ConoHa cloud is based in OpenStack Juno. but the latest OpenStack is Ocata.
I released a MetaPackage that can easily install OpenStack Juno client in python 2.7 environment on ConoHa cloud (and Mikumo ConoHa) 4th birthdays.
Janog36 ConoHa: Making GSLB - OpenStack Designate and PowerDNSNaoto Gohko
GSLB, Global server load balancing, is a technology to dispatch DNS requests to the different servers. But the server appliances with these features are complex and expensive. So we try to make it ourselves with the open source softwares.
Designate is one of the components in OpenStack to provide DNSaaS services. It has features that can register DNS records via RESTful APIs and can select backend types; for example choosing BIND, NSD, PowerDNS, etc.
In this session, we will present GSLB with Designate and PowerDNS.
About GMO Internet, Inc.
GMO Internet Group, headquartered in Tokyo, is a leading force in the Internet industry offering one of the most comperehensive ranges of Internet services worldwide.
We are providing a public cloud called “ConoHa” and “GMO APPs Cloud” as part of our services. Both are based on OpenStack.

2015 0228 OpenStack swift; GMO Internet ServicesNaoto Gohko
GMO Internet Inc., has been service provided by the quotient material made of the fact that OpenStack Swift the ConoHa VPS brand and GMO Apps Cloud. discussed the differences between the physical configuration of the OpenStack Swift at rackspace and ConoHa, was carried out optimization of the configuration.
In addition, you have an implementation that provided by Dual-head on multiple merchandise by invoking the swift-proxy for each service.
TechOYAJI 2014 tokyo summer LT; CentOS7 and RDO Icehouse OpenStackNaoto Gohko
CentOS7 is OSS of RHEL7. But we had problems RDO Icehouse OpenStack install with packstack.
This behavior is due to the version notation was introduced in CentOS7 called "7.0.1406". So far, in CentOS7, and we use the notation such as "6.5" treated as values in the decimal point, it was also similar even RHEL.
String introduced in CentOS7 called "7.0.1406" can not be treated as a number.
Confuse itself caused the puppet upstream community that said version number is difficult to make out CentOS7 development community.

セル生産方式におけるロボットの活用には様々な問題があるが,その一つとして 3 体以上の物体の組み立てが挙げられる.一般に,複数物体を同時に組み立てる際は,対象の部品をそれぞれロボットアームまたは治具でそれぞれ独立に保持することで組み立てを遂行すると考えられる.ただし,この方法ではロボットアームや治具を部品数と同じ数だけ必要とし,部品数が多いほどコスト面や設置スペースの関係で無駄が多くなる.この課題に対して音𣷓らは組み立て対象物に働く接触力等の解析により,治具等で固定されていない対象物が組み立て作業中に運動しにくい状態となる条件を求めた.すなわち,環境中の非把持対象物のロバスト性を考慮して,組み立て作業条件を検討している.本研究ではこの方策に基づいて,複数物体の組み立て作業を単腕マニピュレータで実行することを目的とする.このとき,対象物のロバスト性を考慮することで,仮組状態の複数物体を同時に扱う手法を提案する.作業対象としてパイプジョイントの組み立てを挙げ,簡易な道具を用いることで単腕マニピュレータで複数物体を同時に把持できることを示す.さらに,作業成功率の向上のために RGB-D カメラを用いた物体の位置検出に基づくロボット制御及び動作計画を実装する.
This paper discusses assembly operations using a single manipulator and a parallel gripper to simultaneously
grasp multiple objects and hold the group of temporarily assembled objects. Multiple robots and jigs generally operate
assembly tasks by constraining the target objects mechanically or geometrically to prevent them from moving. It is
necessary to analyze the physical interaction between the objects for such constraints to achieve the tasks with a single
gripper. In this paper, we focus on assembling pipe joints as an example and discuss constraining the motion of the
objects. Our demonstration shows that a simple tool can facilitate holding multiple objects with a single gripper.
【DLゼミ】XFeat: Accelerated Features for Lightweight Image Matchingharmonylab
公開URL:https://arxiv.org/pdf/2404.19174
出典:Guilherme Potje, Felipe Cadar, Andre Araujo, Renato Martins, Erickson R. ascimento: XFeat: Accelerated Features for Lightweight Image Matching, Proceedings of the 2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) (2023)
概要:リソース効率に優れた特徴点マッチングのための軽量なアーキテクチャ「XFeat(Accelerated Features)」を提案します。手法は、局所的な特徴点の検出、抽出、マッチングのための畳み込みニューラルネットワークの基本的な設計を再検討します。特に、リソースが限られたデバイス向けに迅速かつ堅牢なアルゴリズムが必要とされるため、解像度を可能な限り高く保ちながら、ネットワークのチャネル数を制限します。さらに、スパース下でのマッチングを選択できる設計となっており、ナビゲーションやARなどのアプリケーションに適しています。XFeatは、高速かつ同等以上の精度を実現し、一般的なラップトップのCPU上でリアルタイムで動作します。
