First off, do not change your SSH port. It won't do a whole lot for you, and it will be more hassle than it works.
I disagree. I changed the SSH port on all our servers. Everyone updated their.ssh/config files and that was the end of the hassle. Bad logins dropped from thousands a day to a handful every few weeks.
Just got back from a quick business trip to Thailand. I brought my many-years-old Nokia phone, a brand-new netbook running Ubuntu, and a USB cable (Bluetooth drains batteries fast).
When I got there I bought a SIM card (DTAC/Happy) for US$1.50 and then paid an additional $4 for 30 hours of online time (could have done one week unlimited 24/7 for $8 but I didn't think I'd use that much).
Stuck in the SIM card, connected the cable, and everything worked straight away. The Ubuntu wireless menu knew the name of the cell company and offered it as option alongside the wifi networks it saw. And that was it. I used it in the airport, on the bus, in taxis, hotels, restaurants, everywhere. Business hotels wanted $10 for one hour's access; I paid less than half that for all I could use in a week.
I used to hunt around for hotels with wifi; I don't think I'll be wasting time on that anymore. Even in expensive countries the mobile access is cheaper, especially when you start including airport wifi charges.
And yet the iPhone is the only one that has actually gotten everyday users to USE their smartphone features to any serious degree. Blackberry users send messages and then cringe about the web browsing. Nokia users (myself included) talk on the phone and then cringe about the web browsing and email. Meanwhile iPhone users are actually doing the things that the other manufacturers have been claiming justified their devices costing 3 times as much as a normal phone.
Interesting! Kinda invalidates a lot of the naysayers. Although they'll probably just say it's Google lying.
Google normally charges $50 per user per year for this service.
If they are giving it away for free, they are getting something that they consider to be worth the same amount.
It could be that they're lying, it could be that they have thought of something that you and I haven't yet, and it could be that the goodwill/marketing angle that you've been pushing is actually worth $1,000,000 per year to them in the case of Yale. Personally, I find that last one very hard to believe. I lean towards "something that you and I haven't yet thought of".
Apple Mail on Macs, Thunderbird on Windows and Linux, and Profimail on phones.
Any one of these runs circles around gmail (or any web mail interface) in terms of productivity when dealing with large amounts of mail. And they all support offline use, which is essential for people who don't spend all day sitting at the same desk.
Though I do use Pine on occasion, mainly when suffering from truly bad connectivity, like Cambodian dialup.
If I send you an email, I might know that my server is pretty secure, but I don't really know how many servers the mail will be routed though, what the security policies might be on those servers, or even whether they might be compromised. And then I don't know whether you're using encryption for SMTP/IMAP on your client end.
You can know quite a bit, if you take the time to look.
You can find out how many servers your outbound mail always goes through by sending a message to yourself at an external email address and looking at the headers.
You can find out whether the recipient organisation handles its own email by looking up the MX records and then checking the IPs for each server to see whose address space they're in.
You can find out whether your correspondent is using SMTPS or STARTTLS, and whether there's an unbroken encrypted chain, by looking at the headers of messages you receive from him or her.
About the only thing you can't always find out on your own is whether he/she is using SSL for IMAP. Though if you're familiar with the institution, you could always ask. Or if it's a large organisation with a public web page for mail configuration details, you could try yourself and see if unencrypted IMAP/POP sessions are entertained, and the same for their webmail. If not, then you can probably rest assured on that score too.
Google does let you look at what they know about you
Have you looked at that? It's clearly not exhaustive. There is tons of data from the correlation of my various Google cookies during general web surfing which isn't listed or even vaguely alluded to. The Dashboard page just lists a bunch of things that were always available by going to the respective Google service sites. It takes a smattering of info from each, and puts them together in one place to assuage the sporadically paranoid.
Email traffic volumes get pretty high. Even if you have local single-instance storage, remote systems aren't smart enough to take advantage of that. For example, an on-campus user sends a 50MB video to a list server at a remote site, rather than sending a link to the video. The remote list server has 30 other subscribers on the same campus. Back comes the same video, in 30 separate emails, through the shared and often already heavily loaded campus Internet trunk(s), to the local email system. Storage jumped from 30Mb in the first user's "sent" store to 1.5GB across multiple inbox stores.
This seems like a specious example; are there any list servers that are configured to allow 50MB attachments?
But more to the point, by moving email off-campus, the university's external link now has to carry what was formerly more contained within the faster local network. This will have some cost, either in paying for increased capacity or in suffering diminished connectivity.
Backups require additional storage, tape or disk. Tape is sluggish, and a full system backup of a large mail server takes a lot of time. Brick level backups are worse. Restoring individuals' accidentally deleted emails is often time consuming, since they seldom can actually tell you the subject line of the message you're trying to restore for them, into their too-full mailbox.
Again, this seems specious. Does Google restore accidentally-deleted emails for users?
Most campus mail systems are commercial applications, such as MS Exchange. They are costly, and the license fees for running them are often more costly and grow faster than your storage. Open source is a great alternative, but some administrations aren't too accepting of anything that they can't buy, for various reasons.
Are there serious universities that run student email on Exchange? I admit I haven't been everywhere, but I've sure never seen that.
Vulnerable to what? The security problems with FTP are (1) passwords are sent in plaintext, and (2) it creates complications for firewalls which may lead to loopholes. Neither of these is a server vulnerability, they are protocol problems.
A prestigious university like Yale can't implement their own webmail/imap system and relies on Google handing all the student data at first place.
Having also attended graduate school there, I was shocked and dismayed by the childish and incompetent atmosphere in Yale's IT services. Prestigious the university may be, but the IT facilities they provide for students are dismal. That Yale ITS are still unable to effectively manage an email system, to the point where it has become easier to cut them out of the loop entirely, comes as no surprise to me. Back in my time, email was accessed via Pine on an overburdened and often-inaccessible Sun machine (minerva.cis.yale.edu anyone?) that was run by some of the most unprofessional people I ever had the displeasure of encountering. Basically, they ran things like they were sysops at some penny-ante BBS.
Compared to my undergraduate experience, at a state school which was (and remains) on the cutting edge of technology, and where the IT infrastructure was effectively and professionally managed, it was a real eye-opener.
Don't they have a CS department? You know most of the UNIX tools which are in use are actually invented/developed by the students studying in that particular university.
You're probably thinking of Berkeley. Yale does have a CS department (not a big one), and there are some smart cookies there, but the smarts seem pretty well contained within the academic sphere.
How much use do you make of folders? That's where most people see problems with Gmail IMAP. Most likely because their data model is really based on tags rather than folders, and the folders you see via IMAP are only a simulation.
When you look deeply enough, all financial indicators are relative. There is no universal archetype of value against which things can be assessed. If everyone else is going down, and you tread water, then by most measures you have grown.
To even have a hope of getting a real sense, you have to take a longer view than just one year, and you have to subtract costs like environmental damage and the accumulation of negative social factors. It takes a long time and a lot of hard work to even approach quantifying this stuff, and a quick glance at one indicator is barely scratching the surface.
I have a lot of faith in India but at the moment the country is not living up to its potential and the government is a big part of the reason why.
Wouldn't the money be taxed when its spent? Doesn't India have some sort of VAT, Sales Tax, etc.?
India has a massive informal economy. It's not like Canada where every business does neat little books and has an electronic cash register that spits out a report for the tax man at the close of business.
I think one of you is talking about client-side Java in web browsers (which is the worst thing in the universe) and one is talking about server-side Java.

That's a very good point. I hadn't thought of it that way before.
I disagree. I changed the SSH port on all our servers. Everyone updated their .ssh/config files and that was the end of the hassle. Bad logins dropped from thousands a day to a handful every few weeks.
That site is really bad at calculating CIDR masks.
Why would someone source-spoof on an SSH attack? It guarantees failure.
Yes, any company would be glad to send you a mailing list of their millions of stockholders.

Or using a structure like maildir in which only new/changed messages need to be backed up.
Have they never heard of incremental backups?

You trust the FDIC and various consumer protection laws with your money.
Gmail users have no such benefactors.

Most freelancers in India are receiving their money as personal payments.
You mean India was seen as a model for how lumbering, stagnant markets could ride through a temporary downturn.
I don't think you understand what "wide-scale economic collapse" means. 2009 wasn't it.
