Have you ever wanted to be able to view all running processes (not apps) on your Android devices? Jack Wallen shows you how to do just that.
How many services are running on your Android 11 device? Not apps, but services. What resources are those apps consuming and how long have they been running?
Do you know how to answer those questions? If you’re running Android 10 or newer, you can actually access the information to answer those questions. Why would you need such information? You might have found that your device is responding slowly. You could restart the phone, but what if you could fix the problem without resorting to that measure? You could track down the errant service and then restart it, thereby avoiding a full reboot.
How do you do that? Let me show you.

What you’ll need
In order to view the running services, you’ll need an Android device with at least version 10 of the platform.
How to enable Developer Options
The ability to view running processes in Android is found in the Developer Options. In order to do that, open the Settings app and locate About Phone. In the About Phone section, locate Build Number (Figure A).
Tap the Build Number entry seven times. You’ll be warned when you get close (Figure B).
With Developer Options enabled, you’re now able to view the running services.
How to view the running services on your device
Go back to the Settings app and locate Developer Options. For example, on the vanilla release of Android running on my Google Pixel 5, Developer Options is in Settings | System | Advanced. If it’s not on your phone, you can always search settings for Developer Options. Once you find Developer Options, tap the entry. In the resulting screen, you should see Running Services listed (Figure C).
Tap Running Services to open the app, where you’ll see a listing of all currently running services (Figure D).
If you tap any one of those running services, the entry will open where it can be stopped and restarted. If you see any of those apps consuming a suspiciously large amount of memory, you might want to stop and restart it.
Do, however, be careful. If you stop a crucial service the device might fail to operate properly (and you’ll wind up having to reboot anyway). Even with that caveat, having the ability to view running services is a good tool for anyone who likes to troubleshoot their Android devices with more than just the standard apps and options. This is also a great way for you to test your in-house apps that run as background services on Android.

GeoSim: Photorealistic Image Simulation with Geometry-Aware Composition
Humans can synthesize unperceived events in their heads, for instance, to imagine how an empty street would look during rush hour. The similar capability of computers may be useful in film making or augmented reality.
A recent paper proposes GeoSim, a realistic image manipulation framework that inserts dynamic objects into existing videos.
This method uses the data captured by self-driving cars to build a 3D assets bank. Then 3D scene layout from LiDAR readings and 3D maps is used to add vehicles in plausible locations. The Intelligent Driver Model is used so that the new objects have realistic interactions with existing ones and respect the flow of traffic. Neural networks are employed to seamlessly insert an object by filling holes, adjusting color inconsistencies, and removing sharp boundaries. It is the first approach to fully consider physical realism and outperforms prior research by qualitative and quantitative measures.
Scalable sensor simulation is an important yet challenging open problem for safety-critical domains such as self-driving. Current work in image simulation either fail to be photorealistic or do not model the 3D environment and the dynamic objects within, losing high-level control and physical realism. In this paper, we present GeoSim, a geometry-aware image composition process that synthesizes novel urban driving scenes by augmenting existing images with dynamic objects extracted from other scenes and rendered at novel poses. Towards this goal, we first build a diverse bank of 3D objects with both realistic geometry and appearance from sensor data. During simulation, we perform a novel geometry-aware simulation-by-composition procedure which 1) proposes plausible and realistic object placements into a given scene, 2) renders novel views of dynamic objects from the asset bank, and 3) composes and blends the rendered image segments. The resulting synthetic images are photorealistic, traffic-aware, and geometrically consistent, allowing image simulation to scale to complex use cases. We demonstrate two such important applications: long-range realistic video simulation across multiple camera sensors, and synthetic data generation for data augmentation on downstream segmentation tasks.

Developers: How observability complements the future of monitoring
Commentary: Those who say observability killed monitoring aren’t paying attention. Here’s why.
You can be forgiven if you thought monitoring was passé. Nagios, for example, is probably the best known of the open source monitoring tools, but interest in it has steadily declined for over a decade. Meanwhile, observability tools like OpenTelemetry are hot, though “observability” is arguably a cool new term for much the same metrics, logs, and traces that we’ve been analyzing long before the term was coined.
Indeed, as Lightstep CEO Ben Sigelman has argued, observability isn’t going to replace monitoring “because it shouldn’t.” Observability is all about augmenting monitoring, not replacing it. Here’s why.

Thinking differently about monitoring
I suggested above that observability is really just a fancy way of saying “logs, traces, and metrics,” but that’s overly simplistic. Ultimately, according to Sigelman, observability is about telemetry and storage. Telemetry increasingly is synonymous with OpenTelemetry, the CNCF-hosted open source project. And storage? It’s more than a time series database or a database for storing logs, traces, and transactions. You need both.
The third thing Sigelman insists upon brings us back to monitoring: The health of the system (i.e., monitoring) and understanding change within those systems (i.e., statistical insights buried in all that telemetry data). Sounds important, right? That’s because it is. As Sigelman went on to explain, monitoring really means “an effort to connect the health of a system component to the health of the business.” That’s always going to be a good idea, and feeds into things like more modern approaches to service-level agreements (SLAs) like service-level objectives (SLOs), an approach that Google has helped to popularize.
So why is monitoring suddenly un-cool? Sigelman suggested:
“Monitoring” got a bad name because operators were trying to monitor every possible failure mode of a distributed system. That doesn’t work because there are too many of them. (And that’s why you have too many dashboards at your company.)
Dashboards are nice, but they can also confuse as much as they clarify by bombarding operators with too much data. If we dig into SLOs, however, Sigelman argued that they can help monitoring to evolve beyond noisy dashboards to SLOs that help us gauge the changes in signals that help us track system health.
These SLOs, which set a numerical target for system availability, act as the “peripheral nervous system” of observability, said Sigelman. Rather than relying on a human staring at a dashboard (or, more likely, an array of dashboards) and hoping she can cognitively decipher what’s happening at a glance, the SLO approach instruments things in a way that allows humans before and after the fact to dial up (more cost to operate) or down (lowers costs and increases development velocity) reliability.
So is monitoring dead? Nope. Not even close. Perhaps the way we used to conceive of monitoring is due to be retired, but the practice of monitoring has never been more important. It’s a central component of observability, and likely will be for years to come.
