Sunday clip: Linux Sets You Free

Bài hát vui nhộn được sáng tác và thể hiện bởi Scott Dastrup.

The day the routers die

Bài hát khá thú vị của Gary Fieldman, nói về kết cục của IPv4 và sự cần thiết của IPv6.

Lyrics:

a long long time ago
i can still remember
when my laptop could connect elsewhere

and i tell you all there was a day
the network card i threw away
had a purpose - and it worked for you and me…

but 18 years completely wasted
with each address we’ve aggregated
the tables overflowing
the traffic just stopped flowing…

and now we’re bearing all the scars
and all my traceroutes showing stars…
the packets would travel faster in cars…
the day… the routers died…

Chorus (ALL!!!!!)

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s’pose we’d better give it a try
I suppose we’d better give it a try

now did you write an RFC
that dictated how we all should be
did we listen like we should that day

now you back at RIPE fifty-four
where we heard the same things months before
and the people knew they’d have to change their ways…

and we - knew that all the ISPs
could be - future proof for centuries

but that was then not now
spent too much time playing WoW

ooh there was time we sat on IRC
making jokes on how this day would be
now there’s no more use for TCP
the day the routers died…

Chorus (chime in now)

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s’pose we’d better give it a try
I suppose we’d better give it a try

I remember those old days I mourn
sitting in my room, downloading porn
yeah that’s how it used to be…

when the packets flowed from A to B
via routers that could talk IP
There was data… that could be exchanged between you and me…

oh but - I could see you all ignore
the fact - we’d fill up IPv4

but we all lost the nerve
and we got what we deserved!

and while… we threw our network kit away
and wished we’d heard the things they say
put all our lives in disarray

the day… the routers died…

Chorus (those silent will be shot)

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s’pose we’d better give it a try
I suppose we’d better give it a try

saw a man with whom I used to peer
asked him to rescue my career
he just sighed and turned away…

I went down to the net cafe
that I used to visit everyday
but the man there said I might as well just leave…

and now we’ve all lost our purpose..
my cisco shares completely worthless…

no future meetings for me
at the Hotel Krasnapolsky

and the men that make us push and push
like Geoff Huston and Randy Bush
should’ve listened to what they told us…
The day… the routers… died

Chorus (time to lose your voice)

bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I spose we’d better give it a try
I suppose we’d better give it a try

Every OS suck

Bài hát cũng có thể xem là một biên niên sử máy tính và hệ điều hành từ những năm 1970 đến nay. Tác giả của bài hát này là nhóm Three Dead Trolls in a Baggie.

Chúc các bạn cuối tuần vui vẻ ^^.

The lyric:

You see, I come from a time in the nineteen-hundred-and-seventies when
computers were used for two things - to either go to the moon, or play
Pong… nothing in between. Y’see, you didn’t need a fancy operating
system to play Pong, and the men who went to the moon — God Bless ‘em —
did it with no mouse, and a plain text-only black-and-white screen,
and 32 kilobytes of RAM.

But then ’round ’bout the late 70’s, home computers started to do a
little more than play Pong… very little more. Like computers started
to play non-Pong-like games, and balance checkbooks, and why… you
could play Zaxxon on your Apple II, or… write a book! All with a
computer that had 32 kilobytes of RAM! It was good enough to go to
the moon, it was good enough for you.

It was a golden time. A time before Windows, a time before mouses, a
time before the internet and bloatware, and a time…
before every OS sucked.

*sigh*

[singing]

Well, way back in the olden times,
my computer worked for me.
I’d laugh and play, all night and day,
on Zork I, II and III.

The Amiga, VIC-20 and the Sinclair II,
The TRS 80 and the Apple II,
they did what they were supposed to do,
wasn’t much… but it was enough.

But then Xerox made a prototype,
Steve Jobs came on the scene,
read “Of Mice and Menus,” Windows, Icons
a trash, and a bitmap screen.

Well Stevie said to Xerox,
“Boys, turn your heads and cough.”
And when no-one was looking,
he ripped their interfaces off.

Stole every feature that he had seen,
put it in a cute box with a tiny little screen,
Mac OS 1 ran that machine,
only cost five thousand bucks.

But it was slow, it was buggy,
so they wrote it again,
And now they’re up to OS 10,
they’ll charge you for the Beta, then charge you again,
but the Mac OS still sucks.

Every OS wastes your time,
from the desktop to the lap,
Everything since Apple Dos,
Just a bunch of crap.

From Microsoft, to Macintosh,
to Lin– line– lin– lie… nux,
Every computer crashes,
’cause every OS sucks.

Well then Microsoft jumped in the game,
copied Apple’s interface, with an OS named,
“Windows 3.1″ - it was twice as lame,
but the stock price rose and rose.

Then Windows 95, then 98,
man solitaire never ran so great,
and every single version came out late,
but I guess that’s the way it goes.

But that bloatware’ll crash and delete your work,
NT, ME, man, none of ‘em work.
Bill Gates may be richer than Captain Kirk,
but the Windows OS blows!
And sucks!
At the same time!

I’d trade it in, yeah right… for what?
It’s top of the line from the Compuhut.
The fridge, stove and toaster, never crash on me,
I should be able to get online, without a PHD.

My phone doesn’t take a week to boot it,
my TV doesn’t crash when I mute it,
I miss ASCII text, and my floppy drive,
I wish VIC-20 was still alive…

But it ain’t the hardware, man.

It’s just that every OS sucks… and blows.

Now there’s lih-nux or lie-nux,
I don’t know how you say it,
or how you install it, or use it, or play it,
or where you download it, or what programs run,
but lih-nux, or lie-nux, don’t look like much fun.

However you say it, it’s getting great press,
though how it survives is anyone’s guess,
If you ask me, it’s a great big mess,
for elitist, nerdy shmucks.

“It’s free!” they say, if you can get it to run,
the Geeks say, “Hey, that’s half the fun!”
Yeah, but I got a girlfriend, and things to get done,
the Linux OS SUCKS.
(I’m sorry to say it, but it does.)

Every OS wastes your time,
from the desktop to the lap,
Everything since the abacus,
Just a bunch of crap.

From Microsoft, to Macintosh,
to lin– line– lin– lie… nux.
Every computer crashes,
’cause every OS sucks.

Every computer crashes… ’cause every OS sucks!

Alice and Bob

Alice và Bob là hai nhân vật thường xuyên xuất hiện trong các bài giảng và các vấn đề về mã hóa và bảo mật. Việc sử dụng hai cái tên này bắt nguồn từ việc các vấn đề mã hóa thường phải đề cập đến "A muốn gửi một thông điệp cho B". Ngoài Alice và Bob, còn có một số nhân vật khác như:

- Eve: người nghe trộm thông tin, được biết như là kẻ tấn công với hình thức passive.

- Mallory: không như Eve, Mallory là kẻ tấn công hiểm độc. Mallory luôn muốn sửa đổi thông tin, thay thế bằng tin khác hoặc nhân bản các tin lên,...

- Trend: may mắn cho Alice và Bob, họ luôn có sự giúp đỡ của Trend, bên thứ ba, người cung cấp các giao thức an toàn để truyền tin.

Bài hát sau do MC Plus+ (*) sáng tác. Bài hát nói về mối quan hệ của Alice, Bob, Trend, Eve và Mallory, cùng với các vấn đề liên quan đến an toàn mạng như các thuật toán mã hóa, ưu nhược điểm của chúng.

[*] MC Plus+ tên thật là Armand Navabi, đang nghiên cứu về khoa học máy tính tại đại học Purdue.

Lyric:

Alice is sending her message to Bob
Protecting that transmission is Crypto’s job
Without the help of our good friend Trent,
It’s hard to get that secret message sent
Work tries to deposit the check of your salary
But with no crypto, it’ll be changed by Mallory
You think no one will see what it is, you believe?
But you should never forget, there’s always an Eve…

[Chorus]
‘Cause I’m encrypting s**t like every single day
Sending data across the network in a safe way
Protecting messages to make my pay
If you hack me, you’re guilty under DMCA

DES is wrong if you listen to NIST
Double DES ain’t no better man, that got dissed
Twofish for AES, that was Schneier’s wish
Like a shot from the key, Rijndael made the swish
But Blowfish is still the fastest in the land
And Bruce used his fame to make a few grand
Use ECB, and I’ll crack your ciphertext
Try CFB mode to keep everyone perplexed

[Chorus]
‘Cause I’m encrypting s**t like every single day
Sending data across the network in a safe way
Protecting messages to make my pay
If you hack me, you’re guilty under DMCA

Random numbers ain’t easy to produce…
Do it wrong, and your key I’ll deduce
RSA, only public cipher in the game
Creating it helped give Rivest his fame
If we could factor large composites in poly time,
We’d have enough money to not have to rhyme
Digesting messages with a hashing function
Using SHA1 or else it won’t cause disfunction

[Chorus]
‘Cause I’m encrypting s**t like every single day
Sending data across the network in a safe way
Protecting messages to make my pay
If you hack me, you’re guilty under DMCA

Password confirmed. Stand by…
