pleasant things to work with. Especially for larger systems that have tight coupling with its infrastructure (eg. your website!). Since the types a known at compiled (read: coding) time, your IDE can chase down all references and help you deciding what needs to go where. Python’s (or perl’s and Scheme’s; the other 2 are among my favorites) type system gets extremely hard to deal with as the size of the project increases.
      Note that this is more than mere “bug prevention.” It’s more pleasant to code in, too! Types usually describe the intention of the functions. Plus, you can easily navigate to declarations and implementations of whatever you need, which makes coding so much easier.
    • JVM platform: stability in presence & future proof
      Python as a platform sucks compared to JVM. Frankly, anything-as-a-platform (except maybe Linux or unix) pales in comparison to JVM. Even .NET is not quite 100% JVM.
      See, JVM offers you roughly 2 major advantages.
      First, it highly prioritizes backward-compatibility. Only extremely rarely do you have issue with upgrading JVM. This reflects both advantages in compiling down to simpler system (bytecodes are easier to maintain backward-compatibility than fullblown languages) and priorities of Java as a project and community.
      Secondly, it supports myriad of other languages. You can have Scala, Groovy, Scheme (Kawa, thou art my love), etc. run side-by-side! Doing the same thing in Python requires a lot of finesse, if possible at all, and a lot of risk and performance penalty. Thus, when you choose Java, you are not locked out of other paradigm that Java as a language does not support well. When you choose Python, you’d better be sure that you are really into Python.
    • Performance: Without further elaboration, JVM is faster than Python. End of discussion.
    • Libraries and support:
      Due to its longevity and status, Java enjoys enormous sets of 3rd party libraries. Its libraries are also much better support and written, compared to CPAN and Python’s repo.
      Java also enjoys supports on many more platforms: AWS Lambda to Google cloud to plain Linux.
    • Economics:
      One point to make clear: if you like to have fun, Python may be a good language (but how fun in Python? You can also have fun with Javascript and LISP and Haskell and perl). However, economically speaking, Java enjoys much more powerful network effects.
      More job posting is in Java. Reversely, more qualified candidates can work in Java. Better yet, due to Java nature (see above about holy wars), Java can be picked up much faster. Due to its conservative attitude, newbies in Java will pose smaller risks.

    Conclusion: do it in Java. Stay away from Python. Pythons are good for decoration and roasting (and scaring your siblings :P). I don’t find it to be a good computer tool.

    C runs the world and runs Answerki. C is my favorite language of all time.

    I know I may get flak for saying this: but I think C is a lot better than Python.

    why?

    1. with C you can develop operating systems and manipulate memory directly. in python I have never heard of a OS written in it
    2. C is a Systems language, while python is a scripting language. C is a lot more powerful than python, as python was designed as teaching language(kinda like pascal)
    3. You can literally do anything with C. BIOSes, OSes, apps, games, servers, etc are all written in C. hell even the scripting languages such as python, perl, ruby, php and javascript all have interpreters written in C.
    4. C is the grand father of the modern programming language. without C there wouldn’t be Java, Javascript, C#, C++, Lua, Python, Ruby, Rust.
    5. C is very versatile(kind of ties in with reason 3)
    6. finally C allows you to get to the metal(i.e the hardware) more so than the other languages. please consider this chart below

    there is no “bad” programming language, all languages are pretty much same except in syntax and how close they get to the metal.
