2. Check out their hands – intelligent people have nimble fingers and are often graceful in their movements

3. Notice how they dress – intelligent people generally have a good sense of style and know what looks good on them

4. Listen to the way they speak – intelligent people are usually articulate and well-spoken

5. Watch their body language – intelligent people tend to be confident in their movements and gestures

8. People who are interested in learning new things and have a diverse range of interests

9. Pay attention to the way someone speaks – intelligent people tend to be articulate and well-spoken

10. Watch for people who are good at problem-solving and can think on their feet

11. Notice if someone is always surrounded by friends or colleagues – intelligent people often have a large social circle

13. Highly intelligent people  are very aware of the vast number of things they don’t know, and are somewhat humble and open-minded.

14. Highly intelligent people learn from others across a wide range of topics.

15. Highly intelligent people don’t talk about their IQ and Intelligence, and are keenly aware that there are many other things important in life.

16. Highly intelligent people Know quite a bit about many different topics, and can often explain even complex topics in ways simple enough for the listener to grasp.

17. Highly intelligent people tend to ask very thought provoking questions they don’t know the answers to. (This last characteristic is the hallmark of some of the brightest people I know, and makes them fascinating and thought-provoking conversationalists).

According to Matthew Cooper, here are some low-key signs of highly intelligent people:

1. Most of them have the habit of staying up late into the night.

2. They may have bad handwriting because of the trouble with their mouth and hand keeping up.

3. They have unusual, out of the box, apparently ‘crazy’ ideas.

4. They’re prefer to be with their own company.

5. They’re brutally honest with what they don’t know.

8. They have good body memory. Their bodies can pick up routines faster than others.

9. They use the Keanu behavior to boost intelligence.

Keanu Reeves says highly intelligent people play a game. They try to be wrong once in a while. They practice being wrong more often to reset their egos.

10. They can explain difficult matter in an easy way.

11. They can make connections between seemingly unrelated subjects.

Research has shown that words account for only 7 percent of how we communicate whereas our body language (55 percent) and voice tone (30 percent) represent the rest. Our entire body language can be read and interpreted. Almost our every external body part and its position speaks lots and lots, not vocally but via body language which also keeps altering with respect to the circumstances, our feelings or people around. Here, we are going to deal with the psychological tricks to read other people’s face. You just need to remember…Your emotions get etched on your face.

What are the best psychological tricks to read other’s face?

I believe that smart people have hunter-gatherer minds (intuitives in Myers-Briggs), whereas most people have farmer minds and these two are often not very compatible.

Hunter-gatherer people often become deeply introverted in childhood already, because they understand that they are different from the vast majority of people (INs only make up about 10% of the population) and when they grow up they feel they are misunderstood and that they can’t make a change anyway.

Read “The Little Prince” and you get an idea what it is like for a gifted kid to grow up: you see the elephant inside the boa where others see a hat (NB: this is a metaphor):

“Whenever I encountered a grown-up who seemed to be intelligent, I would experiment on him with my drawing Number One, which I have always kept. I wanted to see if he really understood anything.

But he would always answer, “That’s a hat.” … So I lived by myself, with no one to talk to”

Antoine de Saint-Exupéry (INFP)

So, what is the point of talking about something other people can’t see??? 90% of the time we would be wasting our energy and that is why we keep quiet. People would think we are crazy.

No, external factors are not indicators of intelligence. They can often give off an impression of a certain level of intelligence, whether high or low, but you need to actually see them use their head to know how capable they are mentally.

Yes. Top 2%er IQ wise here.

But, and this is important- IQ is like the measurements on the outside of the cup, it only shows how full it can be, not how full it is, and most importantly says nothing about what it’s filled with. There were probably more nazis with high IQs than saints.

I can “think about my thinking”, and choose from more options how I want to think about a subject.

I can be wrong in my thinking and change it when provided with a better solution or better data.

I don’t reject uncomfortable truths. I understand there is nothing after death. I wish it was otherwise but can’t ignore the evidence despite humanity’s culturally indoctrinated wishful thinking otherwise.

I see a “big picture”. My definition of “big picture ” means that I’m far enough back that I don’t see “myself” in it. That gives me the ability to see conclusions and concepts that are “outside the box”.

I spot patterns earlier and can separate them from “back ground noise ” and spurious data faster than a lot of people. I’m the one who chooses not to go on the company picnic as the boss always fires someone who went a week later. The boss doesn’t see this pattern, the other workers don’t see the pattern. Everyone else wants to go because of the free booze and sandwiches.

I get bored. Very very bored. Imagine you are 30 and are trapped in a culture determined by the desires and minds of 14 Yr olds. It works great for them, but there’s really not much of interest for you and when you pursue your own interests you are a weirdo iconoclast until they see that your ideas can also be used to make their skateboards go faster and shoot sparks from the trucks… I will probably kill myself once my age makes it too hard to keep myself amused.

I am used to isolation being misunderstood, rejected, and laughed at by those who don’t understand what I’m doing. I am far too used to paranoid managers who realize that they have an employee who is smarter than them. I’m used to.people telling me I’m stupid for wanting to know how something actually works. “Fusion!? Screw that science crap!-the sun is hot because its burning. Stop over thinking stupid!”

I am used to Dr’s and professionals in other fields stopping and looking at me funny when I start discussing the finer points of insulin transport through a cell wall, finer points of nuerochemistry, or other specialist knowledge. It’s taken me years to find doctors I can work with. They are too used to bozos coming in with “but I saw it on the Internet “.

I’m a prodigy burn out, one of the last “educated bums”. Eight years in university, a string of letters behind my name and my diplomas are stacked up, face downin my back porch. My last job before retirement was as a clerk in a legal late night cannabis dispensary in the inner city. My job before that was as an Education and Programming Director at a major art gallery.

I don’t chase after money for money’s sake. Lots of people think I am stupid for not maxing out my career potential, but I get bored with the work, the people and the collateral issues of having to work. So I opted for self sufficiency and an urban peasant lifestyle. I have enough money to see me through to “the end”, and to provide an estate for my daughters. I am bi no means poor, but manage and use money as a tool rather than a fetish.

I am extremely hard to live with. I’m a bit of a slob (organized neatness is a compulsive trait of those who can not remember where everything is), pedantic and often disinterested in things that seem very important (fashion, morality, celebrities, ie). I have been in five serious relationships, and happily bought people houses to get out of them.

I hope this helps, but one thing you are going to find with very high intelligence is that those with it often have frustrating, broken and dysfunctional lives. Each response is going to vary wildly.

To sum it up….

A friend who truly knows me put it like this: “Dustin, you have a mind like a finely tuned sports car, with a 700 hp engine. You live in a world built for tricycles. Have a beer!”

I have a Mensa level IQ. My husband’s was probably around 110 -120. I don’t know for sure because if he ever took an IQ test, he never told me. I know I could grasp higher math and science more than he could.

That said, we loved one another and supported one another through 47 years of marriage. We respected one another. We laughed together. We cried together.

If he didn’t understand something, I explained it until he could. He taught me to drive. We never treated the other as though one was less than the other.

He had more life experience than I as he was 20 years my senior. School was easy for me. He never had much use for formal education until he met me. I supported him in his interests and his desire to change jobs often. He supported me when I went back to school when I was forty. He listened while I told him the exciting new things I was learning even when he wasn’t really interested.

I supported him when he retired and I watched him learn to drive both a bus and a fire truck when he was sixty- five. He learned to parallel park both of them.

He once asked me why I was with someone so less intelligent than I was. I told him I wasn’t. There are more kinds of intelligence than that measured by IQ tests.

Respect, laughter, and love go a long way in leveling any differences two people have. So yes, a relationship can work even if one of the people has a higher IQ than the other.

He passed away a year and a half ago. I miss him acutely.

I- Networking:

  1. How many bytes are there in a MAC address?
    MAC, Media Access Control, address is a globally unique identifier assigned to network devices, and therefore it is often referred to as hardware or physical address. MAC addresses are 6-byte (48-bits) in length, and are written in MM:MM:MM:SS:SS:SS format.
  2. What are the different parts of a TCP packet?
    The term TCP packet appears in both informal and formal usage, whereas in more precise terminology segment refers to the TCP protocol data unit (PDU), datagram to the IP PDU, and frame to the data link layer PDU: … A TCP segment consists of a segment header and a data section.
  3. Networking: Which command is used to initialize an interface, assign IP address, etc.
    ifconfig (interface configuration). The equivalent command for Dos is ipconfig.
    Other useful networking commands are: Ping, traceroute, netstat, dig, nslookup, route, lsof
  4. What’s the difference between TCP and UDP; Between DNS TCP and UDP?
    There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol.
    The reality is that DNS queries can also use TCP port 53 if UDP port 53 is not accepted.
    DNS uses TCP for Zone Transfer over port :53.
    DNS uses UDP for DNS Queries over port :53.

  5. What are defaults ports used by http, telnet, ftp, smtp, dns, , snmp, squid?
    All those services are part of the Application level of the TCP/IP protocol.
    http => 80
    telnet => 23
    ftp => 20 (data transfer), 21 (Connection established)
    smtp => 25
    dns => 53
    snmp => 161
    dhcp => 67 (server), 68 (Client)
    ssh => 22
    squid => 3128
  6. How many host available in a subnet (Class B and C Networks)
  7. How DNS works?
    When you enter a URL into your Web browser, your DNS server uses its resources to resolve the name into the IP address for the appropriate Web server.
  8. What is the difference between class A, class B and class C IP addresses?
    Class A Network (/ 8 Prefixes)
    This network is 8-bit network prefix. IP address range from to
    Class B Networks (/16 Prefixes)
    This network is 16-bit network prefix. IP address range from to C Networks (/24 Prefixes)
    This network is 24-bit network prefix.IP address range from to
  9. Difference between ospf and bgp?
    The first reason is that BGP is more scalable than OSPF. , and this, normal igp like ospf cannot perform. Generally speaking OSPF and BGP are routing protocols for two different things. OSPF is an IGP (Interior Gateway Protocol) and is used internally within a companies network to provide routing.

II- Operating System
1&1 Web Hosting

  1. How to find the Operating System version?
    $uname -a
    To check the distribution for redhat for example: $cat /etc/redhat –release
  2. How to list all the process running?
    To list java processes, ps -ef | grep java
    To list processes on a specific port:
    netstat -aon | findstr :port_number
    lsof -i:80
  3. How to check disk space?
    df shows the amount of disk space used and available.
    du displays the amount of disk used by the specified files and for each subdirectories.
    To drill down and find out which file is filling up a drive: du -ks /drive_name/* | sort -nr | head
  4. How to check memory usage?
    free or cat /proc/meminfo
  5. What is the load average?
    It is the average sum of the number of process waiting in the queue and the number of process currently executing over the period of 1, 5 and 15 minutes. Use top to find the load average.
  6. What is a load balancer?
    A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications.
  7. What is the Linux Kernel?
    The Linux Kernel is a low-level systems software whose main role is to manage hardware resources for the user. It is also used to provide an interface for user-level interaction.
  8. What is the default kill signal?
    There are many different signals that can be sent (see signal for a full list), although the signals in which users are generally most interested are SIGTERM (“terminate”) and SIGKILL (“kill”). The default signal sent is SIGTERM.
    kill 1234
    kill -s TERM 1234
    kill -TERM 1234
    kill -15 1234
  9. Describe Linux boot process
    As power comes up, the BIOS (Basic Input/Output System) is given control and executes MBR (Master Boot Record). The MBR executes GRUB (Grand Unified Boot Loader). GRUB executes Kernel. Kernel executes /sbin/init. Init executes run level programs. Run level programs are executed from /etc/rc.d/rc*.d
    Mac OS X Boot Process:

    Boot ROM Firmware. Part of Hardware system
    BootROM firmware is activated
    POST Power-On Self Test
    initializes some hardware interfaces and verifies that sufficient memory is available and in a good state.
    EFI Extensible Firmware Interface
    EFI does basic hardware initialization and selects which operating system to use.
    BOOTX boot.efi boot loader
    load the kernel environment
    Rooting/Kernel The init routine of the kernel is executed
    boot loader starts the kernel’s initialization procedure
    Various Mach/BSD data structures are initialized by the kernel.
    The I/O Kit is initialized.
    The kernel starts /sbin/mach_init
    Run Level mach_init starts /sbin/init
    init determines the runlevel, and runs /etc/rc.boot, which sets up the machine enough to run single-user.
    rc.boot figures out the type of boot (Multi-User, Safe, CD-ROM, Network etc.)
  10. List services enabled at a particular run level
    chkconfig –list | grep 5:0n
    Enable|Disable a service at a specific run level: chkconfig on|off –level 5
  11. How do you stop a bash fork bomb?
    Create a fork bomb by editing limits.conf:
    root hard nproc 512
    Drop a fork bomb as below:
    :(){ :|:& };:
    Assuming you have access to shell:
    kill -STOP
    killall -STOP -u user1
    killall -KILL -u user1
  12. What is a fork?
    fork is an operation whereby a process creates a copy of itself. It is usually a system call, implemented in the kernel. Fork is the primary (and historically, only) method of process creation on Unix-like operating systems.
  13. What is the D state?
    D state code means that process is in uninterruptible sleep, and that may mean different things but it is usually I/O.

III- File System

  1. What is umask?
    umask is “User File Creation Mask”, which determines the settings of a mask that controls which file permissions are set for files and directories when they are created.
  2. What is the role of the swap space?
    A swap space is a certain amount of space used by Linux to temporarily hold some programs that are running concurrently. This happens when RAM does not have enough memory to hold all programs that are executing.
  • What is the role of the swap space?
    A swap space is a certain amount of space used by Linux to temporarily hold some programs that are running concurrently. This happens when RAM does not have enough memory to hold all programs that are executing.
  • What is the null device in Linux?
    The null device is typically used for disposing of unwanted output streams of a process, or as a convenient empty file for input streams. This is usually done by redirection. The /dev/null device is a special file, not a directory, so one cannot move a whole file or directory into it with the Unix mv command.You might receive the “Bad file descriptor” error message if /dev/null has been deleted or overwritten. You can infer this cause when file system is reported as read-only at the time of booting through error messages, such as“/dev/null: Read-only filesystem” and “dup2: bad file descriptor”.
    In Unix and related computer operating systems, a file descriptor (FD, less frequently fildes) is an abstract indicator (handle) used to access a file or other input/output resource, such as a pipe or network socket.
  • What is a inode?
    The inode is a data structure in a Unix-style file system that describes a filesystem object such as a file or a directory. Each inode stores the attributes and disk block location(s) of the object’s data.

IV- Databases

  1. What is the difference between a document store and a relational database?
    In a relational database system you must define a schema before adding records to a database. The schema is the structure described in a formal language supported by the database and provides a blueprint for the tables in a database and the relationships between tables of data. Within a table, you need to define constraints in terms of rows and named columns as well as the type of data that can be stored in each column.In contrast, a document-oriented database contains documents, which are records that describe the data in the document, as well as the actual data. Documents can be as complex as you choose; you can use nested data to provide additional sub-categories of information about your object. You can also use one or more document to represent a real-world object.
  2. How to optimise a slow DB?
    • Rewrite the queries
    • Change indexing strategy
    • Change schema
    • Use an external cache
    • Server tuning and beyond
  3. How would you build a 1 Petabyte storage with commodity hardware?
    Using JBODs with large capacity disks with Linux in a distributed storage system stacking nodes until 1PB is reached.
    JBOD (which stands for “just a bunch of disks”) generally refers to a collection of hard disks that have not been configured to act as a redundant array of independent disks (RAID) array.

V- Scripting

  1. What is @INC in Perl?
    The @INC Array. @INC is a special Perl variable that is the equivalent to the shell’s PATH variable. Whereas PATH contains a list of directories to search for executables, @INC contains a list of directories from which Perl modules and libraries can be loaded.
  2. Strings comparison – operator – for loop – if statement
  3. Sort access log file by http Response Codes
    Via Shell using linux commands
    cat sample_log.log | cut -d ‘”‘ -f3 | cut -d ‘ ‘ -f2 | sort | uniq -c | sort -rn
  4. Sort access log file by http Response Codes Using awk
    awk ‘{print $9}’ sample_log.log | sort | uniq -c | sort -rn
  5. Find broken links from access log file
    awk ‘($9 ~ /404/)’ sample_log.log | awk ‘{print $7}’ sample_log.log | sort | uniq -c | sort -rn
  6. Most requested page:
    awk -F\” ‘{print $2}’ sample_log.log | awk ‘{print $2}’ | sort | uniq -c | sort -r
  7. Count all occurrences of a word in a file
    grep -o “user” sample_log.log | wc -w
