Are you asking about the best laptop or the best laptop for Linux or what. Seems like any Intel laptop will work with Linux (if wrong state which don't would be useful from someone). Using Ubuntu 14.10 seems fine if you don't like their wanna be for touch screens etc style, Google 'classic menu' and '14 things I did after installing Ubuntu 14 etc.' There is also Linux Mate which you can install over Ubuntu 14.10 for traditional desktop. Also you can install Linux in a Virtual Box Machine if you are running windows something or other. Separate Video card would be nice but not necessary. Linux will recognize your multiple processors in you Multi-Processor CPU unlike Windows which in many cases comes from the store set to default of ONE! <--outrageous.
A friend bought a windows computer and got Windows 7 before that became obsolete and then had to buy new Office because he had WIndows 7 and then a lot of stuff in new Office is slanted to getting you on their cloud service...so Microsoft like Adobe are moving (has moved) to renting the programs instead of actually selling them to you. Indefensible greedy and really good for Linux!
Linux seems not to ever suffer from viruses. And you can crash Linux if you try real hard and it starts up again reliably. Linux is far more reliable than Microsoft and same reliable before Mac went to Intel. Don't know how it is now. But its annoying not to have Flash on Mac Hardware. Or not be able to Play Mac Media on Windows as they come out of the box. Though VLC does largely solve that problem as a replacement for the native media players.
Ubuntu latest with Mint desktop
Free one advantage not held hostage by Microsoft Updates and overpriced Apple hardware
Its unlikely other OS will do anything but try to maintain and grow their monopolies.
In linux there are tones of media, music, and video programs for free and Libre Office is very good. Microsoft office does have RTD and good web to spreadsheet linking but also has errors in a lot of functions they haven't fixed for about 33 years.
Reading and ECG is not as easy as it sounds. Without training no a chance in hell it will mean anything to you unless your flat lining and then you won't be reading anything.
THe only sure fire way to check your heart is to have them pump some fluid in that allows them to see your heart and arteries pumping real time on a screen. A catheter operation in the cath lab. This can be expensive though I have heard there is a good deal in CHicago for a few hundred dollars. The rest, i.e., ECG is not a guarantee of diagnosis, I had several before my infarction as routine check ups and none revealed a 90 percent clogged LAD (Widow maker) and similarly clogged RCA and 50 percent clogged circumflex (which they didn't stent yet because stent cut off line is %70). Perhaps a stress test with the ECG is better. But taking a live camera look is the way to go if you really want to know, you can go in in the morning and be out by the afternoon if all goes well.
The deep insight is nearly dying doesn't necessarily lead to deep insights and perhaps one really has to 'die' and come back to get deep insights and maybe even that doesn't result in deep insights. The other deep insight is, "I didn't die this time and that's ok with me." Deep insight may seem mundane because its just living through proving the obvious things you already knew...might be a third insight. For me dying quickly anesthetized looked a lot better than dying slowly from cancer or in a car crash burning to death or a litany of other possibilities which I assumed was the case before but now I really believe.
I don't display heart attack symptoms well perhaps due to a high tolerance for pain. That said symptoms include some sort of pain, chest (elephant sitting on chest), jaw, in my case a feeling like a baseball pressing into the hollow of my left shoulder. When it started my very first thought was "I am having a heart attack." Which is to say when you have a heart attack its distinct enough from anything else you ever felt on your body you probably recognize it as a heart attack. So don't worry, you will know when you have a heart attack as long as you don't slide into immediate denial. Another sign of a heart attack pain is the pain gets worse and one squirms to try to get away from it (like a leg cramp setting in type squirm)so as it gets worse you will definitely ask to be taken to a hospital unless you are utterly insane. For me it wasn't what I connote as "pain" which has a sense of sharpness to it, it was more like a pressure in an area that was very uncomfortable.
By the way your heart doesn't feel pain itself no nerves for that, which is why there are all these other spots that get reported as uncomfortable or painful because the body "finds someplace else" to express the problem. The other sign is the shortness of breath and gasping...this must be simply because your body is responding to the heart not getting oxygen past the artery blockage (downstream)and is trying to get more oxygen. Note also when you get that second stent they are blocking an artery to insert it so you get a chance to experience the heart attack feeling as per shortness of breath if you missed it the first time.
The main risk after starting to have a heart attack (other than dying)and clearly realizing it, seems to be going into denial and not proceeding immediately to a hospital. That circus lasted almost two hours for me, so by the time the stent cleared the clot I was just on the edge of being on the way out (becoming unconscious). - I even had a smoke in the middle of the two hours before heading to the emergency room!
Next phase was the month to a year as one ponders whether one managed to induce heart failure (enough damage not to pump blood in sufficient quantities) when faced with the tiredness any exertion including rehab seems to induce. The possibility of always being tired IS DEPRESSING. Also there is the "fun" of pains in the area one felt the heart attack pain bringing the question of "am I having another heart attack." And then there are all those stories about how great someone or other felt after having their arteries cleared as if one got a tune up...these stories are B.S. one is looking at about 6 months of not feeling great with any somewhat serious heart attack.
My overwhelming sentiment as the anesthetic set in before they cleared my Widow Maker and inserted a stent was, well, feeling pretty good and the notion there were "worse ways to die," and a certain willingness to go with it if this was it. So I guess I'm not much scared of dying once there.
Mentioning the heart attack is devilish fun in a gathering because most males start to squirm immediately.
There is a disconnect between one feeling fairly back to oneself and other's views of you who has had a heart attack(if they never had one). No one will learn from your example and stop smoking or eating less crap so don't even bother to think so. You'll be lucky if you manage to improve yourself your own bad habits.
After a while one resumes ones devil may care posture towards life with occasional reflective moments on when the
'next one' will be and if there will be a next one(probably).
So as far as great revelations? Not many mostly mundane discoveries. A stent is better than being filleted. Being alive appears better than dead to those of us that are still alive. And next time I feel a heart attack I WILL GET MY ASS TO AN EMERGENCY ROOM ASAP to reduce heart muscle damage that ensues the longer I wait.
