Why Facebook is full of giraffes

If you've spent any time on Facebook in the past day or so, you may be wondering: What's up with all the giraffes?
Are they suddenly endangered? Is the circus in town? Is Toys R Us having a sale?
No, no and no. (Although depending on where you live, the circus may actually be in town.) Photos of the spindly, long-necked animals are the byproduct of a meme that's been sweeping the social network in recent days.

The meme invites users to share a riddle with their friends, who then are supposed to send a private message with the answer (don't post it in the comments, obviously). Any user who guesses wrong must agree to change his or her profile photo with one of a giraffe.
Why a giraffe? It's not clear.
The riddle goes like this:
3:00 am, the doorbell rings and you wake up. Unexpected visitors. It's your parents and they are there for breakfast. You have strawberry jam, honey, wine, bread and cheese. What is the first thing you open?
(Spoiler alert: The answer is at the bottom of this story.)
Most users agree there are two acceptable answers, although given that Facebook is an unruly community of 1.2 billion people, there's some debate over that.
Judging by some comments on Facebook, some users are growing tired of the giraffe riddle. Others are making jokes.
"If anyone shows up at my house at 3 am they had better get a hotel because I'm not answering the door," wrote one commenter on CNN's Facebook page.
Said another, "I got it right, but the giraffe pic cracked me up so I made it my profile pic."
Then there was this commenter on the Chicago Tribune's Facebook page: "Truth be told ... upon realizing it was your parents you'd probably open the wine first."
The answers: "The door" and "your eyes."

The REAL Answer to the Giraffe Riddle on Facebook

The REAL Answer to the Giraffe Riddle on Facebook - There is a lot of controversy over the true answer to The Great Giraffe Challenge riddle on Facebook. Once and for all, we end this debate with logic and wit to give all the haters the real answer.

The instigator of the viral riddle is New Zealander Andrew Strugnell. While he admits he did not pen the riddle, many people are arguing that they got the riddle correct even though their answer contradicts Strugnell’s. So why is it so difficult to accept Strugnell’s answer?

It’s 3am, the doorbell rings and you wake up. Unexpected visitors!! It’s your parents and they are here for breakfast. You have strawberry jam, honey, wine, bread and cheese. What is the first thing you open?

Possible Answers

Door – Many angry riddlees are arguing that the door would be the first thing you open because you wouldn’t know it was your parents at the door until you opened the door. While I understand this logic, it’s not correct because the riddle never says that you know your parents are at the door. The riddle explains that your parents are at the door as unexpected guests, but it never actually states that you know this. Plus, the riddle says you wake up, and in order to wake up and walk to the door, most people would need to open his or her eyes at some point.

Mouth - What if you yawn first upon waking and then open your eyes? The only way I think someone would possibly yawn before opening their eyes in this riddle scenario is if the doorbell was one of those soothing types and not the classic ‘ding-dong’ variety that tends to startle most everyone. Or maybe you suck your thumb, and the first thing you would do upon waking is pull your thumb from your mouth.

Fridge – This logic follows that of the door and is defeated by the same logic. It would be very difficult to get to the fridge with your eyes closed. And you would probably step on your cat causing you to open your eyes!

Eyes - This is the most widely accepted answer, and according to Strugnell, the only answer to avoid the humiliation of being a Giraffe on Facebook. If you are asleep as the riddle defines, and the doorbell rings, the first thing you would do is open your eyes upon hearing the doorbell.
Riddle Explanation



In order to solve a riddle, you must be fully in the context of the riddle. Many people are arguing the riddle claims you have woken up, and, therefore, you have already opened your eyes. This is the witty part of the riddle. Upon listening to or reading a riddle, most people will put themselves into the situation in their head and forget details that are hard to visualize. Because it’s hard to visualize being unconscious and asleep at 3am, as the riddle explains, we ignore that part of the riddle and logically go to the next step which is being conscious or awake. Good riddles make us miss the obvious. Adding the extra stuff about breakfast and parents serves to distract you from the waking up portion. If the protagonist of the riddle was changed to “George” instead of “you” and the rest of the riddle was removed, it would be much easier to visualize. It’s 3am, the doorbell rings and George wakes up. What does George open first?
Further explanation

I think what most people are missing is the key word ‘first’ in the original riddle. Karl Zimmerman gave a good alternative riddle to help explain his thought process in the comments below:

It is 3AM. The doorbell rings, you wake up and grab two apples. What is in your hands?

Karl proposes that it depends on if the riddle is asking what is in your hands at 3am or immediately following the story of events in the riddle. In which case, it is impossible to know the correct answer. Is it two apples? Is it nothing because you were sleeping with empty hands? But in the original Great Giraffe Challenge riddle, the final line reads, “What is the first thing you open.” The word first means the very first thing you open in the time frame of the riddle. While the riddle does explain that you wake up during the riddle, it still begins with you asleep because you can’t wake up without first being asleep.

Let’s look at a different way. Pretend the riddle is changed to a list of directions on how to change a tire:

It’s 3am and your back driver-side tire bursts. You get out of your car and open the trunk to get the spare and jack. You raise the car on the jack. You then remove the flat and replace it with the spare. To celebrate, you buy three kinds of soda at the next gas station: Mountain Dew, Coca-Cola, and Sprite. You decide to drink them all in celebration. But before you get a chance, the bumpy road causes all three cans to burst. What bursts first?

Answer: The back driver-side tire.

Do you agree? Is there another answer not listed here?

Penguat Sinyal WiFi

Penguat Sinyal WiFi - Linksys RE1000 Penguat Sinyal WiFi Mudah Digunakan

Linksys RE1000 merupakan perangkat wireless range extender 802.11n 2.4GHz yang berfungsi memperluas jangkauan jaringan wireless. Sementara merk Linksys yang sebelumnya sub-brand dari Cisco, baru-baru ini telah dimiliki oleh Belkin.

RE1000 memiliki desain yang sederhana dengan casing terbuat dari plastik yang kokoh dan memiliki perpaduan warna hitam keabuan. Bentuk yang kokoh snagat dibutuhkan, karena penguna mungkin harus menempatkan perangkat pada tempat yang menonjol dikamar maupun koridor ruangan. Sementara ketiadaan antena dan lampu LED sangat membantu menyatukannya dengan background ruangan.

Perangkat juga dirancang sangat kompak, karena memiliki steker listrik dibagian belakang, shingga tidak ada lagi kabel yang menjulur. Namun Cisco juga menyedakan kabel listrik ekstensi sebagai pengganti steker listrik, bila pengguna ingin menaruhnya dilantai.


Kemudahan dalam menghubungkannya ke jaringan menjadi poin penting dari Linksys RE1000. Bila router yang digunakan memiliki WiFi Protected Setup, hanya perlu menekan tombol WPS pada masing-masing perangkat. Sementara untuk jaringan standar 11n dengan keamanan WPA2, hanya perlu memasang RE1000, memasukkan CD setup ke komputer, kemudian ketik password jaringan yang ada dan seluruh data tersimpan keperangkat secara wireless.



Pengujian extender dilakukan melalui pemasangan berbeda, sehingga bisa diketahui ternyata kegunaannya tergantung pada jenis pemasangan yang dilakukan. Pengujian pertama dilakukan didalam gedung dengan dinding beton dimana sinyal harus menyusuri koridor beton sejauh 5 meter menuju ruangan besar. Sinyal diuji pada tiga lokasi, pertama 7 meter saling berhadapan dengan router, kedua 8 meter dimana sinyal diblokir oleh dinding dan ketiga dengan jarak 10 meter dengan gangguan yang lebih besar.

Hasil tanpa extender, kecepatan data jaringan mencapai 87Mbps (7m), 63Mbps (8m) dan 32Mbps (10m). Ini artinya, bila bergerak hanya 3 meter kebelakang data rate turun hingga 28% dan pada 10m turun hingga 63%. Sementara ketika Linksys RE1000 ditempatkan pada ujung koridor diperoleh data rate 54Mbps (7m), 47Mbps (8m) dan 31Mbps (10m). Terlihat kecepatan data ternyata menurun untuk masing-masing jarak dan ini kemungkinan disebabkan retransmisi yang overhead dan interferensi antara perangkat 2.4GHz dalam jarak dekat.

Pengujian kedua kemudian dilakukan dengan pemasangan berbeda pada rentang yang lebih luas. Pada pemasangan ini ekstender akan difungsikan untuk memperkuat sinyal diantara lantai bangunan.

Sebelum menggunakan RE1000, kecepatan data mencapai 24Mbps di lantai 1, 1Mbps di lantai 2 dan tidak ada sinyal di lantai 3. Kemudian menggunakan RE1000 yang ditempatkan agak jauh dari roter dengan sinyal yang masih dapat dijangkau, hasilnya meningkat menjadi 37Mbps dilantai 1, 11Mbps dilantai 2 dan 1Mbps dilantai 3. Ini menunjukkan pada rentang yang lebih besar RE1000 mampu memperluas jangkauan jaringan secara efektif.

Kesimpulannya, Linksys RE1000 merupakan alat penguat sinyal jaringan wirelss yang mudah digunakan dan sangat bermanfaat dalam memperluas jangkauan jaringan anda. Kekuatan Linksys RE1000 terletak pada kesederhanaan, pemasangan yang mudah, serta mampu menyediakan sinyal koneksi yang solid, karena tidak pernah mengalami penurunan koneksi selama pengujian.
