Comment: This is a terrible idea - here are modifications (Score 1) 597

by dan_in_dublin (#46244811) Attached to: Financing College With a Tax On All Graduates
This is a terrible idea as stated, students need to have some skin in the game - otherwise they'll study pointless subjects such as arts and fail after 1 year

Some modifications

  • students have to pay at least some non-neglible amount of money to prove they're committed to giving their best effort
  • students need to pass a difficult entry exam / other to ensure they're capable of graduating
  • important subjects for economic development are subsidised to extent that makes economic sense (so e.g. if the country needs 5000 engineers a year, then 5000 engineering places are funded).
  • other subjects are subsidised in light of other goals (e.g. 100 funded arts places per year)
  • social funding for disadvantaged students remains a seperate program
  • if a student doesnt make a subsidised place he pays his own way or does somewhere else with his life
  • money to pay for above comes from grad tax, general tax, it's all good

This is stupid, there's no benefit to using https on many sites. We can understand a security need by thinking about confidentiality, integrity, and availability. If I connect with https to a site which doesnt have my personal data (e.g. news sites) there is no benefit to confidentiality - the site is availabile to anyone, the info isnt confidential to me. Integrity - without 2 way authentication (which https typically doesnt do) there is only a marginal increase in difficult to compromise the integrity of a http request or response. Why would anyone do that with something like news though. Availability https doesnt change anything, probably makes it worse as the site has to negotiate TLS sessions Accessing sites with personal data, banks, email, faceboook - https is essential. Accessing sites without personal info, such as news, https accomplishes strictly nothing, it's is a waste of cpu cycles and the energy that powers them

even if the message is sent encrypted thus preventing attacks from the network under govt coercion.. which would be a step forward, does android let you do this ? technically it wouldnt be hard but is there a way to say to android that this type of sms should be opened with this application ?

however, security wise - the keys to decode the message and the messages are on the device. so when the app does to delete the message does it really delete ? probably not, the underlying os may well leave the message and just delete the filesystem reference. similarly for the keys. so if the device is confiscated, there's a good chance all the encrpyted messages can be recovered. also if the nsa dont run the app after confiscating the device then the app wont be able to delete its data store

with respect to the sender specifying how long the message can remain without being deleted. this depends on the receiving app honouring the 'delete after n days' part of the message. if the receiver installs a clone silent sms program which doesnt honour such requests they'll never get deleted. so the security offered to a sender is assured by the difficulty of creating a clone app. this difficulty depends on the effort silent message makes, if they dont explicitly engineer for that kind of security it will be trivial, if they do explictly engineer for that then it'll be medium difficulty. more than this cant be achieved with this architecture

another factor is that all of the millions of cars are each emitting pollution from thier exhaust pipes, each need to have catalytic converters and other anti-pollution technology In electric cars, the pollution is centered at the power plant, meaning only one instance of anti-pollution technology is needed for all the cars charged by that powerplant. This results in cheaper and cleaner vehicles. In addition, the power cells of the cars are recylable at the end of their life

guns dont kill pepole is nonsense and anyone who believes it is a victim of gun lobby PR. snappy one liners may be easy to remember but that doesnt mean they correspond with reality it's obvious that killing from a save distance by pulling a trigger is different than swinging a blunt instrument at close range where the first blow may miss, the victim has a chance to defend themselves or bystanders can intervene Put apart from the obvious flaws; if it were true then every country would have more or less the same homicide rate but the means of murder would be different. The homicide rate in the us is 2011 was 4.8 per 100,000. In Ireland 1.3 per 100,000. Note that in Ireland there is not an additional 3.5 homicides by blunt instrument because people cant get guns.

sure, what's more likely
  1. 1. lawyers spontaneously take an interest in health implications of plastic bag recycling, especially for implausible scenarios such as someone coughing into a plastic bag before using that bag for food packaging
  2. 2. vested interest attempts to establish a narrative on plastic bag recycling to influence public opinion against a sound environmental measure, perhaps in view of the result that plastic bag consumption drops by 99% in places which introduce incentivies for plastic bag recycling

isnt this story where there was a sick girl, sharing a hotel room with lots of other people, the girl used a reusable plastic bag from a store as a bin liner in the bathroom and after a number of her room mates fell ill they found some germs on the plastic bag bin liner it's nonsense to suggest either - the bag is a more likely reason the illness spread than any other reason that comes with sharing a hotel room - that bags in general spread illness - that the exact same thing cant happen if we dont re-use plastic bags (I was using store plastic bags as bin liners long before there was a push to re-use plastic bags) this is simple that a person with a contagious illness spread it to people in her proximity, and some manufacturer of plastic bags has jumped on that to create a story against recycling plastic bags. clearer the manufacturer has a vested interest in plastic bags not being reused, shame on the 'researchers' who lent their name to this

if the attacker has sufficient access to the host to study the vm's execution profile then i suspect the attacker can do a lot more than capture that key.. in the uses I would expect people to care about, web services running on a vm on the net, this implies that the attacker already has ssh access to the host machine. so an assumption of this vulnerability is that the host system is completely compromised. in such a case the attacker will have other options to get that key. as a side note, i dont know if it would be a good thing to fix this problem, you pay for perf for web servers so disguising the computation to mitigate such an attack would cost way more than it would achieve

dont photons have an energy that is inversely proportional to the wavelength (shorter wavelenths = photons at higher energy).. i'm no particle physicist but something emitted the photon which is the particle by which the xrays and all em propagate.. then photons get released when electrons drop to lower energy levels in their atomic orbits.. so as the matter of the cloud compresesd in the effect of the black hole's gravitational pull, the temperature of the matter incresaes, the energy of the electrons increases correspondingly, the electroncs go to higher orbits around the atom and they drop back to lower orbits by releasing photons. so maybe they can measure the temperature of the atom at the point where the electron was released by looking at the wavelength / other properties of the photon ? wasnt the temperature of the big bang measured via the universal background radiation which is the photons released by the matter in the universe about 300,000 years after the big bang (the point at which temperatures had cooled sufficiently for electrons to get into stable orbits around atoms ?

The irish science minister demonstrates his scientific acumen by endorsing an author whose website [http://www.theoriginofspeciousnonsense.com/index-2.html] and book propose arguments such as
"Our Milky Way/Universe is so mathematically precise and orderly that we can predict an eclipse of the moon 176 years in advance to the 16th of July 2186, that's 176 years in advance of today to the very second.. CHANCE? — NO."
"It is sacrificing reason on the alter of treason to accept that the greatest construction of all time.. a human being with a brain is the result of chance, randomness and destructive mutations. It is the irrational three legged chair of hopeless speculation that bears no resemblance whatsoever to reality and observable functioning perfect order."
