Comment the A in ADSL (Score 1) 107

After a two weeks of trying to get comcast to fix my lack of connection I switched to DSL. I'm getting the advertised DSL speeds. What I'm wondering is why the hell is the upload speed of ADSL pegged at such a crappy ratio to the download speed. Cable has about a 2:1 ratio but ADSL is about 30:1. My upload speed is 0.8Mbs on a 20Mbs download line. Why? what's the physical limit on DSL that cable doesn't have on the asymmetric division? It used to be that this wasn't a big deal since relatively few people upload much. But these days uploading for common people is ubiquitous: your phone by default wants to push every photo to the cloud, your backups go to the cloud, and it's not uncommon to want to e-mail a 20Mb word document. So upload speed has become an issue.

It becomes a major issue when a long duration upload (say a backup) chokes off even the modest handshaking upload that other download streams require and your Amazon prime fire TV stops working smoothly.

Are the DSL companies doomed by physics or their market price point if they can't increase this without raising prices dramatically? Why would this be costly? I'd gladly trade a megabit of download for another megabit of upload.

Comcast seems to have incentivized its india based outsourced customer service to optimally work against comcasts own interests. namely they first employ an incompetent first-line who cannot reason logically what the problem is and make you follow the script even after five previous calls (which apparently are not incentivized to make notes). thus they make their money from answering calls and getting you to just give up. then the next technique is to flat out lie("we will have technical call you in 30 minutes sir, this I promise to you. Now being such a good customer I have an upgrade deal to offer you"_) and finally even in the middle of the nightmare non-performing service they take the time to offer you additional costly upgrades. This only makes sense if you consider what the service center makes its profit on as opposed to comcast (retaining customers).

The DSL company also seems confused at well but at least they make as many errors in my favor as they do against it that it can't be a deliberate strategy.

When I was at school (tr:US high school) we had a 2 litre coke bottle three quarters full of the stuff. Just sitting there in our study room...

We had bought the iodine at one chemists shop, then gone to another to get the ammonia (buying both in the same shop seemed like a bad idea to us) and then made it by the litre. I dread to think what it would have done if it had dried out.

Comment backdoor versus sidedoor. (Score 2) 102

Discussing this as a "backdoor" conflates this with the usual hidden backdoor which is a bad thing. Putting in a backdoor that is freely accessible and leaves no trace of its accession is ill advised. But I fail to see why there are no technological means to secure keys for multiple parties. you can even have crypto so multiple parties must agree so for example like my safe deposit box the bank and I both have to agree that I am me.

Now that's a different question of whether
1) I might encrypt the data on my own or use a thrird party client that uses googles services but keeps things encrypted in passage. That defeats the abililty to side door googles encryption.

2) I might off shore my data to someplace outside such laws (do I trust them is another matter).

3) the dent this might cause in googles popularity outside the US--I actually doubt this since de facto it has been the case in the past that the NSA had free range of google and no one cared deeply. But Will china also demand that google also let it have side door access as a condition of doing bussiness there? Still while a mess it's not technologically difficult.

4) an even stickier issue might be who all has to agree to unlock the data. Google+NSA. Google+China. those are doable. but Google+NSA+China is a problem. China might not want the NSA peeking at chinese national accounts without it's permission. Nor perhaps North Korean or any number of disputed places the NSA is interested in.

So there's a political mess here and some ways consumers can defeat it, but I fail to see why someone like Bruce Schneir would say there's no technical means to do this at the level of google or apple or major sites when there plainly is.

I suspect processed foods are not harmful. A raw food diet is a lot likely to be less optimal (basically, cooking - which is processing food - is what made us human: processing our food allowed us to break it down a bit meaning a simpler, more efficient digestive process, allowing us to have larger brains).

If you cook from fresh ingredients, guess what you're still eating processed food. Just because the food processing happened in your home, doesn't mean it's not processed food. It doesn't matter where the processing occurred - in your home, in a factory, or wherever, so long as the food doesn't contain excessive quantities of crap. I think the real answer is avoid crap foods. Foods with large quantities of refined sugar for example. I think the main things of home cooking (processed foods processed in your home) is that you know what went into the process so it's easier to avoid the crap simply by not adding it to the recipe.

I'm 43 and people who meet me think I'm in my 20s (well, apart from the receeding hairline but I've had that since a teenager). I drink, I eat processed foods all the time, I have plenty of milk, not too much sugar, and love gluten. I exercise a bit (mostly ride my bike). I drink tea (hot with milk, no sugar) by the gallon. I eat ice cream and chocolate probably too much. I'm 5'11" and weigh 152lbs.

Unless you've got a specific condition which gluten aggravates (celiacs etc.), gluten free diets are a fad diet that just take some of the joy out of food. It's no more healthier than a tasty gluten laden diet.

I'm in a similar situation and it will surprise he hell out of you how little design choices or sudden small changes just wreck a senior persons ability to use a device. When Google moved the reply compose window from new page to an inline division at the bottom of the page seniors I know were unable to adjust. What seems to be lost is the cognitive clue of the new page load or Pop up window that one is changing context. The subtle sliding open of a new field at the end if the message window that you may need to scroll to proved almost unlearnable. Sure it's better Ajax than a new page load but it's not good for intuition. Things that are modal rather than expose on mouse over are much better for arthritic or less attentive mouse users. Likewise all those genie effects and skeimorphic interfaces and 3d pulsating buttons apple seems to be running away from are exactly the clues seniors need.

When it comes to physical appliances having rotary switches that change menus but have no absolute rotation position are death to people with macular degeneration or arthritis. The worst are the dials on washing machines which free rotate when pulled out loosing the correlation of clock positional orientation and function. You can't buy a washer with just one big red button that says just wish my fucking clothes instead you have to finely rotate a knob past the permeate press setting to the normal settings beginning of cycle. But don't go too far or you miss the wash portion and just skip to the spin cycle. Behold needs this control? Why does apple or dishwasher makers think it's a good idea to make all buttons the same size shape and in one row? These thing just don't work for partly sighted or people with atheist is or motor impairments. Stroke victims can just give up. Making buttons different and putting some space between them would help

The floating ad bars at the bottom of slash dot for mobile users are impossible for non nimble fingers to dismiss , they are deliberately misleading appearing to be controls, and make the real buttons on the page unreachable.
