Salient advice about starting a career in tech.
"And if you go in with this mentality, even when startups fail, you succeed. If you put five years into building a company and team, you will end up with a great network of talented and motivated people, lots of first-hand experience, and often some management experience as well.

Why the controversy is still an international issue today — and why Japan and South Korea just struck an historic agreement over it.

I've been spending some time in coffee shops working on my laptop lately. I've learned a couple things of interesting things about commercial captive portals. The Coffeebean shop in Lake Forest uses the Sputnik Hotspot system which blocks Linux user agents from using their service.  It's trivial to prove this by changing my mac address, using my default browser user-agent with Chromium. Attempting to authenticate on the portal will return an error.  Meanwhile my phone and tablet connect without any issue (Apple devices). Changing my user-agent to something like 'Mozilla/5.0 (iPhone...' and suddenly the captive portal will authenticate and I can use the free wifi service.  A small coder/hacker meetup uses the location late at night. They suspected the service simply wasn't available during their meetup schedule until I let them know about the issue.

The other thing I noticed about captive portals was that some of them don't restrict udp traffic over port 53.  This is to allow dns resolution to public resolvers, but it also means I can tunnel VPN traffic without even having to authenticate on the portal.  When I set up a captive portal device from scratch using OpenWrt and CoovaChilli, I made sure to redirect all dns lookups to a local resolver, which always pointed the user to our portal.  It was probably 5 minutes of work.  I'm a little surprised that commercial services don't do this.  But it does make life a little easier for the savvy user who doesn't want their traffic to be sniffed.  The big upside to this is that we can sidestep congestion on the portal network.  Frequently when I visit places on a weekend, the captive portal simply didn't work. It either timed out or returned a some sort of message indicating the captive network was over capacity.  Just like the captive portal that I set up, these services are almost certainly routing all traffic over their own network to do traffic analysis and analytics.  When I tunnel out of port 53, I am bypassing this restriction.  In some cases, I'm even bypassing the traffic redirection and just using the local ISP service, which isn't congested at all!  I can confirm this by running a udp traceroute on port 53.  Anyway, it's nice to be able to get around problems with captive networks.

I've been using +Inbox by Gmail and I like it quite alot.  It still has a couple problems though, mostly missing features that you'd expect from an email client. The worst problem at the moment is that there's no insight into the filtering rules for messages.  You can choose to filter mail from a particular email address to a category, but not all mail from a particular sender should always fall under the same cateogory. One example that just came up is noreply@steampowered.com, which will send promos, updates, and purchases.  Having no visibility into existing rules means I have to trust that Google will always sort my mail appropriately - and I've grown quite accustomed to sorting my mail.

forever looking back
forever tormented
so clever in disguise
and never was she fully realized
take everything you have
take everything you thought you ever knew
and leave it for the goddess figure
true i've been wrong
and i've been taught a lie
and can never go back
to the throes of a normal life
i'm in love with the world
time waits in spirals and in circuits and
we stay in peril and imperfect and
why wait for the silence to be heard when you are
the reason why i'm in love with the world
and when you follow in his shadow
you're devoured by your loss
some pay forever with their winnings
somе stay in debt forever
false i've been true
and it's a lonely line of work that we do
untо thee given nо reply nо affection so
i've been brought up believing a lie
her visiоn clearly burns in my eyes
sun stay surrealist аnd infinitе
give all the true power limitless
now i'm alone with a poison mind
it's enough to know

If I didn't regret getting a Macy's credit card enough already, they made sure I would by requiring FOUR secret questions for possible account recovery. They're really running out of ideas for this stuff. Some genius got paid to come up with, "What is the last name of your childhood doctor?" To which I obviously answered with $n9qXjeBV%z65!Lb.

The guilt trip Apple puts you through for not using iCloud after every ipad update is insane.

A derivative of the Staminus autonuller I created snipes down those rare mega #ddos  attacks so fast that existing connections aren't interrupted. It's the difference between noticing a slight hiccup in your (very latency dependent) game, or potentially having to wait for a reconnection. It completes the denial of service on the targeted IP while basically avoiding any disruption to other customers on the network.
