What are the most difficult things people have to learn in their 20s?


Answer by Rich Tatum:

Here are some things I really, really wish I knew when I was twenty.

  • Love hurts, but not as much as not loving.
  • The friendships you nurture will have a greater effect on your life than where you work or what you earn.
  • You are not your job. You are not your bankroll. You are not the sum of your possessions.
  • The company does not love you. It has no heart. You are replaceable. Keep your parachute handy.
  • Few decisions will ever shape your future life more than who you choose to marry. To marry well, you must choose well.
  • Love is a commitment.
  • Your passions will grow out of your values. Make early, wise choices to value what (and who) is good, trustworthy, and praiseworthy.
  • Integrity preserved is honor won.
  • Rejoice in your health. It fades fast.
  • Find a passion. Pick a hobby, own it: photography, juggling—whatever. Get your 10K hours of perfect practice in early and change your life.
  • Don’t bother comparing yourself to others—this only leads to heartbreak, anger, and disappointment.
  • Most disappointments arise from unmet expectations. Set realistic expectations for yourself, based on your strengths, then strive to exceed them.
  • Don’t drive others to meet expectations they’ve committed to — lead, inspire, and help them do it.
  • Don’t set expectations for others when they have not or cannot commit to them.
  • Expectations you never communicate and negotiate will rarely be met—except by accident.
  • Don’t complain. Either change your situation, learn to cope, or change perspective.
  • Don’t worry about getting a big salary in your youth: first learn to execute tasks with skill, excellence, and grace.
  • Little stuff matters—even in lowly jobs. The boss notices—and even if not, your peers and colleagues will.
  • Ultimately, privacy is a myth: God sees everything. The cloud records everything. NSA files everything. So, live transparently and don’t waste useless energy hiding failures.
  • Don’t look down on others because they don’t have what you didn’t earn: your intellect, your beauty, and your culture of birth are undeserved gifts. Stay humble.
  • Failure is an opportunity: no great man or woman ever achieved significance without great failures. Fail forward.
  • Never withhold an apology when it’s merited. Deliver it quickly, sincerely, and personally—before resentment festers.
  • You don’t need to nurture old guilt when you’re forgiven. But remembering the shame can help you avoid repeats.
  • Mere belief in anything signifies little more than assent: trust and behavior reveal where true convictions lie.
  • The main thing you need to do quickly is to stop doing things quickly. Trade hurry for calm, confidence, and precision.
  • Everybody needs an editor. Everybody. Especially editors.
  • Get your work done first so you can play without guilt. Even better, make work play and the fun never ends!
  • If you want to develop your passion and gift, stop worrying about the things you do poorly. Go with your strengths!
  • Avoid fights. Seriously. Avoid them like a plague: nobody wins in a fight, even if you walk away unscathed. But when a fight picks you, leave everything on the mat and give it your all. Hold nothing back.
  • If you’re bored, you’re doing it wrong.
  • The skills that will help your career most are the abilities to assimilate, communicate, and persuade. Keep learning.
  • Nothing in this life—no pain, no agony, no failure—compares to the eternal joy of Heaven. Live in light of eternity.
  • Protect your joy. Nothing is easier to lose by over-thinking, overanalyzing, and second-guessing. On the other hand, always consider the long-term consequences of your choices: stupid decisions made in the moment can rob you of years of joy and happiness.
  • Your purpose in life determines how you frame events. You can maintain your joy in the most dire circumstances if you find meaning for your life. Dig deep.
  • It truly matters what you think about. Think well by reading good books, building good, loving relationships, having good conversation, and imitating great people.

I’m still learning — in fact I haven’t fully appreciated most of the list I made, myself. And I’m still adding to it. But I’m getting better.

Website Hosting also Free Choices

Nowadays I see a lot of folks talking about web hosting. Most of the time, people don’t know that different websites require different solutions and therefore different hosts. They also don’t know the difference between a host and a domain name, and that there are services for each one of those problems. Here I will try to tackle this a little bit and give you a few suggestions.Thus, by the end of this article, you should be able to answer the following questions on your own:

  • What is Web Hosting and Domain Naming?
  • Is a Domain Name absolutely necessary?
  • What are the main difference between Static Web pages and Dynamic We pages?
  • Is my website static or dynamic?
  • What free solution should I pick to host my website?


For the purpose of this article, we will use the following definitions of web hosting and domain naming as follows:

Web Hosting

Consists in hosting and keeping files and data for websites, in machines called servers, that give away part of they available disk space to maintain the data. Web servers also provide internet access, which can be payed separately.

Domain Name

A name owned by a person or a company, made of a string composed by letters, number and special characters, used as an internet address that identifies the location of specific webpages.

So, now that we have these two aspects defined let’s see how they play together. A Web Hosting service, will give you a machine with a connection to the internet, where you can put your website’s data. Because the machine is connected to the internet, everyone can access it’s contents by using the machine’s IP address. However, IP numbers are long sequences, and are also very hard for people to memorize. To fix this problem, the Domain Name System was created. Shortly put, this system maps IP numbers, to website names that you can memorize.

Your needs

So, now that you know that Web Host service will give you a computer (server) to store data, and a Domain Name service will map the server’s IP address into a name that people can memorize, it is time to understand what your web site needs.

To know what your website needs, you must know the type of your website. Websites are made of Web Pages, and there are two main types of these:

  1. Static Web page: Also called flat page/stationary page, this is usually a web page that never changes, and that presents the same content in the same way to all users no matter what. Static Web pages are usually made using only HTML and CSS, and are the easiest to create because they don’t require databases, nor advanced programming skills. Some Static Web Pages can also use javascript and jquery to present content, but there is never the need to store data from the user in any case. To deploy a static Web page, all you need to do is to place your files in a server connected to the internet.
  2. Dynamic Web Page: A dynamic web page is generated in real-time. These pages usually include web scripting code and require access to databases in order to keep and manage information from users or programs. These Web pages usually use frameworks, and languages like Ruby, PHP, Python, Java, Javascript and so on to make the communication with the server’s local database easier.

With this information we can then make the following statement: If a Website contains one or more Dynamic Web pages, it is a dynamic website, otherwise it is a Static Website.

Overall, Static Websites are easier to create, and are ideal for beginners. Dynamic websites, require more knowledge and are harder to create, but they are a lot easier to maintain then static websites due to all the automation they have.
The list of advantages and disadvantages between static and dynamic websites goes longer, but these are the basics you need to know.

Your choices

So, now that you probably know the type of website you are building, it’s time to evaluate the market that exists. The important thing here is the type of Web hosting service that you will need. Some web hosts only allow for static web sites, while others also allow for dynamic.
Domain Name services are independent of your web host, however, sometimes the web host company also provides an integrated web naming service that you can use.

Free Web Hosting for Static Websites:

Free Web Hosting for Dynamic Websites:

All these web hosts will make your webpage available online for everyone for free, however they will create very long and horrible links for your websites. This is where Domain Naming comes in.

Free Domain Naming services:

Using Custom Domain with Google Drive:

Using a Custom Domain with Dropbox:

An alternative to choosing a domain and a name for your website is also URL shortening:

Free URL shorteners services:

For more information about this section, please visit the Sources Section.


By now you should be able to answer the formulated questions presented in the introduction. Web hosts provide servers that can hold your data and are connected to the internet. Domain Names are pretty much “masks” that map IP addresses and other horrible long names into string that people can actually memorize. URL shorteners can therefore be seen as a sort of Domain Naming service, provided of course that you can actually memorize the URL they give you.
Last but not least, the more complex your website is, the more complete the service you rent must be. Dynamic websites many times require complex online platforms such as Heroku or Google Apps to be deployed, and there are many others out there depending on the language set you use.

Finding a computer’s model using command prompt & terminal


May be you want to find out the drivers for your PC and you need to be specific, you have to have the model of your PC. It’s fairly simple.

A. On Windows Command Prompt:

wmic csproduct get name

On my machine that returns two lines, one saying Name and another with my machine’s model name:

Dell Inspiron 15 N5040

Now that’s cool!!

B. For Linux Terminal:

sudo dmidecode | grep -A3 '^System Information'


This is what you get:

To All First Years!!


When we join campus,we get to embrace, wait. We have no choice but to embrace what is happening around us. By that I mean, the Technology bit where you get a whole room of first years with laptops, a sound system and to make it worse, the talk geek. So how do you adapt. Interact with them, they usually don’t bit and they make come out as arrogant but in the long run, if you know how compromise, you will learn a lot.

These are the Tech items you really need in first year:


  1. Flash Disk preferably 8GB and above. Why that big? Yes, we want to also copy movies to watch other than notes and assignments. I don’t encourage you copy your friends’ assignment but if you are referring, that’s fine with me. Please don’t buy cheap fake one.
  2. Smart Phone. When I say smart phone, please don’t assume I mean those china phones with aerials, shiny silver plastic phones with these weird interface that has all in one features. No no. I mean the ones with Big brand names that are common like Samsung, Sony, LG, Nokia, HTC (if you have that much cash) and etc. These phones is like your laptop, in fact it is your laptop! You can do anything with it! Watch Movies, play games (CandyCrush, Flappy Bird), watch movies in the landscape rotation, music, you download stuff and the greatest of all *drum rolls* DO ASSIGNMENTS in it!!!! That I learnt waaay before I got my laptop.
  3. Original USB Cable. If you have the smartphone, use the usb it came with. If you don’t, please don’t steal. It’s quite painful to find an original one. If you don’t have an original, go to a technology shop and buy one. You will always know how to differentiate a fake one.
  4. Phone Memory Card. Again it is same as Flash Disk but very mobile.
  5. Location of Computer Lab. Needless to say, the phone can be annoying and the wireless connection in the school can be down and you need to send an email or check what’s new on facebook. But please NEVER copy anything from the computers in the Computer Lab. NEVER! If you love yourself, leave alone others, don’t even let that thought of transferring data from them cross your mind. Free advice there. 🙂
  6. Laptop. As eager as you are to know what about the laptop am going to write, you will get your answers finally. It all depends with the company you have who will influence you in the choice of laptop you get. Be it friends from home, school, relatives, your boyfriend (a girl can’t influence the choice of a dudes laptop, no offence. UNLESS she’s your big sister.) and lastly for the wise, those who Google the question. For me being a smart guy together with my roommate,we went to inquire from the Chairmain of our Department. For my roommate, he still says he will buy the laptop ( 3 years later!!). Here comes the biggest mistake. Please DON’T forget to mention either to Google or to whoever you are asking for the advice, what you love. For me, am a Gamer and Coder. So I can say I got a laptop that plays low graphics game.
  7. All Wi-fi hotspots. This one is MANDATORY if you know that you have a purpose in life. Who lives without Internet Access?? Who? How do you know? Good question. You will see more than 5 guys on the same space or may be one selfish guy in a certain corner on their laptop who knows that place is a good hotspot and they won’t even sell that secret to anyone. Those will be where you will reside.
  8. A nocturnal body. Universities in Kenya are all the same. Internet is best at the wee hours of the morning. 1Am – 5am. If you need to sleep at that time, good for you. Benefits for the rest of us. I will give you this simple tip I got from the movie Undisputed 3. That reminds me I need to download it. Anyway, the quote goes like this: “Improvise, Adapt, Overcome.” Boyka was being advised by a Black-American Boxer.
  9. An extension Cable. Guys guys! The hotspots have few sockets. Lets share the electricity. Help a brother.
  10. I almost forgot! Headphones!! It won’t cost you more than Ksh.1000. It does two things, keeps you happy when browsing through the internet (music). Two, keeps your personal stuff to yourself. We are not interested in listening to what your listening to. Whether it’s a video or music.

In summary, this is a what I got to learn when I was in first year in Taveta, Kenya. Hope you will learn from all this.
