HP-16C

The newest addition to the computing family here at the studio is a museum-quality specimen of the Hewlett Packard 16C Computer Scientist acquired through eBay.














Take a look at this great article titled "Long Live the HP-16C" by Valentin Albillo here.
Love this device! Of course, the HP Museum site has useful information about this and many other HP calculators. If seeking the missing manual, there is a scanned version here.

Also, Cameron Paine has a faithful simulation running on the Windows OS here. (Select the menu item View...Classic for the nostalgic visual replica.) Another version for the browser is meh.

Update 20150227:
One Voyager was not enough! We added a near-flawless HP-11C.

Clash of Clans Strategy Guide


Below are tips for Clash of Clans, serving as guidance from level 4 onward. First, focus on upgrading resource acquisition and storage. Note that upgrading the gold mine requires elixir while upgrading the elixir collector requires gold. Be aware that operations are halted during upgrade of the mine and collector, thus sometimes it is necessary to simply wait for resources to build up before proceeding.

After upgrading the Town Hall beyond the first level, build additional mines/collectors so only one is down during upgrade. Remove obstacles to find gems. Be careful with some of the interface elements as it is easy to accidentally spend hard-earned gems. Save every gem to eventually afford a third builder hut for 500 gems.

The first 19 levels is mostly about building a solid home-base with good resource collectors, seeking opponents with weak defenses, and collecting trophies. Difficulty might be found in the single-player "Fool's Gold" and "Immovable Object" challenges...these levels require some ingenuity or additional research at the laboratory.

Build a strong defense by creating a double-wall around cannons, archer towers, and resource storage. Mines can benefit from defense protection when placed just outside the wall within range of defense units. Check that opponents cannot deploy forces within the wall...when moving an object, watch for the highlighted areas on the ground to be certain there are no holes. Lay traps and bombs on the interior and reinforce the inner wall around the secure area. (see diagram above) The interior can serve for resource storage or for housing the town hall and eventually additional defenses like the wizard tower.

When attacking an opponent, if there are undefended buildings in the corner areas, deploy a troop to each building at the start of the battle rather than waiting for the collective to spend valuable time running to every corner near the end.

The gem box yields 25 gems and recurs every 8 days (on average).

Edgeworld Strategy Guide

Strategic tips:
1) When attacking a player who is online, do not end the attack prematurely; keep the clock running for the full 5 minutes. This can help frustrate the opponent.
2) When using a 15 minute XP boost, attack Factions (PvE) about half the current level. When the experience bar reaches maximum, end the battle and re-attack. This can help accelerate level gains to a rate of about 100 levels in one 15 minute boost.
3) When given the opportunity to spend a Cerulean core, choose offensive structure upgrades such as warp gates, tech lab, fleet academy, generals quarters, etc.
4) Be cautious with Battle Cruisers on higher level bases. They can get wiped out easily.
5) Always keep queues full: buildings upgrading and troops training.

Star Wars: Tiny Death Star Strategy Guide

Inheriting its game mechanics from Tiny Tower, sales can be maximized in the same way within a Tiny Death Star: After building 20 or so levels, focus on re-stocking only 3-coin inventory. See the prior article for a bit more on this. Work toward evicting any Bitizen not in their dream job. On each apartment floor, try to keep one slot open for a new move-in. (Evict any new tenant if no dream-job is available.) Save Imperial Bux to upgrade the elevator.

Formulas for Squircles

The Desmos online graphing calculator is useful for visualizing mathematical equations such as the squircle.

The formula for the red circular arc is for comparison. The blue line is the squircle and the orange and green lines are higher order shapes. Odd values produce tangents. Closer inspection of the higher order shapes reveals a gap above of the x-axis. Why is this?
















Additionally, the calculator supports sliding variables so the numbers 2,4,6,8 above can be replaced by the variable "a" in a single equation and assigned a stepping value of 2. (Also try 0.2)

Pocket Trains Strategy Guide

Below are some tips for Pocket Trains (iOS version 1.0.6), serving as guidance from level 4 through level 20 with expansion to the North American continent. An enjoyable and engaging interactive experience with some geography lessons for good measure.

Getting started:
Aim to build and operate five railroads between 11 cities in Europe. This is sufficient to fund the start up phase.

The Jobs button leads to a list of available cargo to haul, grouped by city, mixed with items parked in the yard. Upgrade the station to increase the yard size. Each prospective shipment has a coin-number assignment (1 through 4) to indicate relative value of the job. Maximize profit by prioritizing selections in the following order: bux, crates, event cargo, 4-coin, yard cars. Choose 3-coin and 2-coin only if the higher priority shipments are not available. This strategy might involve hauling a few pieces in the opposite direction temporarily. Choose to haul as many cars as possible. Don't bother with 1-coin offers unless there's no better option and it is delivered at the next destination - storing single coin cars clutters valuable yard space.

Let's take a closer look...

Galaxy Empire

We reviewed this free on-line strategy game last year. Since then, we've developed eight planets, acquired five moons, gained over 27 million points, and ranked in the top 70 players on one of the many game servers. With this experience, we've compiled a few tips and tricks learned along the way:

1) As new planets are developed, don't bother with solar plants...they are a waste of space on the planet. Fusion plants are much more efficient. If a little extra power is required, put up some solar satellites. Here's an example: if Energy Tech is researched to level 15, the output from a level 16 Fusion plant is 8889 energy. The solar plant on the other hand requires level 28 to generate 8075 energy - not quite as much, yet it uses up valuable planetary space that can be put to better use by increasing mines to higher levels.

2) After making careful observations of all metrics across planets, research, production, construction, ship efficiency, battle reports, etc., we could find no benefits to improving Plasma Technology beyond level 10, other than gaining double score points for spending resources on research. We asked Support about the specific effect when upgrading Plasma Tech beyond level 10. Here is their response:
The plasma tech can be used in the construction of the new fleet, the tech has powerful combatting force. Every upgrading the tech can let you to construct the higher one or the stronger weapon or fleet. if you did have the relative tech, you can not have other fleets or weapon.
Huh? We were hoping for a comprehensible response such as, "there is a 1% gain in metal mining production", or "there is no specific gain beyond level 9", or "good idea - look for an improvement in the next version".

3) Each scan using the EU-X radar array costs 50K in gas. Be sure to have a reserve available on the moon.

4) Try specializing some planets. By sacrificing a few levels in the other mines on a planet, a higher gain can be had in another. For example, a level 39 metal mine with Lv7 four-star metal galactonite equipped on the planet produces 770K/h. That's over 18M per day...not bad!

5) Researching Hyperspace Tech reduces fuel requirements for fleet transit. As a result, there is a corresponding increase in the amount of cargo that can be loaded. It doesn't change the cargo capacity of the ships, but be aware that the fuel used for flying is also loaded into the cargo bay, therefore reducing fuel requirements increases space for transport.

6) To identify where improvements can be made, create a one page spreadsheet to tally building levels and production numbers across planets. For example, to optimize for Destroyer production, aim toward the ratio 48:40:12 - that is 48% of total production should be metal, 40% crystal, and 12% gas. Our next goal is to determine the optimal configuration of mines for a given planet size with respect to Destroyer production. Stay tuned.

7) On the defensive side, every 16 ion cannons is equal to one large shield dome. It takes 2.5 plasma cannons to take out a dreadnought and 3.5 to eliminate a destroyer. Build accordingly.

8) Expenditures of gas to move ships around does not contribute toward score.

Root Beer Research

Barq's root beer tastes better the colder it gets. Near freezing, it becomes more syrupy and fizzy...refreshing on a warm day, especially after some heavy-duty yard work. Looking at the ingredients however, it is sad to see HFCS (high-fructose corn syrup) and sodium benzoate. Time for a change. Further investigation online revealed a store appropriately named "The Root Beer Store". They carry over 100 brands of root beer, and although prices are a tad steep, we are seeking these four brands of root beer: Bulldog, Virgil's, Sprecher, and Capone. (...almost sounds like a law firm!) These selections are based on favorable reviews found on The Soda Jerks. Elsewhere, we discovered several good reviews of Vintage brand root beer which can now be found at Trader Joe's stores.

Update: Obtained the four aforementioned items from the Root Beer Store and wow, the Bulldog is amazing. Two additional recommended root beers to obtain and sample: Hank’s and So Duh! Rockin’. Plus, Centennial Root Beer from Brewbakers in Huntington Beach.

Objective-C and Code::Blocks

Tricky to get this combination operational. The wiki entry is helpful for configuration. Not finding any of the Objective-C libraries in the default installation, we located what might be the correct support files on the TDM site. But after adding these matched libraries, we ended up with compiler warnings and a segmentation fault during the first alloc, using the simple test code on the wiki page. Next thing to try was the troubleshooting suggestion of removing libobjc.dll.a ... but that resulted in a laundry list of "undefined reference to" ... precisely the message the wiki entry claims the removal will avoid!

Finally, what worked was removing the entire mingw installation from the CodeBlocks directory (just delete everything in the mingw directory, version 4.7.1) and install mingw using the installer referenced on the mingw website. During installation, set the install directory to the mingw directory under CodeBlocks and then select to install the C, C++, and Objective-C compilers. This resulted in a good installation of GCC 4.6.2, a warning-free compile, and a faultless run...yay!!! (Remember, you cannot do any Apple development with this configuration, so including foundation.h is not allowed. But you can learn and play with the fundamentals of the Objective-C language on the Windows platform in preparation for moving to a Mac for iOS or OSX app development.)

Artist Clarification

People sometimes mistakenly refer to a bust of Giuliano de' Medici by Michelangelo as a bust of David by the same sculptor. Although they may look similar, a careful study of the two sculptures reveals that the two faces are quite different. Here are links to images in Wikipedia: Giuliano and David.

Galaxy Empire

This free on-line strategy game is extremely engaging and time-consuming. An iOS clone of OGame, it combines elements of science fiction, flight management, factory logistics, planetary exploration, and battle tactics. There are many upgrades including somewhat complex requirements dependencies. For example, the research lab needs to be at level 7 before researching hyperspace technology which is needed before developing hyperspace drives which are required to build battleships.

There are several paths a player can take in this game. For example, the tutorial introduces the mines, the shipyard, research, defenses, constructing a small fleet, attacking an enemy (other players), and colonizing a new planet. After the tutorial, although it might be tempting to try some more attacks, it only makes sense to go back to basics and focus on upgrading infrastructure (mining, defense, ship building, and research) until somewhat stronger.

Two worthwhile tips: 1) Colonize a planet in a system other than the starting system. 2) If a probe is detected by radar prior to attack, deploy all fleet to another colony along with as much material as possible. In the present version of the game, planetary structures (mines, research lab, shipyard, etc.) cannot be damaged or destroyed by enemy fire.

Flight Tycoon tips: To maximize sales, first build the city next to your airport to a population of 50,000 - achievable before level 10 if you replace low-cost buildings with restaurants. When you reach this population, your outbound planes will be fully loaded with passengers.

Next, upgrade your planes as often as you can. The most efficient planes are the hardest to obtain due to the research and mastery process. The Concorde, however, can be purchased from the in-game store and earns about $19K per hour on short flights. If you can, stick to one or two cloud (measure of distance) routes since they pay the most, but require more frequent turn-arounds. Only fly into airports that return full loads.

If you buy fuel when the price dips, you can average under $6.20 a barrel. Expand your airport ramps as soon as you can afford it, but open then sequentially as you acquire aircraft so that friends don't take them all. To minimize losing a ramp when you upgrade an aircraft, buy your new plane first, then quickly drop the old route and build the new one. When friends do fly into your airport, turn them around as quickly as possible - you'll earn a bonus of 20% of the inbound route revenue.

If you follow these tips, you can achieve level 34 in two weeks.

Pocket Planes vs Flight Tycoon: Really enjoying the airport simulator genre. Flight Tycoon employs high resolution graphics while Pocket Planes (soon to be released) prefers low-res graphics like Tiny Tower. Both simulators are free on the iOS platform and share the common goal of growing a fleet of planes to ferry passengers. Presently, we're investigating how to maximize sales (flight earnings) using the most efficient planes and optimal destinations in Flight Tycoon. To learn more about Flight Tycoon, take a look at this walk-through. A preview of Pocket Planes can be found here.

Pocket Planes is expected to be available June 14. Watch the trailer available on YouTube.

Isoball 3: A challenging mental exercise where you construct a pathway for a ball using a fixed set of resources like blocks, inclined planes, bridges, elevators, and directional. In some cases there are multiple solutions to a level. This game is free and runs in Google Chrome.

In the attached photo of level 75, the blue ball drops from the chute, runs down the ramp, gets an added boost from the conveyer belt, makes a right and rolls across a power bridge though a tunnel that pops out at the upper right. From there, the ball goes down the 3-level elevator, makes two more right turns and heads into another tunnel popping out at the upper middle. After passing though the four tunnel openings, the target doors open in the lower left and the ball makes its final descent in the four-level elevator.
