Flying with Head Cold or Sinus Problem

During the recent holidays, I unfortunately caught a head cold during my vacation trip and had to fly several legs with sinus congestion.

It is strongly recommended not to fly as a required crew member or passenger with a head cold, ear infection or sinus problem by medical and aviation experts.

Upon takeoff and especially landing, you cannot equalize pressure between the airplane cabin and the passages inside your ears and sinuses.

As a result, the following injuries can occur:

  • pain, sometimes excruciating
  • ruptured eardrums and middle ear problems
  • damage to sinuses.

The best advice is to either cancel the trip, or take surface transport like a train or boat if possible.

If you’re really stuck flying, here’s some further advice that can help if you’re a passenger:

  • short flights under 2 hours can cause less problems, as they typically stay under 25,000′
  • You will need a nasal decongestion drug to open your sinuses and ear passages. See an ENT doctor before flying if possible.
  • in the USA, take a Benadryl (pseudoephrine) capsule 5 minutes before takeoff and landing (if you have normal blood pressure)
  • in some Asian countries, Tremenza (pseudoephrine with triprolidine) tablets are available, but they take longer to become effective than capsules (if you have normal blood pressure)
  • Drizine (oxymetazoline hydrochloride) by Schering-Plough is a nasal spray that can also be used.
  • carry or request a bottle of water and drink it on takeoff and landing. You will be swallowing more than usual to equalize pressure, which you won’t be able to continue with a dry throat.
  • if you’re experiencing pain, especially on a USA airline, notify a flight attendant so that they understand it’s a minor medical issue and not a security problem.

Note that pseudoephrine is a controlled substance in the USA and other countries, so if you have a prescription, carry it with you when going through Customs, or discard the drug in a place safe from children.

I used the above techniques to fly 6 legs as a passenger with minimal discomfort, but I’d imagine luck was also on my side this time.

If you have chronic sinus problems when flying, then see an ENT doctor and request an endoscopic examination to look for blockages from polyps, infection or waxy buildups.

Happy New Year 2012 from Bali with Angry Birds and Beer

Happy New Year 2012 from Bali, with Angry Birds and beer! :)

Traditionally, New Year’s in Bali is celebrated with a fireworks display near Kuta Beach. And lots of beer.

Bintang Beer comes in 2 bottle sizes, the 330 mL “Pint” shown above, and the 620 mL “Bremer” typically carried in each hand by Australian tourists – “Just in case, mate.” The brewer is advised by Heineken.

Bintang means “star” in Bahasa Indonesia.

Angry Birds is a cultural phenomenon in Southeast Asia, with t-shirts, backpacks and plush toys featured at many stores.

Barnes & Noble Nook Color 7″ Tablet BNRV200 Review

Nook ColorI bought a refurbished Barnes & Noble Nook Color 7″ (developer nickname “encore”) tablet on sale for $119 (originally retailed at $249, now $199.)

The unit that arrived was a model BNRV200 with Software version 1.2.0 installed.

In short, the Nook Color is a remarkably capable and polished 7″ tablet.

I use tablets mainly for final software testing of websites, and it will be handy to have a 7″ Android for that.

The Nook team at B&N should all get a bonus for their great work and attention to detail.

Getting Started

After recharging the battery and agreeing to a 100 page Terms and Conditions form (!), you must register online via WiFi with a free B&N account to “activate” it. (No credit card is required until you want to buy a book or app. No PC is needed.)

Hardware

  • 7″ “VividView” glossy color display is 16 million colors, 1024×600 and bright. Great screen.
  • built-in speaker is adequate for home use, but not loud enough if there’s ambient noise, so you will need earphones for use in public
  • has microSD slot that supports up to 32 GB storage
  • has custom miniUSB port (2-level contacts) and custom cable needed for charging from wall at 1.9 amps. (Will only charge slowly when connected to a PC. My MacBook Pro sometimes displays a warning dialog that says there’s overcurrent and disables that USB port.)
  • RAM is 512 MB, and the 8 GB total internal flash memory is partitioned into 2 GB system, 5 GB content and 1 GB sideloading (end-user)
  • WiFi b/g/n works with any access point that you can login to, plus B&N access points that provide free extra services like book previewing. Some forum posts report that older access points may not be compatible.)
  • TI OMAP 3621 CPU is a single-core ARM Cortex 800 MHz
  • long battery life using internal Li-ion Polymer battery (over 8 hours)
  • solid-feeling, but kind of heavy at 15.1 oz.
  • useful corner cutout in case for locking to a desk or anchoring a strap on the unit.

Software

  • Android-based (originally Android 2.1, but has been updated) with customized UI
  • complete all-around eReader and Internet-capable tablet.
  • some games are included, including chess, sudoku and crossword puzzles, along with Pandora music and email apps. (Angry Birds is a $2.99 downloadable purchase.) Notably missing are free solitaire and minesweeper games, and there’s no free calculator app.
  • the included software is fine. If B&N drops support in the future, there is third-party Android software for this device.
  • file formats supported for reading include: ePub, BBeB, PDF, XLS, DOC, PPT, PPS, TXT, DOCM, XLSM, PPTM, PPSX, PPSM, DOCX, XLSX, PPTX, JPG, GIF, PNG, BMP, MP3, AAC, MP4. Quickoffice® Pro app can be used to edit many Microsoft formats.
  • free in-store WiFi access, free 1-hour eReading per day, free use of Angry Birds Golden Eagle feature to clear a level.

Usage Notes

  • it’s a good idea to examine the settings page and customize them. I disabled location reporting and forms memory.
  • international users (billing address outside the USA) can’t use the store.
  • there’s a bug in Software Version 1.4.1 when entering your credit card information: the form subtracts 1 from your month, so choose the next higher month, or your card will be declined with a “processing error” dialog
  • battery life can be extended by setting WiFi to “Off” (airplane mode) when using it as an eReader, or putting it into sleep mode.
  • the power button is multifunction: 2 seconds is on or sleep, 5 seconds is power off, 20 seconds is software reset.
  • I use a netbook case to store it. The least expensive official accessories are the Aalto Cover ($14.95) and the Silicone Frame ($19.95)
  • Software version 1.4.1 does not have third-party support at this time.

B&N “Guru” Notes

I talked to a store employee and he had this advice:

  • the straps they sell are “for decorative purposes only”, so don’t rely on them to be strong enough for carrying your Nook Color
  • if you don’t want to use your existing credit cards for purchases from the app store, you can buy a prepaid VISA or MasterCard debit card and use that alone, or in combination with a gift card. I checked on prepaid cards at Safeway and found that there are steep fees and require your name, address and SSN to purchase. Some credit cards also allow a temporary number to be generated, sometimes known by the brand names SafeShop or NetSafe. Due to a forms bug, you need to increase the month by one.

Nook Color Tablet (BNTV250) – Next Generation

Similar screen as older Nook Color, but double the RAM (1 GB) and flash (16 GB), and still only 1 GB partition for end-users. Dual core 1 Ghz CPU. Netflix app and better video capability. 50% more battery life. Third-party software support unknown due to lockdown, prolly requested by Netflix’s content providers.
