Features


Demystifying Stablecoins
Volatility has marked the emergence of cryptocurrencies. In response, there has been a flood of proposals for new designs that purport to provide a stable exchange rate. These so-called stablecoins may face numerous regulatory hurdles, but they are probably here to stay.
- Jeremy Clark, Didem Demirag, and Seyedehmahsa Moosavi, Concordia University


Case Study


To Catch a Failure: The Record-and-Replay Approach to Debugging
Mozilla developed the record-and-replay debugging tool, called rr, for internal use, but unexpectedly, it came to be widely used outside of Mozilla. Its developers discuss the challenges of debugging and the reason for the success of rr.
- A discussion with Robert O'Callahan, Kyle Huey, Devon O'Dell, and Terry Coatta


Columns / Departments


COMMIT TO MEMORY
Chipping Away at Moore's Law
The shrinkage of transistors predicted by Moore's law has slowed down in recent years. The technology exists for chips as small as 7nm, but the high cost of manufacturing them has prevented their widespread use.
- Jessie Frazelle

KODE VICIOUS
Kode Vicious Plays in Traffic
The use of software to control moving vehicles raises plenty of safety issues. But there are design principles to follow that may help ameliorate the risk.
- George Neville-Neil

ESCAPING THE SINGULARITY...
The Best Place to Build a Subway
Developing software can be compared with building a city's infrastructure. While it may be easier to start with a clean slate, the reality is that you must work around existing structures. The same holds true for computer systems.
- Pat Helland

EVERYTHING SYSADMIN
Communicate Using the Numbers 1, 2, 3, and More
The length of a list has a bearing on how listeners perceive the content. Knowing this will make you a better communicator.
- Thomas A. Limoncelli

THE MORNING PAPER
How do Committee's Invent? And Ironies of Automation
Two papers that have withstood the test of time hold true today. The first revisits Conway's law and the effect of organizational forces on design and development. The second looks at the idea that the more we automate, the more we depend on human skill.
- Adrian Colyer

FAQ


Why is the text so small?

The maximum text size on newer, high-resolution (more than 2 megapixel) device screens may be too small for some individuals to read easily. Use the links above to preview the first six pages of an issue. If you find the text too small, you may prefer to use the browser-based version of the app until this problem is resolved.


I'm having trouble viewing the browser version of the app

Make sure you have the Flash plugin and JavaScript enabled. Try turning off any ad-blocking software. Make sure you're using one of the more recent browser releases. We suggest the minimums of Chrome 23, Firefox 19, IE 10, and Safari 5.


How do I log in to the browser version?

The user session for the app is not tied to myACM so you must log in separately.

The login screen only appears after you have advanced beyond the 6-page preview. When in the preview, click any of the links and you should see a prompt to log in.


How do I get a PDF of the issue?

We offer PDF versions of all articles. If you go to an individual article on the site, you should see a PDF icon in the upper right e.g. http://queue.acm.org/detail.cfm?id=2844732

Or, if you go to the table of contents for an issue in the Digital Library, you should see links to download PDFs for all articles in the issue e.g. http://dl.acm.org/citation.cfm?id=2838344&preflayout=flat

Or, if you log in to the browser version of the app, you should see a download icon in the upper right that will download the full PDF of the entire issue https://mydigitalpublication.com/publication?m=38068&l=1

Or, again in the browser version of the app, click the lower-right 'More' icon ("...") to reveal additional options, including a print function.

An additional option is to click the 'Contents' icon in the upper right (looks like the old Windows logo) which will pull up links to all articles without formatting or images. You may need to click the screen to expand the top and bottom menus to reveal the icons.


How do change my subscription?

ACM members should contact ACM (https://myacm.acm.org/dashboard.cfm) to update their passwords, renew subscriptions, etc.

iOS users should contact Apple to update their passwords, renew subscriptions, etc.

For all subscriptions and issue purchases for the Android and browser-version of the app, contact [email protected].


How do I get the navigation menu/panels to reappear?

Just tap the screen in an area that is not a link.

For the browser version, you may need to right-click. (ctrl-click on Mac).


Explain the members. non-members, subscription thing again?

ACM professional members (not student members, not users with plain web accounts) get full access to acmqueue on iOS, Android, or as a browser "app" (for lack of a better term). They simply login using their member account login.

Everyone else (non-members) have the choice of (a) joining the ACM and getting full access to acmqueue (among other things), (b) buying an annual subscription to the magazine as an iOS app, Android app, or browser app, or (c) buying a single issue, again as an app on their phone or browser.


Certain things look odd in Opera

The Opera browser is not supported, sorry. We only saw one CSS bug in Opera on Android, but otherwise it should still look the same as most other platforms.


I just found out my subscription has expired, why wasn't I notified?

ACM members's accounts are handled through the ACM https://myacm.acm.org/dashboard.cfm

iOS subscribers should be getting notification from Apple.

For Android subscribers and browser version subscribers there is currently no mechanism to remind them of subscription cancelations. Sorry.


I have a student ACM membership. Why can't I log in?

Unlimited access to acmqueue is granted to professional memberships only.


I have a subscription to the app. Can I use that to log in to the browser version?

No, subscription to the iOS app, Android app, and browser version do not permit access to either of the other versions.
