Tripwire is an intrusion detection system. It monitors file systems and stores various attributes about the files for later comparison. When it detects that a monitored file has changed since the baseline scan, it alerts someone (e.g. system administrator, data security, etc.) via e-mail who can either verify that the change was authorized and update the baseline, or have the change reversed. The Open Source product is based on code provided by Tripwire Inc.. The commercial offering includes a robust reporting and security policy management built around the core product.

Android Applications: Shopping Lists

Home > My Lists > Android Applications > Shopping Lists


I do a lot of the household’s grocery shopping and I’m always running little errands to the grocery, hardware, and big-box department stores. My lists are manifest on paper, in e-mail, and (all too often) in my head. Sometimes I have to consult two or three different lists during a single visit. I needed to find a way to maintain a single, consolidated shopping list, and the tablet seemed like an excellent platform for the job.

[Content last updated on 5/20/2013]


Evaluation Criteria

The basic requirement is that the app reliably maintains a clean list of items that can be crossed off (or at least removed) as necessary. This is simple functionality and there are many Android apps out there that will do the job sufficiently. However, I really didn’t want to retype items that I buy on a regular basis, and it would be great to have a master list that I could use to take inventory around the house before a big shopping trip in the hope of cutting down the number of small errands in the week that follows. Identifying the store for each item is also important.

Here’s a few other considerations:

  • The ability to record an item’s price is of limited value to me for several reasons. First, prices change all the time (even if only by a few cents) and even if I know that one store has the lowest price, I’m not going to make a special trip if it’s the only item I need to buy there. Gas it too expensive these days to care much about a difference of a few cents on a can of green beans. Also, I’m not going to maintain price data for everything I buy across three or four grocery stores. It is nice to know approximately how much something costs and it is helpful to know the sale prices for the current week.
  • Many apps include barcode-scanning functionality, usually for easy lookup of items against a product database. It may be a neat feature, but I’m not going to make it a requirement. In part, I often prefer to be generic. For example, the line item “Shampoo for him” leaves room for choice based on price, availability, and the plain freedom to choose something different once in a while. [Based on my experience after the evaluation was over, this feature worked best with name-brand items and not so well with store-brand items — which happens to include a lot of what we buy!]

Selected App Reviews

OI Shopping List. [v1.6] This app is very simple at first blush but several advanced features make it scale nicely. Multiple shopping lists can be stored. Adding items to a list involves typing the name of the item into a text box at the bottom of the screen and clicking the ‘Add’ button. To check an item off of the list (or cross it off, depending on the theme) just tap it. The app can be configured to hide checked items automatically. The “Clean Up List” function appears to wipe all checked items from the list, but it really only hides them. The “Pick Item” function then lets you add items back to the list as needed. By default, this occurs in a dialogue box; however, there is a setting that allows for the picking of items inline on the list. A “Mark All Items” function allows for quick cleanup so that items can be picked or added anew. Wait, there’s more! Various attributes can be (optionally) set for each item, such as quantity, units, price, tags, priority (numeric), and even notes (requires OI Notepad). If any of the items on the list have a price, then the total is tallied at the bottom. Quantity and unit values precede the name of the item on the list view if they contain values. There are no categories (e.g. Frozen Foods), but tags work well in this capacity (caveat: without autocomplete, the tags would have to be retyped every time). Prices can also the tracked by store. (BUG ALERT! In version 1.6, no matter which item you choose, the Stores dialog box gets stuck on the first item on the list if it is accessed through the Edit Item dialogue box. Long-tapping on the item and choosing “Stores…” works fine.) Here’s the best part! The list can be filtered by store and/or tag! This works even when picking items to add to the list, which means you can set the tag filter while taking inventory around the house and then set the store filter when shopping at a particular store. When the store filter is on, the price for that store is shown! (Unfiltered, it shows the lowest price.) How powerful is that! There is also a barcode scanning function (which requires the Barcode OI Plugin), but I have not tried it.

This app is clearly my favorite because it met my evaluation criteria. It lets me work the way I want to work. I can turn on the inline pick function and go from room to room determining what needs to be purchased (a binary decision). The store filter turns my master list into a store-specific list, and the tag filter limits my choices when taking inventory and allows me to focus aisle by aisle at the store.

Out of Milk. [v3.1.4] This app has one of the best user interfaces in my opinion. Version 1.6 has three functions available: Shopping List, Pantry List, and To-Do List (not reviewed). The Shopping and Pantry lists look very much the same, and multiple lists of each kind can be created; however, these lists are integrated only loosely. In a Shopping List, a line item can include values for quantity, unit, unit price, and category, as well as check boxes for “Tax-Free” and “Coupon”, and a long text field for notes. The list is grouped by category and footed by two price tallies: “Total” and “Remaining Total” (i.e. price total of unchecked items). Setting the tax rate will automatically add tax for all items not marked as “Tax-Free” and prices are adjusted for coupons, either in amount or percentage. (BUG ALERT! I entered an item with quantity of “2” and unit price of $10. On the list it stated in small print, “2 @ $20.00”. This is misleading. “2 @ $10.00 = $20.00 Total” or “Qty: 2 Total: $20.00” would be far less ambiguous.) In a Pantry List, an item still has a unit price, category (with the same values as on the Shopping List), and notes. The quantity and unit values are still available, but not by default. In their stead, a slider control labeled “Amount” ranges continuously from “None” to “Half” to “Full”. The values on the line item are then qualified in small print as “None left”, “Almost empty”, “About half left”, etc. The quantity and unit values take the place of the slider if the “Enter Number Instead” checkbox is checked. The other two checkboxes don’t exist in the Pantry List. Both include a price history (stack array) that is automatically updated when a price is changed. So, it is obvious that the Shopping List function is meant to be used to plan a very specific shopping trip (with the possible side benefit of making you think twice about impulse purchases lest they mess up your perfectly-planned list) and the second function lends itself to keeping a household inventory, either periodic or perpetual (with the downside being that you have to review your entire list as you march through every store and reset the quantities either when items go into the basket or after the purchase is complete). These functions are not mutually exclusive. Use the Pantry List to track items typically kept on hand (like paper towels, soap, etc.) and add non-staple items to the Shopping List (such as steak because it is on sale this week or a bottle of wine for Friday night). This app also has a built-in barcode scanner that found every item I scanned, including desk supplies.

I really like the split Shopping List and Pantry List concept; however, unlike OI, I have to remember what is on each. For example, are bananas on the Pantry List or the Shopping List? Probably the former. Ground beef? Probably the latter.

Grocery IQ. [v2.5.2] This app has a very nice interface and it was going to be my app of choice when I started, but it quickly fell out of favor. For starters, and this was probably a fluke, but the first time I tried to use the app at the grocery store, my list was gone! It reappeared the next day. The barcode scanner would not return any store brand products. In fact, only brand name products could be found in the database. Also, this app is for use with electronic coupons, and I don’t use a lot of coupons anymore, so I moved on to other apps.

To be fair, I just fired up the app before writing this, and was able to find Kroger brand goods. I may revisit it someday, perhaps just for getting the coupons during shopping trips.

Our Groceries. [v2.2.0] This app is very basic. It does support multiple shopping lists and has a large number of generic products in its database (e.g. “eggs” and “milk”).

ZipList. [v2.3] This is a sufficient app that allows multiple lists, and common item attributes, such as quantity, units, size, price, etc. The database includes both generic and name brand items, but I did not try out the barcode scanner. ZipList does have a helpful store feature that lets you search for and maintain a list of favorite stores and customize the aisle order for each. Items can then be categorized by aisle (most have logical defaults) and assigned to particular stores in the list. This automatically sorts store lists to streamline shopping trips and prevent needless walks back and forth across the store.

The weekly ZipList e-mail newsletter includes links to a lot of tasty recipes.

Retail Store Apps

The retail grocers are definitely competing in the mobile arena. I have loaded a few apps, including Kroger, Albertsons, Tom Thumb, Target, and Walmart. They all offer a competitive list of features, including weekly ads, shopping lists, online coupons, store locators, prescriptions, shopper’s club rewards, gift card services, and gift registries.

Again, these apps may be useful for taking advantage of deals and coupon in-store (i.e. pick up an item and scan the barcode to see if there is a coupon), but I’d rather not have to access a half-dozen apps to plan the week’s shopping. Moreover, these apps are going to change more frequently than the generic apps to stay competitive, so I don’t see much value in reviewing them in detail.


Android Applications: Travel

Home > My Lists > Android Applications > Travel


I don’t travel a lot. My job does not call for it and we leave town on holiday once or twice a year…maybe. So, this review isn’t so much a head-to-head comparison of apps as it is a set of experiences and opinions.

[Content last updated on 5/19/2013]


Trip Planning (Generic)

Tripit. This itinerary app is extremely useful! It lets you plan your trip minute-by-minute. You can add specific types of transportation, places to stay and eat, and activities. Both the app and the website is fully functional (rare that both work equally well), and they seem to sync without issue. I think it even looked up my flight information, because I don’t remember entering in all of the details by hand.

BathroomFinder. More to come…

San Francisco 2012

Triposo San Francisco. This app came in really handy before and during the trip. The category listings (“See and do”, “Eat, drink and sleep”, etc.) are easy to browse and help you target places of interest. The map feature, however, paid real dividends! Once I knew what part of town we’d be in on a particular day, I could zoom in to reveal the local restaurants, as well as other things to see and do in the neighborhood. When our plans changed unexpectedly (e.g. “Ewww, I’m not eating there!”), this app provided alternatives.

TripAdvisor City Guide. I didn’t use this app much, and looking back at it, I’m not sure why. It’s very similar to Triposo’s offering, but this one is backed by a website I am familiar with. I will definitely keep TripAdvisor in mind for our next trip, especially since I just found a few cool things we missed in San Francisco while writing this post.

SFMTA Muni+. This app is made for locals, especially those who commute using public transportation and have tight schedules. It provides system alerts including information about current delays as well as future route changes, construction, and other events. The MUNI map is grainy, but the Trip Planner was useful in getting to know the system. It allows you to plan a trip across town, providing transfers and fee information. The CityPASS more or less eliminated the need to calculate fares and printed route maps and bus schedules provided a more comprehensive view, especially useful when more flexibility was necessary.

QuickBART. Very similar to Muni+, but much simpler. It includes a planner function and a static system map. Obviously, the rails are less susceptible to delays than buses.

San Francisco Map. This app by Bill Ray is just a hi-res copy of the system map. It was also useful, though I had the printed map on hand as well.

Android Applications: Web Browsers

Home > My Lists > Android Applications > Web Browsers


Web browsing is an essential part of the tablet user experience, and there is no shortage of browser options available on the Android platform, each with its own strengths and weaknesses. With nothing to lose, I decided to try several. Here are my conclusions.


Evaluation Criteria

Actually, for this post, I’m not going to focus on a list of specific features or performance benchmarks. Browsers perform one basic job and should do so well. No one is going to complain that their browser is too fast or that it seems to handle any and all multimedia content thrown at it without flaw. We just expect these things, and there are plenty of other sites that cover benchmark testing and the like. Also, I was trying to find a good all-purpose browser, which may not be what everyone else needs. Plus, features change over time and good technology today is (hopefully) replaced by better technology tomorrow. That’s not to say that I didn’t have specific requirements going into this evaluation (and I do mention some of them below), but the specific criteria don’t seem to matter as much in the long run as the process for evaluation and the overall philosophy that came about as a result.

The Best

Ultimately, I decided to stick with the big name browsers: Chrome, Firefox & Opera. These proved to be the most stable and the most feature rich. They had by far the biggest footprints, but they were still small in comparison to the space available on my tablet. Tabbed and private browsing functions are big selling points, and these were not available in other smaller offerings, at least not at first. Chrome is my favorite. Its user interface is more slick than Firefox’s (IMHO) and the ability to share open tabs across devices (e.g. with Chromium on my laptop) is very useful. Firefox is still my second-favorite browser, and though the placement of tabs on the side in landscape mode is less efficient, it does make for easy tab navigation. Opera has some nice eye candy, like the Start Page grid, but I have not been pleased with the overall performance or feel, so I usually only open Opera if I need to access a page that won’t load using the other two. Ironically, there were some sites that I visit frequently that would not work in Opera, and even if this improves over time (through patches and/or changes in content) as long as Chrome and Firefox work as well as they do, I don’t really have a vested interest in making Opera by browser of choice. Security, frequency of updates, quality of testing, and other software development issues played a role in the decision to stick with the big guys as well.

The Rest

Each of the other offerings I tried seemed to cater to specific needs. Some emphasized how lightweight they were, which means they would work better on lower end phones than the default browser (and thus, far better than the heavyweights discussed above). Simplicity was also a selling point, targeting users with smaller screens. Of course, there were those few that included user interface features that they hoped would catch on like wild fire. But none of them had it all, or at least enough to effectively compete with Chrome and Firefox for my loyalty. I did try Dolphin Browser (HD & Mini) early on, which came highly recommended by a friend. The magazine view looked very appealing, but again, that’s just eye candy, and I never did latch on to the gesture interface, despite my Palm Pilot nostalgia. I did get really excited about the Pocket browser (formerly Read It Later) for offline browsing, but in practice I never put it to much use. There were others, but the details don’t seem worth mentioning now.

The Future

Does this mean I’m not going to try out new browsers going forward? Not at all. In fact, while I was redrafting this post, I read about the Puffin browser. I had seen the name in passing, but I never looked into it. And who knows what else the future of browsers holds?

Android Applications

ShortURL: http://goo.gl/wUxLzx
Home > My Lists > Technology > Android Applications


This page started off as a list of apps I wanted to try, become a set of reviews, and now contains a mixture of elements that I consider part of my Android experience.


Android & Me

A few years ago, I bought a tablet computer. It was a bit of a luxury, but it proved to be very convenient for things like casual browsing at the coffee shop and checking off shopping list items at the grocery store. I was using it more like a PDA than a browsing platform or ebook reader. I had already started compiling a long list of apps that I wanted to try, and after I started using the tablet on a regular basis, I started posting short reviews for many of them. At some point, it became impossible for me to keep up with the new offerings and all of the updates, and my work on this topic stopped. I continued to use the unit for some time, and then I was given an iPhone by my employer. My need for the tablet dissipated, and now I plan to repurpose the unit as a desktop MP3 player. I am now more interested in documenting my experiences with the Android tablet, retaining whatever remains useful from the reviews.

Reviews

I’m slowly migrating the sections below into bite-sized posts.

Productivity

Editing & Notetaking.

AK Notepad. [468K] By the makers of Catch (below). This appears to be a very simple notepad, but does allow tagging and export.
Catch. [size varies]
Evernote. [6.9M] I have started using Evernote online and love it! The app is great too!
Inkpad Notepad. [445K] I created an account and used this notepad online. It’s clean and simple, but I was hoping to see the same options as are shown on the screenshots for the Android app, namely the ability to create checkbox-laden to-do lists. All I get is blank notebook paper.
OneNote. [7M] Well, first of all, it’s made by Microsoft, which almost automatically disqualifies if from my list; however, I was impressed with it a few years ago when tablet PCs (read: laptops with swivel screens) first came out. It’s limited to a certain number of notes before you have to pay a license fee, and it does not appear that notes can be exported. I think I have better options.

Planners.

DGT GTD + Toodledo. [1.3M + 233K] This app syncs with Toodledo (with extension), which I already use for GTD components. I need this, but I’m not holding my breath. It’s third-party and only in beta testing.
Pocket Informant. [2.4M] It syncs with Toodledo and I like the book layout interface! The User Guide is available in PDF format on the Market page. I need to read this before deciding. For $13, which is a lot for an Android app, I expect it to work well.

Religion

Laudate (Catholic One). [4.8M] This is one of the first apps I had to evaluate. Confession: I installed it on a tab in the store. It has a lot of good stuff! I wrote to the author who confirmed that the lectionary and divine office require an Internet connection, but smaller content, such as prayers, rosary, and stations do not. Interestingly, the NAB Bible relies on a connection, but the Douay Rheims does not — I wonder if this is due to copyright restrictions. I came to realize that I could download most, if not all, of the same content to an SD card in PDF or TXT format, and/or cache it with Read It Later (see above).

Photography

Skitch. [1.5M] I definitely want this app if for nothing but to annotate pictures to post on Facebook.
Measure & Sketch.
My Measures & Dimensions.

Utilities (was System/Toys)

Bump. [2.7M] Recommended by a friend, but it looks like it’s most useful for phones, and I’m not sure I’d use it for much of anything at all.
Graffiti. [free:4.1M pro:2M] Palm-style data input. From what I’ve read, it disables some browser zooming.
Sky Map. [2.2M] Great reviews, and it’s not critical for me, so I will probably use it. I can get back into astronomy again!
Swype. Similar to Graffiti (above). I don’t see it on the Market anymore.
Voxer. [3.2M] PTT/walkie talkie functionality. Probably not necessary on a tablet. Perhaps on a phone. Recommended by a friend.
Connectbot. [707K] Installed this at a store. All I could do was ‘cd’ and ‘ls’. No grep, sed, perl, etc. The good stuff (if it exists) probably requires rooting the tablet.
Juice Defender. [size varies] Comes in regular ($0), plus ($2), and ultimate ($5). Recommended by a friend. I will probably try it.
Lookout. [3.3M] Security and antivirus suite recommended by a friend.
App Organizer. Recommended by a friend to keep app icons organized and not cluttered.

Yet To Research

Milage Tracker. I’d like to capture the data once.
Mindmapping. I’ve used MindMeister in the past. I don’t use this type of tool often.
DOT Reader. I’ve used Graphviz in the past and can create the files with a text editor.
PicsArt – Photo Studio
Sketch Notes
FreeNote
Note Plus +
GMemory

Home > My Lists > Technical Notes > Linux > RCS


RCS is a version control tool released in 1982 as an alternative to the (then) decade-old SCCS written by Bell Labs. It is part of GNU now and is an underlying technology for almost all large version control solutions on the market. There is plenty of info on RCS out there; these notes only cover what I need to remember about RCS but tend to forget over time.

Notes

  • The rcs, ci, co, rcsdiff, rcsmerge, rcsclean, & rlog commands are RCS operations.
  • Archives are stored in ./RCS if it exists or in ./ by default.
  • New archives are initialized with ‘rcs -i filename’ or by just checking it in the first time.
  • The -t flag adds a description of the file (instead of being prompted).
  • ci deletes the working file by default.
  • The -m flag adds a log message (instead of being prompted).
  • “ci -l” locks the file (implicit checkout), and “ci -u” leaves a read-only copy behind.

TiddlyWiki: My Experience

Filed under: Computer Software,Online Tools,TiddlyWiki — Brandon @ 5:55 pm

Home > My Lists > Technical Notes > TiddlyWiki > TiddlyWiki: My Experience


I have fallen in and out of love with TiddlyWiki several times since August 2006. It started with this ‘blog post by “euicho” written almost exactly one year earlier. I’ve used it successfully for several small projects, though more often than not, what began with a TiddlyWiki blossomed into a ‘blog, a website, or a full-blown application. So, if anything, it’s good for working out a design for what I really want to do. It’s extremely versatile and addictive too! Here are some highlights from my TiddlyWiki experience.


Notepad. Believe it or not, this ‘blog began as a TiddlyWiki…sort of. I wanted to publish my notes on a number of topics on a free “personal” page. Cobbling pages together by hand was too labor-intensive, especially when I wanted to change the look-and-feel of the whole site at one time. I wasn’t learned in CSS at the time and I tried automating the compilation of a site using flat data files, HTML templates, make, and a few other scripting utilities. All of it was taking up way too much time. TiddlyWiki was the answer. For a very good reason (which now escapes me), I decided to use ‘blog technology instead, which has worked out far better in the long run; however, I might not have made that leap without TiddlyWiki in the middle.

School Notes. I finally broke down and bought a laptop while I was in graduate school. This allowed me to take all of my notes electronically, at least for the last couple of years in the program. I really wanted to go paperless, so I relied on scans, downloads, and other methods for keeping it all digital. I even recorded lectures on occasion. TiddlyWiki was my notebook of choice. With a wiki mindset, I would create Tiddlers for topics and then referenced them from Tiddlers containing basic outlines of both textbook chapters and lectures. Doing most of the work before hand allowed me to take minimal notes during class, which meant that I could pay more attention to the professor and participate in the discussion more fully.

Big Finish. The proverbial icing on the cake came in my capstone course. The professor (who happened to be the department chair) believed heavily in the power of organization. A student who keeps an organized and complete notebook will always do well, he would tell us often. As such, we had to turn in our class notebooks to the professor at the end of the semester – for a grade! I hadn’t done that since, oh let’s see, high school! It was degrading, but admittedly, a very wise requirement on his part. I had one little problem. I told him that I could print out the contents of my “notebook”, but with his permission I’d rather turn in a 100%-electonic copy. He agreed, so long as it was easily viewed on his PC with little effort. Everything was linked in the TiddlyWiki. I just burned the CD and wrote the instrucitons on the label: “insert into CD-ROM drive and open notebook.html”. I guess it worked, because I aced the course. He retired the next year.

Original Battle Chess Capture Sequences

Filed under: Computer Software — Brandon @ 9:23 am
Tags: , , , , , , , ,

Many moons ago, when I had time to do things for fun or for no real reason whatsoever, I documented the animation sequences for Interplay‘s original 1988 version of Battle Chess. I’m taking the time now to post these notes here, for no real reason whatsoever.


About The Pieces

Pawn: armored warrior, wielding a lance
Bishop: wearing a hooded robe, mitre, and knife-topped staff
Knight: wearing full armor and a cape, with shield and sword

Queen: typical dress, fights with energy bolts
King: hunched-over old man with a variety of tricks

The Attack Sequences

Pawn takes… Pawn: attacks with lance, first the toe, then the head
Bishop: opens hole in the ground with lance, bishop falls in
Knight: kick to the groin, knight falls over
Rook: breif fight, rook falls and is smashed to pieces
Queen: stabs her in the back with a knife
King: takes crown with lance, king throws a fit
Bishop takes… Pawn: basic hand-to-hand combat, stabs him with bladed staff
Bishop: vaporizes him with staff (magic?)
Knight: very similar to capture of pawn
Rook: crumbles him with staff (magic?)
Queen: barehanded blade blocks, stabs her through the torso
King: slices king into three pieces
Knight takes… Pawn: basic hand-to-hand combat, stabs him with sword
Bishop: stabs him in the gut, then beheads him, bishop disappears
Knight: cuts off his arms and legs *
Rook: knocks legs out from under him, rook falls and crumbles
Queen: reflects lightning with shield, turning her into a dragon
King: failed beheading, cuts sceptor and disrobes him
Rook takes… Pawn: pawn surrenders and is smashed into a metal ball
Bishop: two blows to the head
Knight: smashes him into a helmet with feet
Rook: fist fight, fist goes down through head and body
Queen: devours her whole
King: flattens him, king is dropped and floats to ground
Queen takes… Pawn: vaporizes lance, pawn tries to runs, but is blasted
Bishop: chars him in place, his skeleton falls into a bone pile
Knight: vaporized inside his armor
Rook: blasts him into a pile of rubble
Queen: blasts her and she shrinks into nothing
King: blasts him, he disintigrates, leaving robe, crown, sceptor
King takes… Pawn: reveals hidden ball mace in sceptor and smacks him
Bishop: shoots him in the chest after missing his head and feet**
Knight: bats bomb to him with his sceptor
Rook: shrinks with with some sort of burning powder
Queen: they embrace, she tries to knife him and he knocks her down
King: not possible

* Reenactment of Black Knight scene from Monty Python’s Quest for the Holy Grail
** Reenactment of swordsman scene from Raiders of the Lost Ark

The Video

Years later, someone captured the sequences in a video and posted them to YouTube. Take a look:

Home > My Lists > Technical Notes > Linux > Screen


Screen is a good solution for anyone who would benefit from using multiple Unix/Linux terminals (consoles) at one time. This utility divides the screen into two or more sections, each running a different session. This has many uses; for example, you can run a command and watch the output in one pane and tail (-f) a related log file in another.


Presently, I’m collecting links about screen and will write more if needed:

Basic General Ledger Software


A few years ago, I had a need for an extremely-basic GL for a project. The following is a list of the most-basic apps I could find. I ended up writing my own, but I kept the list just in case the need were to arise again.


  • Lazy8 is a simple, Java-based, Open Source GL now available for Ubuntu!
  • OneStep is a Windows-based GL that can be used as a POS system.
  • Brinance is a CLI app written in Perl.
  • Ledger is another Unix CLI GL app. (formerly NewArtisans.com)
